An automated external defibrillator, or AED, is one of the most important emergency devices a workplace, school, sports club or public venue can have on site. When sudden cardiac arrest occurs, early CPR and early defibrillation can make a critical difference while emergency services are on the way.
For Australian buyers, choosing an AED is not just about finding the cheapest defibrillator online. The right AED should suit the location, users, maintenance requirements, training level and environment where it may be needed.
This guide explains how to choose an AED in Australia, what features matter, where AEDs should be placed and what workplaces, schools and community groups should check before buying.
Key Takeaways
- An AED is designed to guide users through defibrillation during a suspected sudden cardiac arrest.
- Workplaces, schools, sports clubs, gyms, community venues and public access sites may all benefit from having an AED available.
- The best AED is easy to find, easy to use, well maintained and matched to the environment where it is stored.
- Important buying factors include pad type, battery life, prompts, adult and paediatric use, IP rating, storage cabinet, warranty and replacement consumables.
- AED pads and batteries have expiry dates and must be checked regularly.
- Training is strongly recommended, even though AEDs are designed to guide users through the emergency process.
- For workplaces and organisations, AED selection should form part of a broader first aid and emergency response plan.
Quick Comparison: AED Buying Considerations
| Buying Factor | Why It Matters | What to Check |
|---|---|---|
| Ease of use | The AED may be used by someone with limited training during a stressful emergency. | Clear voice prompts, visual prompts, simple pad placement guidance and intuitive operation. |
| Adult and child use | Schools, sports clubs and public venues may need paediatric capability. | Child pads, paediatric key, child mode or compatible accessories. |
| Battery and pad life | AEDs must be ready when needed. | Battery expiry, pad expiry, replacement cost and availability. |
| Durability | AEDs may be stored in busy, dusty, outdoor or vehicle environments. | IP rating, shock resistance, storage case and environmental suitability. |
| Storage and visibility | An AED is only useful if people can find it quickly. | Wall cabinet, signage, alarmed cabinet, location and access after hours. |
| Maintenance | AEDs need regular checks and replacement consumables. | Status indicator, self-tests, inspection schedule and responsible person. |
| Training support | Confidence improves response speed and reduces hesitation. | CPR/AED training, staff refreshers and clear emergency procedures. |
| Supplier support | Replacement pads, batteries and guidance should be easy to access. | Australian supplier support, consumable availability, warranty and documentation. |
What Is an AED?
An AED is a portable emergency device designed to analyse a person’s heart rhythm during a suspected cardiac arrest and advise whether a shock is needed. If a shock is advised, the AED guides the user through the process using voice prompts, visual prompts or both.
AEDs are designed so that people without advanced medical training can use them during an emergency. However, training is still strongly recommended because it helps users recognise cardiac arrest, start CPR, attach pads correctly and respond with more confidence.
Who Should Consider Buying an AED?
An AED may be valuable in any setting where people gather, work, exercise, study, visit or spend extended time on site.
Common AED Locations Include:
- Workplaces and offices
- Schools and childcare centres
- Gyms and fitness centres
- Sports clubs and recreation facilities
- Community halls and clubs
- Shopping centres and retail spaces
- Construction sites and industrial workplaces
- Warehouses and logistics facilities
- Places of worship
- Retirement villages and aged care facilities
- Remote worksites and rural properties
- Public access venues
- Vehicles used for events, security, mining, outdoor work or emergency response
If a location has higher foot traffic, physical activity, older visitors, remote access, delayed emergency response times or known cardiac risk factors among the population, an AED may be especially worth considering.
Why AED Access Matters
Sudden cardiac arrest can happen without warning. When it occurs, the person is unresponsive and not breathing normally. CPR helps maintain circulation, while an AED can deliver a shock if the device detects a shockable rhythm.
The goal of having an AED on site is to reduce the time between collapse, CPR and defibrillation.
This is why AED placement matters as much as AED ownership. A defibrillator locked in an office, hidden in a cupboard or stored far away from the highest-risk area may not be practical in a real emergency.
How to Choose an AED in Australia
When comparing AEDs, start with the setting where the device will be used. A school, gym, rural workplace, community venue and mine site may all need slightly different features.
1. Choose an AED That Is Easy to Use
During an emergency, the person using the AED may be stressed, emotional or inexperienced. Clear instructions matter.
