Marina Crime — Port Phillip Bay

Boat Theft & Marina Crime in Melbourne: The Hidden Threats Lurking at Your Berth

Imagine this: your yacht is docked at St Kilda Marina. It’s midnight. You’re away. A motion sensor could have stopped an intruder. A heat detector might have caught a fire. A flood sensor could have saved your bilge from overflow.

But there’s nothing.

We’ve seen the damage — flooded interiors at Royal Brighton Yacht Club, scorched panels at Pier 35, stolen gear in Docklands. These aren’t isolated events. They’re signs of a growing threat in Melbourne’s marinas.

Hidden security threats in Melbourne marinas — Sipko Security

Ajax: The Smart Standard for Yacht Security

Ajax Systems provide wireless, tamper-proof protection built for marine conditions. No wires. No guesswork. Just smart security.

MotionProtect

Detects movement inside cabins or on decks — triggering instant alerts the moment an intruder steps aboard.

DoorProtect

Secures hatches and cabin doors from intrusion — any unauthorised opening triggers an immediate alarm.

FireProtect

Senses smoke and rapid temperature rise — catching onboard fires before they spread to the hull or engine bay.

LeaksProtect

Alerts to water ingress before it’s too late — protecting your bilge, engine room, and interior from flooding damage.

Ajax Hub 2 Plus

Stays connected via Wi-Fi, Ethernet, or 4G — even offshore. The brain of your marine security system, always online.

Compact, Battery-Efficient & Interference-Resistant

All Ajax devices are engineered for marine environments. Managed through the Ajax app, you get instant alerts and full remote control — wherever you are in the world.

Our Approach

Why We Don’t Install Cameras — And Why Ajax Is Enough

At Sipko Security, we specialise in yacht security systems that don’t rely on cameras. Why? Because Ajax sensors provide faster, more reliable alerts — without the limitations of surveillance hardware in marine environments.

Common issues with onboard cameras:
  • Power-hungry systems
  • Saltwater damage and corrosion
  • Weak connectivity at remote docks
  • Privacy concerns aboard private vessels

That’s why we focus on precision: motion, fire, water, and entry detection — with instant alerts and no distractions. For speed, simplicity, and reliability, Ajax is your solution.

Instant Detection

Ajax sensors trigger in milliseconds — no buffering, no lag, no missed events. You’re alerted the moment something happens.

Marine-Grade Reliability

Wireless, tamper-proof, and built to withstand humidity and salt air — Ajax hardware is engineered for the harshest marine conditions.

Always-On Coverage

With 4G, Wi-Fi, and Ethernet failover, your system stays connected even when shore power or internet is unreliable.

Live Protection

Real-Time Alerts. Real Peace of Mind.

Security means knowing what’s happening — in real time. With Ajax, you’re always connected:

  • Instant alerts via app, SMS, or call
  • Custom automation — arming, alarms, and scenarios
  • Shared access for crew or marina staff
  • Event logs for tracking every action

At Sandringham Marina, a yacht owner received a midnight alert. Thanks to MotionProtect, a prowler was stopped before damage occurred. That’s the power of early detection — and the value of Sipko Security.

Boat Theft & Marina Crime in Melbourne: What the Numbers Actually Say

Victoria’s property crime rate is at its highest level since 2016 — and marinas are not immune. Here’s what the official data tells us about the real risk to your vessel right now.

Marina Suburb Risk Breakdown

Marina / Suburb Key Risk Factors Risk Level
St Kilda Marina High foot traffic, open foreshore, proximity to nightlife precinct High
Docklands Urban marina, mixed-use precinct, overnight vessel access points High
Williamstown Isolated overnight berths, limited lighting in outer slips Medium–High
Sandringham Affluent target profile, weekend-only foot traffic, equipment theft risk Medium–High
Royal Brighton YC High-value vessels, seasonal gaps in occupancy, perimeter access Elevated
Mornington Remote location, limited police patrol frequency, storm exposure Elevated

Risk levels are assessed based on LGA crime data from the Crime Statistics Agency Victoria and publicly reported incidents. They are indicative, not official classifications.

Why Marina Crime Is Underreported

  • Vessels are unoccupied for days or weeks — owners often don’t discover theft or vandalism until their next visit, making it impossible to pinpoint when it occurred.
  • Marine theft is not tracked as a separate category by the Crime Statistics Agency — boat-related incidents are folded into broader “other theft” and “property damage” codes, masking the true scale.
  • Many incidents go unreported entirely — owners fear insurance premium increases or believe police have limited capacity to investigate marine property crime.
  • Victoria’s overall theft rate rose 30% in the year to March 2025 — the broader crime surge directly increases risk at every marina along Port Phillip Bay.
  • Victoria Police Water Police Unit focuses primarily on safety and search-and-rescue operations — property crime prevention on moored vessels largely falls to owners themselves.
Don’t become part of the statistics.

