AED Cabinet & Public-Access Defibrillator Guide Australia
Reviewed by the Medibc First Aid Team — last updated May 2026.
According to the Heart Foundation Australia, around 25,000 Australians suffer out-of-hospital cardiac arrest each year. Survival rates jump from ~10% to 70%+ when an AED (automated external defibrillator) is applied within 3 minutes — but those same survival numbers collapse to under 5% if the device is locked in a back office or hidden in a cupboard. The AED only saves lives when bystanders can find it, reach it, and deploy it FAST.
That's where the cabinet matters. This guide covers the four CARDIACT cabinet types (standard indoor, alarmed, alarmed + strobe, outdoor lockable), mounting hardware (wall brackets, free-standing pillars), ANZCOR placement guidelines, and how to register your workplace AED so paramedics can direct bystanders to it during nearby cardiac arrests.

Why AED cabinets matter
Visibility wins seconds
In a real cardiac arrest, every second without CPR + defibrillation cuts survival by 7-10%. A cabinet with green/white biohazard-style signage tells passers-by "the AED is HERE" the moment they look up. Stuffed in a drawer or office cupboard, the device is functionally invisible.
Protection from the environment
AEDs are precision medical devices with batteries and pad gel that degrade in heat, humidity and dust. Cabinets keep the device within its rated operating range (typically 0-50C for indoor, climate-controlled for outdoor). Australian summer carparks routinely exceed 60C inside vehicles — a cabinet is non-negotiable for outdoor placement.
Theft deterrence
Public-access AEDs cost $1,500-$3,000 each. Alarmed cabinets sound a 90-100dB siren on door open — valuable in unmanned locations (community centres after hours, school exterior walls, marinas, council parks). Lockable outdoor cabinets add a fire-emergency break-glass front for legitimate use while keeping casual tampering out.
Tamper-evident closure
Cabinets include break-seals, snap closures, or alarmed contacts so you KNOW when the device has been accessed. Important for: investigating opportunistic non-emergency openings, maintenance logging, and audit trails for WHS compliance.
The four CARDIACT cabinet types — which one for which site
Type 1: Standard indoor cabinet
Plain wall-mounted box with clear front and biohazard signage. No alarm, no electronics. Suits: indoor staffed offices, dental surgeries, GP clinics, school staff areas, factories with always-present staff. Cheapest option ($150-300) for AED protection where theft and accidental access aren't material risks.
Type 2: Alarmed indoor cabinet
Same form factor as standard, plus a 90-100dB siren that sounds when the door is opened. The alarm: 1) Alerts nearby staff that the AED is being deployed (so they can call 000 in parallel), 2) Deters casual theft and pranks. Battery-powered (typically 9V) with a multi-year life. Suits: open-plan offices, schools, gyms, community centres, retail.
Type 3: Alarmed + strobe cabinet
Adds a high-intensity flashing strobe light to the audible alarm. Visual alert for noisy environments (factories, concert venues, gyms with loud music, busy public transport hubs) where the siren alone might be missed. Slightly larger cabinet, same battery requirements.
Type 4: Outdoor alarmed lockable cabinet
Weather-rated (IP55 or better) cabinet for outdoor public-access placement. Climate-controlled internal heating (winter) and ventilation (summer) keep the AED within operating range. Break-glass front for legitimate emergency access, deadbolt lock for security. Suits: community AED schemes, council parks, surf clubs, sports ovals, school exterior walls accessible 24/7.
Mounting hardware — brackets and stands
Wall brackets
Simple metal cradle for the AED to sit in — no door, no enclosure. Cheapest option ($30-60). Suits: indoor low-risk staffed offices where the AED is visible, accessible, and theft/temperature isn't a concern. Most often used as a secondary mount inside an alarmed first-aid room.
Free-standing pillars / stands
1.3-1.6m tall column with cabinet mounted on top. Wheeled or floor-anchored. Suits: foyers, lobbies, hotel reception, large open spaces where wall mounting isn't practical. Provides 360-degree visibility and a "this is here, deploy me" presence.
Combined mounting
Most workplace setups: alarmed indoor cabinet on the main floor + wall bracket in the first-aid room or training space. Total cost ~$300-500 covers a high-visibility, theft-deterred AED with a backup mounting for training/replacement.
Where to place the AED — ANZCOR guidance
The 3-minute rule
ANZCOR Guideline 11.1 recommends placing AEDs so any bystander can: deliver CPR within 1-2 minutes, AND apply the AED within 3 minutes of cardiac arrest. That means: from the highest-occupancy area of your workplace, a person can RUN to the AED, back, attach pads, and start the device within 3 minutes elapsed.
Practical placement rules
- Main thoroughfare — near reception, in the staff room, along a corridor — not hidden in an office
- Shoulder height (1.4-1.6m to cabinet centre) for easy reach
- Within 3-minute round trip from staff-room and entrance
- Near a phone for 000 calls and signage pointing to the AED
- Visible from main pedestrian thoroughfares
- Not behind locked doors during operating hours
- Multi-storey: 1 AED per floor over ~1,000 m2, or per lift bay in larger buildings
Signage
Use the international AED sign (green-and-white "heart with lightning") + arrows directing from main thoroughfares. Add the sign at: building entrance, lift lobby, staff room, and the AED itself. Backlit signs in low-light areas. Multi-language signage if your workplace serves a diverse community.
Public-access vs workplace AEDs
Workplace AED
Inside a staffed workplace (office, factory, school during hours). Accessible to staff and visitors. Standard or alarmed indoor cabinet is adequate. Registered with your local Ambulance Service so 000 can direct bystanders.
Public-access AED (PAD)
Available to the public 24/7 outside your premises. Requires weather-rated outdoor cabinet, lockable, climate-controlled. Mandatory registration with the national AED location registry and integration with the GoodSAM / Heart of the Nation responder apps. Council, surf club, sports club, school exterior wall placements.
The GoodSAM responder network
The GoodSAM app (NSW, Vic, ACT, Tas, SA, WA, partial Qld) notifies CPR-trained volunteers and AED-equipped first responders within 500m of a confirmed cardiac arrest. Your registered AED appears in the app for volunteers. Free to register at the state Ambulance website.