Look for features such as:
- Clear voice prompts
- Visual instructions or diagrams
- Simple pad placement guidance
- Minimal buttons
- Clear shock button on semi-automatic models
- Status indicator showing the device is ready
- Metronome or CPR guidance where available
The easier the device is to follow, the more suitable it may be for public access and general workplace use.
2. Decide Between Semi-Automatic and Fully Automatic AEDs
A semi-automatic AED analyses the heart rhythm and, if a shock is advised, tells the user to press a button to deliver the shock.
A fully automatic AED analyses the rhythm and, if a shock is advised, delivers the shock automatically after warning users to stand clear.
| AED Type | How It Works | Common Consideration |
|---|---|---|
| Semi-automatic AED | User presses the shock button if the AED advises a shock. | Some organisations prefer that the responder makes the final button press. |
| Fully automatic AED | AED delivers the shock automatically if a shock is advised. | May reduce hesitation, but users must clearly follow stand-clear prompts. |
Both types still analyse the rhythm and only advise or deliver a shock when the device determines it is appropriate.
3. Check Adult and Paediatric Capability
If the AED may be used in a school, childcare centre, sports club, family venue or community setting, check whether it supports paediatric use.
Paediatric capability may come through:
- Separate child pads
- A paediatric key or switch
- A child mode setting
- Compatible paediatric accessories
Make sure staff or responders know where child pads or accessories are stored and how to use them.
4. Review Pad and Battery Expiry Dates
AED pads and batteries are consumable items. They have expiry dates and must be replaced according to the manufacturer’s instructions.
Before buying an AED, check:
- Expected battery life
- Expected pad life
- Replacement pad cost
- Replacement battery cost
- Availability of adult and child pads
- Whether pads are pre-connected
- Whether the AED has a visible readiness indicator
An AED with hard-to-source consumables can become a problem later. Reliable access to replacement pads and batteries is an important part of ownership.
5. Consider the Environment and IP Rating
Where will the AED be stored? A climate-controlled office has different requirements from a sports ground, pool area, workshop, vehicle, farm, warehouse or remote worksite.
For tougher environments, consider:
- Water and dust resistance
- IP rating
- Temperature storage range
- Shock and vibration resistance
- Carry case protection
- Outdoor cabinet suitability
- Exposure to heat, humidity, dust or rain
If the AED will be outdoors or in a vehicle, environmental suitability becomes especially important.
6. Think About Storage, Signage and Access
Buying the AED is only part of the decision. You also need to decide where it will live.
AED storage should be:
- Visible
- Easy to access
- Clearly signed
- Close to likely emergency locations
- Known to staff, volunteers or members
- Accessible during operating hours
- Considered for after-hours access where appropriate
Many organisations use a wall cabinet with clear AED signage. Some sites may choose an alarmed cabinet or outdoor cabinet, depending on access and security needs.
7. Check Warranty and Supplier Support
An AED is not a product you want to buy from a supplier who cannot support it later.
Before purchasing, check:
- Warranty period
- Australian supplier support
- Availability of pads and batteries
- User manual and documentation
- Maintenance guidance
- Replacement accessories
- Any product alerts or recall history
Supplier support matters because AED ownership continues long after the first purchase.
AEDs for Workplaces
For workplaces, AED selection should be linked to the first aid risk profile. Consider the type of work, number of people, site layout, visitor numbers, working hours and distance from emergency medical help.
Workplaces That May Benefit From an AED Include:
- Large offices
- Warehouses
- Factories and workshops
- Construction sites
- Mining and industrial sites
- Gyms and physical training facilities
- Hospitality venues
- Retail centres
- Remote or isolated worksites
- Transport and logistics hubs
For multi-level or large workplaces, one AED may not be enough if it cannot be accessed quickly from all areas. Consider travel time, not just building size.
AEDs for Schools and Childcare Centres
Schools and childcare centres should think carefully about adult and child use, visibility, staff confidence and access during sport, excursions and community events.
When buying an AED for a school, check:
- Paediatric capability
- Adult and child pads
- Placement near high-traffic or sports areas
- Access during school events
- Staff CPR and AED training
- Clear signage
- Emergency response procedure
- Regular pad and battery checks
Schools may also need to consider whether the AED is accessible outside normal hours when facilities are used by sports clubs or community groups.
AEDs for Sports Clubs, Gyms and Recreation Facilities
Sports clubs and fitness environments often involve exertion, competition and public attendance. AED access should be practical and fast.