A professionally installed Ajax alarm system is the most effective deterrent against marina theft, vandalism, and onboard emergencies — and Sipko Security installs them across Melbourne’s entire coastline.

The 7 Most Vulnerable Points on a Yacht — And How to Secure Each One

Most yacht break-ins don’t happen by force — they happen through overlooked entry points and unmonitored spaces. Here’s exactly where your vessel is exposed, and the specific Ajax sensor that closes each gap.

01

Companionway Hatch

The main entry point into the cabin — and the first target for any intruder. A standard lock offers minimal resistance to a determined thief, especially at night when no one is watching.

Ajax DoorProtect Magnetic contact sensor detects any opening — triggers instant app alert and siren within seconds.
02

Cockpit Locker

Cockpit lockers store outboard motors, life rafts, flares, and expensive sailing gear. They’re often left with basic padlocks and are easily accessible from the dock without boarding the vessel.

Ajax DoorProtect Plus Detects both opening and shock/vibration — catches tampering attempts before the lock is broken.
03

Engine Bay

Engine bays are a fire risk from fuel leaks, overheating, and electrical faults — and a theft target for outboard engines and marine batteries. An undetected engine fire can sink a vessel in minutes.

Ajax FireProtect Plus Detects smoke, heat, and carbon monoxide — purpose-built for enclosed engine spaces with extreme temperature tolerance.
04

Shore Power Inlet

Shore power cables are frequently stolen from marina berths — they’re expensive, easy to disconnect, and gone in under 30 seconds. The inlet area also presents a water ingress risk during storms.

Ajax MotionProtect Outdoor Covers the deck and connection area — detects any approach to the vessel’s power connection point after hours.
05

Navigation Electronics

Chartplotters, VHF radios, autopilot heads, and AIS transponders are high-value, easily removed, and difficult to trace. A single smash-and-grab can cost $10,000–$30,000 in equipment alone.

Ajax MotionProtect (Interior) PIR motion detection inside the cabin — any movement at the nav station triggers an immediate alert.
06

Fuel Tank Access

Fuel theft from marina berths is a growing problem across Port Phillip Bay. Beyond theft, an unsecured or damaged fuel cap creates a serious fire and explosion risk — particularly in enclosed bilge spaces.

Ajax DoorProtect + FireProtect DoorProtect on the deck access hatch; FireProtect in the bilge to catch fuel vapour ignition before it escalates.
07

Dinghy Davits & Tender Storage

Dinghies, tenders, and outboard motors stored on davits or the stern are among the most commonly stolen items from moored yachts. They’re exposed, accessible from the water, and rarely alarmed. A stolen tender can cost $5,000–$20,000 and leave you stranded offshore.

Ajax MotionProtect Outdoor + LeaksProtect Outdoor motion detection covers the stern and davit area; LeaksProtect in the tender bilge alerts to water ingress if the dinghy is tampered with or cast adrift.

One System. All 7 Points Covered.

A properly configured Ajax system — installed by Sipko Security — addresses every vulnerability on this list. Wireless sensors, no hull penetrations, and full remote control from your phone. We assess your specific vessel and build a protection plan around it.

Port Phillip Bay Weather Risk

How Melbourne’s Weather Destroys Unprotected Boats & Yachts at Marina Berths

Port Phillip Bay looks calm — until it doesn’t. Official data from the Bureau of Meteorology and the Victorian Government’s own Coastal Hazard Assessment reveals a bay that is far more dangerous than most yacht owners realise.

The 5 Weather Threats Every Melbourne Yacht Owner Faces

Sudden Southerly Busters

Melbourne’s notorious southerly changes can arrive with almost no warning — wind speeds jumping from 10 to 50+ knots in minutes. Vessels on exposed berths can be driven into pontoons, snapping lines and causing hull damage before anyone can respond.

Lightning Strikes

Melbourne averages over 25 thunderstorm days per year. A mast is the tallest point in any marina — making your yacht a natural lightning rod. A direct strike can destroy electronics, blow through the hull, and start fires in the bilge.

Storm Surge & Tidal Flooding

The 2024 Port Phillip Bay Coastal Hazard Assessment — released by DEECA — confirmed escalating coastal inundation risk around the bay. Areas including Elwood, St Kilda, and South Melbourne are identified as high flood-risk zones, directly affecting marina infrastructure and moored vessels.