What you'll need
AED make and model, serial number, exact placement address + suite/room, photograph of the cabinet location, hours of accessibility, contact person, language(s) of signage. Update annually or when anything changes.
Maintenance — cabinet + AED
Monthly checks
- AED status indicator (green light) — visible through clear cabinet front
- Pads in date — check expiry on the cabinet door
- Battery expiry — check sticker
- Alarm battery (cabinet electronics) — test alarm sounds when door opens
- Cabinet clean — wipe dust, check no obstruction
- Signage visible — not blocked by furniture or new walls
Annual professional check
A first aid services provider (St John, Red Cross, Defibrillators Australia) can do a full AED + cabinet audit annually: function test, log download, pad replacement, battery condition, training records for first aiders. Costs $150-300/year. Document in the WHS register.
Post-deployment
If the AED is used in a real cardiac arrest: 1) Download the event log per the manufacturer's instructions, 2) Replace pads (single-use), 3) Check battery level (most pads use ~5% battery per use), 4) Re-seal the cabinet, 5) Re-register/update with the registry, 6) WHS incident report. Don't put a used unit back without checking pads + battery.
Industry-specific placement
Schools
One AED per main building, in a corridor near reception or staff room. PE staff trained in HLTAID009 minimum. Outdoor cabinet at the sports oval if available 24/7 for community sport. Register with the state Ambulance Service.
Gyms and sports clubs

One AED per major work zone or per 1000 m2 floor space. Alarmed cabinets in offices, wall brackets in workshops near first-aid stations. Outdoor alarmed cabinets at site gates and amenities blocks.
Hospitality and retail
Visible cabinet near the main customer area (foyer, behind reception, common corridor). Staff trained to grab and deploy. Particularly valuable in: restaurants with mature clientele, casinos, large entertainment venues.
Council and public-access
Outdoor alarmed lockable cabinets at: town squares, shopping precincts, sports ovals, surf clubs, parks. 24/7 accessible — registered with national AED registry + Ambulance Service. Some councils run "AED-on-every-corner" programs targeting one device per 200m in CBDs.
Frequently asked questions
Do I need a cabinet for my workplace AED?
Strongly recommended. An AED cabinet: 1) Makes the device visible (most have green LED + biohazard-style green-and-white sign), 2) Protects the AED from dust, knocks and tampering, 3) Provides theft protection in alarmed/monitored cabinets, 4) Keeps it at the correct operating temperature, 5) Signals 'serious workplace' to staff and visitors. Open wall-mount brackets work for low-risk indoor offices but cabinets are the standard for public-access AEDs in Australia.
What's the difference between alarmed and unalarmed AED cabinets?
Unalarmed cabinets just provide visibility and protection. Alarmed cabinets sound a 90-100dB siren when the door opens - alerts nearby staff that the AED is being deployed (so they can call 000) and deters theft. Strobe-light variants add visual alert for noisy or busy environments. Connected/monitored cabinets (like CARDIACT Connect) send a 4G/cellular alert to a monitoring service when opened - useful for 24/7 public-access locations or unstaffed sites where you need to know an AED was deployed.
Where should I install an AED cabinet in my workplace?
ANZCOR recommends placing AEDs so any cardiac-arrest casualty can have one applied within 3 minutes. Practical rules: 1) Within 3-minute round trip from the highest-occupancy areas (entrance, reception, staff room, gym, pool deck), 2) Visible from the main thoroughfare, 3) Adult shoulder height (1.4-1.6m to the centre of the cabinet), 4) Near a phone for 000 and clear signage, 5) Within reach of staff trained in HLTAID009 (CPR) and HLTAID011 (provide first aid). Multi-story buildings need one AED per floor over 1000 sqm.
Do AEDs need to be inside or can they go outdoors?
Outdoor placement is encouraged for community access (parks, shopping centres, schools, marinas) - but ONLY in weather-rated outdoor cabinets with internal heating/cooling. CARDIACT outdoor alarmed cabinets are IP rated, climate-controlled to keep the AED within its 0-50C operating range, and lockable to prevent vandalism. Indoor cabinets in non-weather-rated installations will fail in Australian summer heat or coastal humidity. Check the AED manufacturer's storage spec before choosing the cabinet.
Should I register my workplace AED with the Ambulance Service?
Yes - free national registration via the Registry of AED Locations (registermyaed.org.au or via Ambulance Victoria, NSW Ambulance, etc.). Registration: 1) Lets paramedics and 000 dispatchers direct bystanders to your AED during a cardiac arrest nearby, 2) Connects to the GoodSAM/Heart of the Nation responder apps, 3) Demonstrates WHS due diligence, 4) Is free. Update the registration when: device is moved, accessibility changes (e.g., after-hours building closure), or device is replaced/upgraded.
