How to Tell If a Defibrillator Is Mandatory for Your Office
Last Updated: October 25, 2026
Quick Summary
A defibrillator mandatory rule does not cover every office in Australia; no blanket national law requires an AED in ordinary offices. South Australia is the only jurisdiction with a dedicated public-building AED law, while elsewhere general work health and safety first aid duties apply. Every employer must still assess cardiac risk and provide what is reasonably practicable.
- South Australia is the only jurisdiction with a dedicated public-building AED law.
- Everywhere else, the obligation flows from general work health and safety first aid duties.
- The first aid duty requires equipment and trained staff based on a risk assessment, not a fixed list.
- An AED should reach a casualty within a couple of minutes, ideally less.
- Check your AED at least monthly for battery, pad dates and a ready status indicator.

Is a Defibrillator Mandatory for Offices? The Short Answer
No, a defibrillator mandatory rule does not cover every office in Australia.
That distinction trips up most office managers.
Below, we break down where the legal requirements actually bite, how to work out whether your office is caught, and what to do if it isn't.
"Not mandatory" is not the same as "not needed." Whether a defibrillator is mandatory for offices has two answers, legal and practical. You need both.
Workplace Defibrillator Requirements Australia: State by State
Workplace defibrillator requirements Australia-wide are not set by one national rule.
For most private offices, no state law compels an AED; mandates tend to cover public and prescribed buildings, not leased office suites.
Here is the current picture, jurisdiction by jurisdiction. Treat it as a starting point and confirm the live position with the relevant regulator, because these laws are amended from time to time.

Specific AED law to check |
Who usually carries the duty |
|---|---|---|---|
South Australia |
No for ordinary offices; yes for certain public buildings |

Two patterns stand out. South Australia is the only jurisdiction with a dedicated public-building AED law. Everywhere else, the obligation flows from general work health and safety first aid duties, so the practical answer for most offices is 'not legally mandatory, but risk-assessed.'
South Australia's Public Building AED Rules
South Australia is the state to watch. Its legislation requires automated external defibrillators in certain public buildings, the clearest example of a workplace defibrillator requirement in the country.
The rules target designated public buildings rather than ordinary offices, so the trigger is usually the building's classification and public access, not the fact that someone works there.
That division of responsibility is where most disputes start.
How to Work Out Whether Your Office Is Covered
Start with a short decision sequence.
- Which state or territory is the office in? This determines which statute applies. If you have offices in more than one jurisdiction, assess each site separately.
- Is the building a public or prescribed building under local law? Check the building's classification and whether members of the public can enter it. A private office suite inside a public facility is the classic edge case.
- Who owns the obligation, you or the building owner? Look at the lease and any building management arrangements. If the duty sits with the owner, get the device, location and maintenance schedule confirmed in writing.
- Does a risk assessment point to an AED anyway? Even where no specific law applies, the general first aid duty can make an AED a reasonable control. This is the fallback that applies to every office in every jurisdiction.
If you can't answer all four, you don't yet know your position.
Your Employer Duty of Care and Safe Workplace Obligations
Every employer has a duty of care to provide a safe working environment, and that duty is 'reasonably practicable.' This is where the defibrillator question gets practical, because the duty applies even when no specific AED law does.
The mechanism is the first aid duty in the model work health and safety regulations. Those regulations require a business to provide first aid equipment, facilities and trained staff, and to base that provision on a risk assessment rather than a fixed shopping list.
What 'Reasonably Practicable' Actually Means in Practice
The phrase is often treated as a vague escape hatch. It isn't. Regulators expect an employer to weigh the likelihood and degree of harm, what is known about the risk, and the availability and cost of controls.
That combination tends to push offices toward providing an AED where the risk assessment identifies a meaningful exposure. The duty does not require perfection, but it does require a defensible process.
How the Duty Interacts With the Absence of a Specific Mandate
A common misconception is that 'not mandatory' means 'no obligation.' A specific AED law creates a clear requirement for covered buildings; the general duty of care creates a broader, risk-based obligation for every employer regardless of whether a specific AED law exists.
An office in a jurisdiction with no AED mandate can still be exposed if a cardiac arrest occurs and the employer had not considered whether an AED was a reasonable control.
What to Document
A defensible record usually captures:

- The risk assessment itself, including workforce size, site location, ambulance response expectations, physical demands and public access.
- The controls considered and the reasons for the decision reached.
- The first aid equipment and trained responders actually provided.
- The review date, because risk assessments are living documents and circumstances change.
If the assessment points to an AED, the next step is to plan placement and maintenance so the device is actually ready when it is needed.
Running a Workplace AED Risk Assessment
A workplace AED risk assessment is a structured look at how likely a sudden cardiac arrest is on your site and how quickly help could reach someone. It turns a vague worry into a defensible decision.
Work through these factors:
- Workforce size and age profile: more people, and older teams, raise the odds.
- Site location and ambulance response: remote or slow-response sites carry more risk.
- Physical demands: strenuous roles raise cardiac strain.
- Public access: if members of the public visit, your exposure grows.
Record the findings. A documented assessment is what shows a regulator you took the duty seriously.
How Many AEDs Does a Workplace Need?
There is no fixed national formula for how many AEDs a workplace needs. The right number depends on your layout, travel distance for a responder, and how many people are on site.
A practical rule is response time. An AED should reach a casualty within a couple of minutes, ideally less. For a single-floor office, one well-placed unit usually covers the floor.
Use this simple guide:
Situation |
Suggested AEDs |
Why |
|---|---|---|
Small single-floor office |
1 |
One central unit covers the floor |
Multi-level office |
1 per floor |
Keeps retrieval time short |
Large or spread-out site |
1 per zone |
Distance is the deciding factor |
Site with public access |
1 near entry |
Serves visitors and staff |
Why an Office Should Have an AED Even When It Isn't Required
The case for a voluntary AED is simple: sudden cardiac arrest can happen to anyone, anywhere, and early defibrillation saves lives.
Modern AEDs are built for laypeople: clear voice prompts, automatic rhythm analysis, and a shock only when one is needed. You cannot shock someone who doesn't need it.
If staff are worried about using one wrong, in practice, the biggest barrier is confidence, not complexity.
Workplace AED Maintenance Checklist
A defibrillator that isn't ready is worse than none at all, because people assume it will work. A maintenance checklist keeps yours in working condition.
Run through this at least monthly:
- Check the status indicator shows ready
- Confirm the battery is in date and not expired
- Check electrode pads are sealed and in date
- Confirm the cabinet or bracket is secure and accessible
Watch out: expired pads and flat batteries are the most common failures found at inspection. Diarise replacement dates so they never lapse.
Choosing and Installing Your Office AED
Choosing an office AED comes down to ease of use, battery life and mounting. A fully automatic unit removes the decision about pressing the shock button, which suits workplaces with untrained staff.
Placement matters as much as the device. Put it somewhere visible, unlocked, and reachable within seconds, not locked in a manager's office. Signage should make it obvious.
We stock the Defibtech Fully Automatic AED Cabinet Bundle, which pairs a Lifeline AUTO AED with an alarmed wall cabinet, rescue kit, carry bag and 3D sign. You can browse the cabinet bundle to see what's included.
Frequently Asked Questions
Is it a legal requirement to have a defibrillator at work?
It depends on where the workplace is and what it does. No single national rule makes an AED compulsory in every office. South Australia has specific legislation covering certain public buildings, and some other states and territories impose AED conditions on particular facilities and activities. Elsewhere, the general work health and safety duty to provide a safe workplace can still make an AED reasonably practicable, especially where a risk assessment identifies cardiac emergency as a credible risk. Check the law that applies in your state or territory before deciding.
Can an employer be required to provide an AED after a workplace risk assessment?
Yes, in practice. The duty to provide a safe working environment is risk-based, so a documented workplace AED risk assessment can create an obligation even where no specific AED law applies. Factors that raise the risk include a large workforce, public visitors, remote or isolated sites, long emergency response times, and staff with known cardiac conditions. If the assessment shows early defibrillation is reasonably practicable, an employer should act on it and record the reasoning.
Who can use a defibrillator in an emergency?
Anyone can use an AED. Modern units give clear voice prompts and only deliver a shock if the rhythm requires it, so a trained responder is helpful but not a precondition for use. Good practice is to train a group of staff in CPR and AED operation, make the unit easy to reach, and register its location with emergency services so callers can be directed to it. In an emergency, call triple zero, start CPR and send someone for the AED.
How often should a workplace AED be checked?
Run a visual readiness check monthly and a fuller inspection quarterly. The monthly check should confirm the status indicator shows ready, the battery has not expired, electrode pads are in date and sealed, and the cabinet or signage is intact. Record each check in a log. Defibtech units such as those stocked by PFA Shop run automatic daily, weekly and monthly self-tests, but a person still needs to confirm the visible status light and consumable dates.
Working out whether a defibrillator is mandatory for your office is really a question of risk, not just law. The safest approach is to assess your site, document your decision, and put a ready AED within reach. PFA Shop supplies automated external defibrillators, AED cabinets and accessories, plus the first aid gear to match, so you can set up a complete emergency response. Get started with PFA Shop and give your team a defibrillator that's ready when it matters.