Bilge Flooding from Heavy Rain

Melbourne’s rainfall is unpredictable — intense downpours can overwhelm cockpit drains and fill bilges faster than automatic pumps can handle. An unmonitored vessel can take on dangerous amounts of water overnight, especially if a hatch seal has degraded.

Extreme Heat & UV Degradation

Melbourne’s summer temperatures regularly exceed 38°C. Prolonged heat accelerates fuel vapour build-up in engine bays, degrades hatch seals, and can cause electrical fires in poorly ventilated spaces — all while the owner is nowhere near the vessel.

How Ajax Gives You Advance Warning — Before Damage Occurs

LeaksProtect — Flood & Water Ingress

Placed in the bilge, engine bay, and any low-lying interior space, LeaksProtect detects water the moment it appears — sending an instant alert to your phone before the bilge pump is even triggered. Stops a slow leak from becoming a sunken vessel.

FireProtect Plus — Heat & Smoke Detection

Monitors temperature rise and smoke simultaneously. In an engine bay where heat builds rapidly on a 38°C Melbourne day, FireProtect Plus triggers an alert well before a fire takes hold — giving you time to act remotely or call for help.

Ajax Hub 2 Plus — 4G Failover Connectivity

Storms knock out shore power and Wi-Fi. The Hub 2 Plus automatically switches to 4G cellular backup — so your alarm system stays online and keeps sending alerts even when the marina loses power during a southerly buster.

MotionProtect Outdoor — Storm Intruder Detection

Storms create cover for opportunistic thieves — reduced visibility, noise masking, and fewer people around. MotionProtect Outdoor uses dual PIR technology to distinguish between weather movement and a person boarding your vessel, even in heavy rain.

Weather doesn’t wait. Neither should your protection.

Ajax flood, fire, and motion sensors give you real-time alerts the moment conditions threaten your vessel — day or night, storm or calm. Sipko Security installs and configures every system for Melbourne’s specific marine environment.

Ajax vs Traditional Wired Alarm Systems: Which Is Better for Boats?

Not all alarm systems are built for the marine environment. Here’s an honest, side-by-side comparison of Ajax wireless systems against traditional wired alarms — across every factor that matters on a boat.

Comparison Criteria
Ajax Wireless Recommended for marine use
Traditional Wired Standard land-based system
Installation Complexity
Time, tools, and hull penetrations required
Winner

Fully wireless — no cable runs, no hull penetrations, no drilling. A complete system can be installed in a single day with minimal disruption to the vessel.

Requires extensive cable runs through bulkheads, bilges, and engine spaces. Hull penetrations create water ingress risk. Installation typically takes multiple days.

Saltwater & Humidity Resistance
Corrosion, condensation, and marine environment durability
Winner

Ajax sensors are sealed units with no exposed wiring. Outdoor-rated devices carry IP55 certification. No cable connectors to corrode — the single biggest failure point in marine wired systems.

Cable insulation degrades rapidly in salt air. Junction boxes corrode. Connector pins oxidise, causing intermittent faults and false alarms. Typical lifespan in marine environments: 3–5 years before major issues.

Battery Life & Power Independence
Operation during shore power loss
Winner

Each Ajax sensor runs on its own long-life battery (up to 7 years on some devices). The Hub 2 Plus has a built-in backup battery and 4G failover — the system keeps running even when shore power is cut in a storm.

Relies on the vessel’s 12V or 240V supply. A single power failure — common in storms — can disable the entire system. Backup batteries in the panel are often undersized and rarely tested.

Remote Access & App Control
Arm, disarm, and monitor from anywhere
Winner

Full remote control via the Ajax app — arm, disarm, view event logs, receive push notifications, SMS, or calls. Share access with crew or marina staff. Works from anywhere in the world with a phone signal.

Most traditional panels offer no native app. Third-party communicators can be added but require additional hardware, separate subscriptions, and often have limited functionality compared to purpose-built systems.

False Alarm Rate
Triggered by corrosion, vibration, or environmental factors
Winner

Ajax uses dual-technology detection and intelligent signal processing to filter environmental noise. MotionProtect Outdoor specifically distinguishes between weather movement and human presence — dramatically reducing false alerts.

Corroded connections are the leading cause of false alarms in marine wired systems. Vibration from waves and wakes can trigger poorly mounted sensors. Salt-contaminated PIR lenses produce erratic readings.

Scalability & Expansion
Adding sensors as needs change
Winner

Add any new Ajax sensor in minutes — pair it to the hub via the app, no tools required. Upgrade from a 3-sensor starter system to full vessel coverage without touching existing hardware.

Every new sensor requires a new cable run. Expanding a wired system on a vessel means more hull penetrations, more labour, and more potential corrosion points. Rarely cost-effective after initial installation.