Consider AED placement near:
- Main playing fields
- Gyms and training rooms
- Clubhouses
- Pool decks
- Reception areas
- Event or spectator areas
For outdoor sport, check whether the AED, cabinet and storage location can tolerate heat, rain, dust and regular public access.
AEDs for Community Groups and Public Venues
Community halls, clubs, churches, libraries, shopping areas and public venues may host people of all ages. An AED in these settings should be easy to locate and simple for a bystander to use.
Useful considerations include:
- Public access signage
- Clear instructions
- After-hours access
- Volunteer training
- Central location
- Regular maintenance checks
- Protection from theft, weather or damage
For community groups, it is often worth assigning more than one person to check the AED so maintenance does not depend on a single volunteer.
Where Should an AED Be Placed?
An AED should be placed where it can be reached quickly. A central, visible location is usually better than a locked office, storage room or back-of-house area.
Good AED Locations May Include:
- Reception areas
- First aid rooms
- Near main entrances
- Beside sports fields or courts
- Near gyms or pool areas
- In staff areas with clear signage
- Near high-risk work zones
- In vehicles used for remote or mobile work
The location should be included in staff induction, emergency procedures and site maps where appropriate.
What Accessories Should You Buy With an AED?
An AED should usually be purchased with the accessories needed to store, identify and use it properly.
Useful AED accessories may include:
- Wall cabinet
- Outdoor cabinet where required
- AED signage
- Spare adult pads
- Child pads or paediatric key where required
- Replacement battery
- Carry case
- Rescue kit with scissors or trauma shears
- Razor for chest hair removal where included
- Gloves
- CPR face shield or mask
- Towel or wipes for drying the chest
- Inspection tag or maintenance log
Some AEDs include a rescue kit, while others require accessories to be purchased separately.
AED Maintenance: What Needs to Be Checked?
An AED should be checked regularly to make sure it is ready for use. Many devices perform self-tests and show a status indicator, but a responsible person should still inspect the unit.
AED Maintenance Checklist
- Is the AED in its correct location?
- Is the AED visible and accessible?
- Is the status indicator showing ready?
- Are the pads in date?
- Is the battery in date?
- Is the cabinet clean and undamaged?
- Are scissors, gloves, razor and face shield present if included?
- Is signage visible?
- Has the AED been used, moved or tampered with?
- Has the check been recorded?
Monthly checks are a practical baseline for many workplaces and community sites, with additional checks after events, incidents or relocation.
Do You Need Training to Use an AED?
AEDs are designed to guide users through the emergency process, but CPR and AED training is strongly recommended. Training helps people act faster, recognise cardiac arrest and understand how CPR and defibrillation work together.
Training should cover:
- Recognising cardiac arrest
- Calling emergency services
- Starting CPR
- Sending someone to retrieve the AED
- Turning on the AED
- Applying pads correctly
- Following shock or no-shock prompts
- Continuing CPR after AED instructions
- Keeping bystanders clear during shock delivery
For workplaces, schools and clubs, training should be repeated regularly enough that staff and volunteers remain confident.
Common AED Buying Mistakes
Choosing Only by Price
The cheapest AED may not offer the best value if pads, batteries or support are difficult to access later.
Forgetting Replacement Pads and Batteries
AED pads and batteries expire. Check ongoing consumable costs before buying.
Hiding the AED Away
An AED should be easy to find quickly. If it is locked away or poorly signed, it may not be reached in time.
Not Considering Child Use
Schools, childcare centres, family venues and community groups should check paediatric capability before buying.
Ignoring the Environment
An AED stored outdoors, in a vehicle or in a dusty workplace may need more durable protection than one kept inside an office.
Not Assigning Maintenance Responsibility
Someone should be responsible for checking the AED, recording inspections and replacing pads or batteries before they expire.
Buying Without Training
The AED may guide users, but training builds confidence and reduces hesitation during a real emergency.
How Many AEDs Does a Site Need?
There is no single number that suits every site. The answer depends on the size, layout, number of people, risk profile and how quickly the AED can be retrieved.
Consider more than one AED if:
- The site is large or spread across multiple buildings.
- There are multiple floors.
- There are separate sports fields or outdoor areas.
- Access routes may be blocked or slow.
- The site has remote or isolated work areas.
- Large events are held on site.
- The AED would take too long to retrieve from some areas.
A useful test is to walk from the likely emergency area to the AED and back. If that takes too long, placement or quantity should be reviewed.