Total Cost of Ownership
Installation, maintenance, and replacement over 5 years
Winner

Higher upfront hardware cost than basic wired panels, but dramatically lower over 5 years. No cable replacement, no corrosion repairs, no specialist marine electrician callouts. Battery replacement is the primary ongoing cost.

Lower initial hardware cost, but marine environments accelerate component failure. Expect significant maintenance costs from year 2 onwards — corroded cables, failed sensors, and panel faults are common and expensive to diagnose.

⚓ The Verdict

Ajax Wins on Every Marine Metric That Matters

For boats and yachts in Melbourne’s marine environment, there is no meaningful competition. Wired systems were designed for buildings — not for vessels exposed to salt air, vibration, flooding, and power interruptions. Ajax was built for exactly these conditions. The result is a system that is more reliable, easier to manage, and cheaper to own over time.

Get Ajax Installed on Your Vessel
Ajax wins on installation — no hull penetrations, no cable runs, one day to complete
Ajax wins on durability — sealed sensors, no exposed wiring to corrode in salt air
Ajax wins on power resilience — 4G failover keeps the system online when shore power fails
Ajax wins on remote control — full app management from anywhere in the world
Ajax wins on false alarm rate — intelligent dual-tech detection filters marine noise
Ajax wins on 5-year cost — no corrosion repairs, no cable replacements, no callouts

Melbourne Marina Security Risks: St Kilda, Williamstown, Sandringham, Docklands & More

Every marina along Port Phillip Bay has a different risk profile. Here’s what you need to know about each one — the specific threats, the CCTV coverage gaps, and the Ajax configuration Sipko Security recommends for vessels berthed there.

St Kilda Marina

St Kilda, Port Phillip Bay — Inner Melbourne
⚠ High Risk
  • High foot traffic from adjacent foreshore precinct — easy public access to pontoons after hours
  • Proximity to St Kilda’s nightlife strip increases opportunistic theft risk overnight
  • City of Port Phillip identifies St Kilda as a high flood-risk zone — storm surge exposure
  • Mixed berth ownership — difficult to monitor who belongs and who doesn’t
CCTV Gap: Marina CCTV covers entry gates and car parks but has limited coverage of individual berths and stern areas — particularly in the outer pontoon rows where most thefts occur.
Recommended Ajax Configuration
DoorProtect — companionway MotionProtect Outdoor — deck LeaksProtect — bilge Hub 2 Plus — 4G backup Ajax Siren — deterrent

Royal Brighton Yacht Club

Brighton, Bayside — 12 km from Melbourne CBD
⚠ Elevated Risk
  • High-value vessel profile — premium yachts attract targeted, pre-planned theft rather than opportunistic crime
  • Seasonal occupancy gaps — many vessels unattended for weeks during winter
  • Exposed western aspect — direct exposure to Port Phillip Bay southerly swells and storm surge
  • Navigation electronics and tender equipment are primary theft targets
CCTV Gap: Club CCTV is concentrated at the clubhouse and main entry. Outer berths and the water-side approach — accessible by dinghy — have minimal camera coverage, creating a blind spot for water-borne intruders.
Recommended Ajax Configuration
DoorProtect — companionway + lockers MotionProtect — nav station MotionProtect Outdoor — stern/davits LeaksProtect — bilge FireProtect Plus — engine bay

Sandringham Yacht Club

Sandringham, Bayside — 20 km from Melbourne CBD
⚠ Elevated Risk
  • Weekend-only foot traffic — marina is largely deserted on weekday nights, reducing natural surveillance
  • Affluent vessel profile makes it a known target for equipment theft — outboards, electronics, sails
  • Exposed southern aspect — significant storm and swell exposure during winter months
  • Sandringham Marina was the site of a confirmed MotionProtect intrusion stop — see our case study above
CCTV Gap: Clubhouse and car park are monitored. Pontoon arms beyond the first two rows have no dedicated camera coverage — a known gap that experienced thieves exploit on weeknight visits.
Recommended Ajax Configuration
MotionProtect — cabin interior MotionProtect Outdoor — cockpit DoorProtect Plus — companionway + lockers LeaksProtect — bilge Hub 2 Plus — 4G

Williamstown Marina

Williamstown, Hobsons Bay — 12 km west of CBD
⚠ Medium–High Risk
  • Isolated outer berths with limited lighting — particularly vulnerable after 10pm
  • Industrial surroundings reduce natural foot traffic and community surveillance
  • Mixed commercial and recreational vessel use — harder to identify suspicious activity
  • Hobsons Bay foreshore exposed to westerly weather systems from the open bay
CCTV Gap: Entry and fuel dock are monitored. The outer arms — where most recreational yachts are berthed — have significant lighting and camera gaps, especially on the northern side of the marina.
Recommended Ajax Configuration
DoorProtect — companionway MotionProtect Outdoor — deck + stern LeaksProtect — bilge FireProtect — engine bay Ajax Siren Outdoor

Docklands Marina

Docklands, Melbourne CBD — Victoria Harbour
⚠ High Risk
  • Urban CBD location — 24/7 foot traffic from restaurants, bars, and entertainment venues creates constant cover for thieves
  • High-density residential towers overlook the marina but provide no active security
  • Stolen gear from Docklands is easily moved via public transport — fast getaway routes
  • Superyacht and prestige vessel berths attract targeted, professional theft operations
CCTV Gap: Docklands has the highest public CCTV density of any Melbourne marina precinct — but cameras face public walkways, not vessel decks. The water-facing side of every berth is a blind spot.
Recommended Ajax Configuration
DoorProtect — all hatches MotionProtect — interior MotionProtect Outdoor — full deck LeaksProtect — bilge FireProtect Plus — engine bay Hub 2 Plus — 4G + Ethernet

Pier 35 / Mordialloc Creek

Mordialloc, Bayside — 27 km from Melbourne CBD
⚠ Medium–High Risk
  • Creek-side location with multiple informal access points — not a single gated entry
  • Shallow draft vessels and trailer boats mix with moored yachts — varied security awareness among berth holders
  • Flooding risk from Mordialloc Creek during heavy rainfall events — bilge flooding a documented issue
  • Limited street lighting on the creek-side access path after dark
CCTV Gap: Minimal formal CCTV infrastructure. The creek-side approach and informal access paths have no camera coverage — making this one of the least monitored marina environments in Melbourne’s bayside.
Recommended Ajax Configuration
DoorProtect — companionway LeaksProtect — bilge (priority) MotionProtect Outdoor — deck FireProtect — engine bay Hub 2 Plus — 4G

Mornington Harbour

Mornington Peninsula — 60 km from Melbourne CBD
⚠ Elevated Risk
  • Remote location — 60 km from Melbourne means response times for any incident are significantly longer than inner-bay marinas
  • Limited police patrol frequency — Mornington Peninsula policing is stretched across a large geographic area
  • Exposed to Bass Strait weather systems — more severe storm conditions than inner Port Phillip Bay marinas
  • Seasonal tourism influx brings unfamiliar visitors to the foreshore — harder to identify suspicious behaviour
  • Many vessels left unattended for extended periods between Peninsula sailing season events
CCTV Gap: Harbour entry and the main pier have some camera coverage. However, the outer anchorage area and the majority of swing moorings have zero CCTV visibility — and no shore-based monitoring after business hours. Remote location makes this the highest consequence gap of any marina on this list.
Recommended Ajax Configuration — Extended Remote Setup
DoorProtect — companionway + all hatches DoorProtect Plus — cockpit lockers MotionProtect — interior MotionProtect Outdoor — full deck perimeter LeaksProtect — bilge + engine bay FireProtect Plus — engine bay Hub 2 Plus — 4G primary (no Ethernet reliance) Ajax Siren Outdoor — maximum deterrence

Ajax Sensors — How Many for Your Boat

How to Choose the Right Security System for Your Vessel Size

A day sailer needs a different setup to a bluewater yacht. A motor cruiser has different risks to a superyacht. Here’s exactly what Sipko Security recommends — sensor by sensor — for every vessel type on Port Phillip Bay.

Day Sailer

Under 7 metres Starter Protection
Recommended Sensors
3–4 devices
  • 1× DoorProtect — companionway hatch
  • 1× MotionProtect — cabin interior
  • 1× LeaksProtect — bilge
  • 1× Ajax Hub 2 — nav area, 4G SIM
Hub Placement

Mount the Hub 2 in the main cabin, centrally positioned to reach all sensors. Keep it away from the bilge — a dry, ventilated spot near the nav station is ideal.

Power tip Connect to 12V vessel supply with the built-in battery as backup. A day sailer rarely has shore power — 4G SIM is essential.
Aiphone Intercom

Not typically required for vessels under 7m. Focus budget on Ajax sensors.

If berthed at a gated marina: A single Aiphone IX-SS-2G video station at the dock gate covers shore-side access — available within 15 km of Brighton.

Cruising Yacht

7 to 12 metres Standard Protection
Recommended Sensors
6–8 devices
  • 2× DoorProtect — companionway + fore hatch
  • 1× DoorProtect Plus — cockpit locker (shock)
  • 1× MotionProtect — main cabin
  • 1× MotionProtect Outdoor — cockpit/deck
  • 1× FireProtect Plus — engine bay
  • 1× LeaksProtect — bilge
  • 1× Hub 2 Plus — 4G + Wi-Fi failover
Hub Placement

Hub 2 Plus in the nav station — central to the vessel, within range of all sensors fore and aft. At 7–12m, a single hub covers the full vessel without repeaters.

Connectivity tip Use shore power Wi-Fi as primary when berthed; 4G SIM as automatic failover when away from the marina or during power outages.
Aiphone Intercom
Recommended for marina berths: Aiphone IX-DV video door station at the dock gate or berth access point. Allows you to see and speak to anyone approaching your vessel from shore — integrated with your phone.
Service area: Available within 15 km of Brighton, Melbourne. Covers St Kilda, Sandringham, Royal Brighton, and Williamstown marinas.

Bluewater Yacht

12 metres and above Advanced Protection
Recommended Sensors
10–14 devices
  • 3× DoorProtect — companionway, fore hatch, aft cabin
  • 2× DoorProtect Plus — cockpit lockers (shock detection)
  • 2× MotionProtect — main saloon + aft cabin
  • 2× MotionProtect Outdoor — cockpit + foredeck
  • 2× FireProtect Plus — engine bay + galley
  • 2× LeaksProtect — main bilge + engine bilge
  • 1× Hub 2 Plus — nav station, 4G + Ethernet
Hub Placement

Hub 2 Plus at the nav station. At 12m+, verify radio range reaches the foredeck and aft cabin — Ajax range is 2,000m open air but hull materials can reduce this. A single ReX range extender may be needed on larger vessels.

Offshore tip For bluewater passages, a dedicated 4G SIM with a data plan ensures alerts reach you even when the vessel is away from marina Wi-Fi for extended periods.
Aiphone Intercom
Strongly recommended: Aiphone IX-DV at the dock gate plus a second station at the vessel’s boarding point (stern or midships). Two-station setup gives full shore-to-vessel access control.
Crew access: Multiple user credentials allow crew members to be granted or revoked access independently — ideal for charter or shared ownership arrangements.

Motor Cruiser

Any length — engine-focused risks Fire & Flood Priority
Recommended Sensors
8–12 devices
  • 2× DoorProtect — cabin entry + helm station
  • 1× DoorProtect Plus — engine hatch (vibration)
  • 1× MotionProtect — main cabin
  • 2× MotionProtect Outdoor — bow + stern deck
  • 2× FireProtect Plus — engine bay (both engines if twin)
  • 2× LeaksProtect — engine bilge + main bilge
  • 1× Hub 2 Plus — helm station or nav area
Hub Placement

Mount the Hub 2 Plus at the helm station or in the main cabin — away from engine vibration and heat. Motor cruisers generate more electrical interference than sailing yachts; keep the hub at least 1m from inverters and alternators.

Engine bay priority Motor cruisers have a significantly higher engine fire risk than sailing yachts. FireProtect Plus in every engine bay is non-negotiable — not optional.
Aiphone Intercom
Recommended — helm-to-dock: Aiphone IX-DV at the dock gate with a master station at the helm. Allows the skipper to screen visitors and control dock gate access without leaving the vessel.
For private docks: A weatherproof Aiphone panel at the dock entrance with video feed to a tablet or phone is the most practical setup for privately moored motor cruisers.

Superyacht

20 metres and above Full Vessel Coverage
Recommended Sensors
16–30+ devices
  • 4–6× DoorProtect — all cabin entries, hatches, lazarette
  • 3–4× DoorProtect Plus — all deck lockers + tender garage
  • 4–6× MotionProtect — all interior zones (saloon, cabins, crew quarters)
  • 4× MotionProtect Outdoor — bow, stern, port, starboard deck
  • 3–4× FireProtect Plus — engine room, galley, generator room
  • 3–4× LeaksProtect — all bilge zones + engine room
  • 2× Hub 2 Plus — fore and aft, with ReX extenders as needed
  • 2× Ajax Siren Outdoor — bow + stern deterrence
Hub Placement

Two Hub 2 Plus units — one forward (nav station or bridge), one aft (crew area or engine room vicinity). Use Ajax ReX range extenders to ensure full coverage across all decks. Both hubs connect to the same Ajax account for unified monitoring.

Redundancy tip Configure both hubs with independent 4G SIMs and separate Ethernet connections. If one hub loses connectivity, the other maintains full system operation.
Aiphone Intercom
Full multi-point system: Aiphone IX Series IP intercom — master station on the bridge, sub-stations at the gangway, tender garage, and crew entrance. Video at all external entry points.
Marina gate integration: Aiphone panels at the marina berth gate and the vessel’s boarding point, with remote unlock capability from the bridge or owner’s phone — full access control from anywhere.
Note: Aiphone installation available within 15 km of Brighton. Contact Sipko Security to discuss superyacht requirements.

AMSA Fire Regulations — Vessel Safety Australia

Yacht Fire Safety in Australia: Rules, Risks & Real-Time Detection

Fire is one of the most catastrophic events that can happen on a vessel — and one of the most preventable. Here’s what Australian law requires, what the data shows, and how Ajax FireProtect goes far beyond the minimum standard.

What Australian Law Requires for Vessel Fire Safety

  • 1
    Fire extinguishers — mandatory on all powered vessels

    Under Victoria Police recreational vessel safety requirements (aligned with AMSA guidelines), all powered recreational vessels must carry at least one approved fire extinguisher. Larger vessels require multiple extinguishers positioned at key locations.

  • 2
    Reportable incidents include fire — Marine Safety Act (Vic)

    Under the Victorian Marine Safety Act, fire is a reportable marine incident. The master of any vessel involved in an onboard fire must report to Victoria Police as soon as possible. Failure to report is an offence.

  • 3
    AMSA Marine Order 15 — fire protection construction standards

    Marine Order 15 sets out fire protection, detection, and extinction requirements for regulated Australian vessels. While primarily targeting commercial vessels, it establishes the benchmark that recreational vessel owners should aspire to meet.

  • 4
    Gas safety on marine craft — Energy Safe Victoria

    Energy Safe Victoria requires all gas appliances on vessels to be properly secured and ventilated. Gas cylinder compartments must have a drain at the base. Improper gas installation is a leading cause of onboard fires and explosions.

  • 5
    No legal requirement for smoke detectors on recreational vessels

    Here’s the critical gap: Australian law does not currently mandate smoke or heat detectors on recreational yachts and boats. A fire extinguisher is required — but nothing to alert you that a fire has started while you’re away from the vessel.

The legal minimum is not enough. A fire extinguisher only helps if someone is on board to use it. When your vessel is unattended at a Melbourne marina, the legal minimum leaves you with nothing — no alert, no warning, no chance to act before the fire spreads.

How Ajax FireProtect Goes Beyond the Legal Minimum

FireProtect — Smoke & Heat Detection

Exceeds minimum

Detects both smoke and rapid temperature rise simultaneously. Unlike a passive extinguisher, FireProtect sends an instant alert to your phone the moment conditions indicate a fire — giving you time to call for help or act remotely, even from the other side of Melbourne.

FireProtect Plus — Adds Carbon Monoxide Detection

Marine recommended

FireProtect Plus adds CO detection — critical for engine bays and enclosed spaces where incomplete combustion from generators or engines can produce lethal carbon monoxide before any visible smoke appears. No legal requirement exists for CO detection on recreational vessels — Ajax provides it anyway.

Remote Alert — App, SMS & Call

No equivalent in law

Australian law requires an extinguisher on board — it says nothing about alerting the owner when they’re not there. Ajax fills this gap entirely: push notification, SMS, and automated phone call the moment FireProtect triggers, regardless of where you are.

Tamper-Proof & Self-Monitoring

Always active

Ajax FireProtect continuously monitors its own battery level and sensor status. If the battery runs low or the device is tampered with, you receive an alert — so you always know your fire detection is operational. A passive extinguisher gives you no such assurance.

4G Failover — Alerts Even When Shore Power Fails

Storm-proof

Fires often start during or after storms — when shore power is cut and Wi-Fi is down. The Ajax Hub 2 Plus automatically switches to 4G cellular, ensuring fire alerts reach you even when the marina loses power. The legal minimum has no equivalent capability.

Meet the legal minimum — then go beyond it.

Sipko Security installs Ajax FireProtect and FireProtect Plus across Melbourne’s marina fleet. We’ll position sensors in every high-risk zone on your vessel — engine bay, galley, bilge — and configure instant alerts so you’re never the last to know.

Yacht & Boat Security FAQ Melbourne

Frequently Asked Questions: Boat & Yacht Security in Melbourne

Everything Melbourne boat and yacht owners ask us about marina theft, vessel security systems, and Ajax alarm installation — answered honestly.

Yes. The Ajax Hub 2 Plus has three independent communication channels: Wi-Fi, Ethernet, and 4G cellular. When shore power or marina Wi-Fi drops out, the hub automatically switches to 4G — keeping your system online and sending alerts to your phone regardless of where the vessel is moored.
Yes — full remote control via the Ajax app on iOS or Android. Arm, disarm, check the status of every sensor, view event logs, and receive live alerts from anywhere in the world. You can also share access with crew members or marina staff, with individual permissions for each user.
Ajax sensors are sealed units with no exposed wiring or connectors — the primary failure point in traditional wired marine systems. Outdoor-rated devices carry IP55 certification, meaning they’re protected against dust and water jets. For interior sensors, the sealed housing prevents salt air and condensation from reaching the electronics. Sipko Security selects the appropriate device for each location on your vessel.
Battery life varies by device and usage, but most Ajax sensors last between 3 and 7 years on a single battery under normal conditions. The Ajax app notifies you well in advance when any battery is running low — so you’re never caught off guard. The Hub 2 Plus also has a built-in rechargeable backup battery that activates automatically if shore power is interrupted.
Both options are available. Ajax supports self-monitoring via the app — you receive push notifications, SMS, and automated calls directly. If you prefer professional monitoring, Ajax integrates with licensed monitoring centres who can dispatch security or emergency services on your behalf. Sipko Security can advise on the best option for your usage pattern and marina location.
Ajax uses dual-technology detection and intelligent signal processing specifically designed to reduce false alarms. MotionProtect Outdoor uses dual PIR sensors that must both detect movement simultaneously before triggering — this filters out wave-induced vibration, wind, and small animals. Sipko Security also configures sensitivity settings during installation to match your specific vessel and berth conditions.
It depends on your vessel’s size and layout. A day sailer under 7m typically needs 3–4 devices. A cruising yacht 7–12m needs 6–8. A bluewater yacht 12m+ needs 10–14. Motor cruisers and superyachts require more, particularly for engine bay fire detection. Sipko Security assesses your specific vessel and provides a precise recommendation — see our vessel size guide above for full details.
No. Ajax is a fully wireless system — no cable runs, no hull penetrations, no drilling through bulkheads. Sensors are mounted using marine-grade adhesive or screws into interior surfaces only. A complete installation on most vessels takes a single day and leaves the hull entirely intact. This is one of the key advantages of Ajax over traditional wired marine alarm systems.
Sipko Security installs Ajax marine security systems across Melbourne’s entire coastline — including St Kilda Marina, Royal Brighton Yacht Club, Sandringham Yacht Club, Williamstown Marina, Docklands, Mordialloc, and Mornington Harbour. Aiphone intercom installation is available within 15 km of Brighton. Contact us to confirm coverage for your specific marina.
Yes. Ajax LeaksProtect is a dedicated water ingress sensor placed in the bilge, engine bay, or any low-lying space. The moment water contacts the sensor, it sends an instant alert to your phone — well before the bilge pump is overwhelmed. This is particularly important for Melbourne’s marina environment where heavy rainfall and storm surge can cause rapid bilge flooding in unattended vessels.
Yes. The Ajax app supports multiple users with individual access levels. You can grant crew members the ability to arm and disarm the system, while restricting access to settings and configuration. Access can be revoked instantly from the app — ideal for charter arrangements, shared ownership, or when crew changes occur.
Aiphone is a professional intercom system installed at dock gates, marina entrances, or your vessel’s boarding point. It gives you audio and video communication with anyone approaching from shore — and lets you control gate or dock access remotely from your phone. It’s the shore-side complement to your Ajax onboard system. Sipko Security installs Aiphone within 15 km of Brighton, covering most of Melbourne’s major marinas.
Yes. Ajax Systems devices are RCM (Regulatory Compliance Mark) certified for use in Australia and New Zealand, meeting Australian Communications and Media Authority (ACMA) requirements. Sipko Security is an authorised Ajax installer — all systems are installed to manufacturer specifications and Australian standards.
Many marine insurers offer premium reductions for vessels with professionally installed alarm systems — particularly those with monitoring capability. We recommend contacting your insurer directly to confirm their requirements. Sipko Security can provide documentation of your Ajax installation for insurance purposes. Some policies also require proof of a security system to honour theft or damage claims.
Most installations are completed in a single day. For smaller vessels (under 7m), installation typically takes 2–4 hours. Larger yachts and motor cruisers may require a full day. We schedule installations at your marina berth — no need to move the vessel. Contact us on +61 406 432 691 to book a consultation and installation date.
Your Ajax system moves with the vessel — all sensors are wireless and self-contained. The Hub 2 Plus connects via 4G wherever there is mobile coverage, so the system works at any marina, anchorage, or private dock without any reconfiguration. If you add an Aiphone intercom at a new marina, Sipko Security can install a new shore-side unit within our service area.
