A defibrillator is only as reliable as its last service. In Australia, automated external defibrillators (AEDs) are increasingly required in workplaces, schools, sporting clubs, and public spaces — but owning one is only half the equation. Regular, documented servicing is what ensures your device will actually deliver a life-saving shock when it matters most.
This guide covers everything Australian organisations need to know about AED maintenance: what's involved, how often it's required, who is responsible, and how to stay compliant with state WHS regulations. Whether you manage a single unit in a small office or a fleet across multiple sites, this is your reference point.
For a broader overview of which AED is right for your organisation before you think about servicing, see our Top Defibrillator Models Compared guide and our full range of Defibrillators (AEDs).
Why AED Servicing Is Non-Negotiable
Unlike most medical equipment, an AED sits idle for months or years — and then must perform flawlessly in a cardiac emergency. Battery degradation, expired electrode pads, firmware drift, and physical damage can all silently compromise a device. Studies show that a significant proportion of AEDs checked in public access programs are found to be non-operational, most commonly due to expired consumables or missed maintenance.
Under Australia's Work Health and Safety (WHS) Act and harmonised regulations, employers have a duty of care to ensure that first aid equipment is maintained in good working order. An unserviced AED that fails during a cardiac arrest is not just a tragedy — it is a potential liability.
What Does AED Servicing Include?
A professional AED service typically covers the following checks:
- Battery status and expiry: Confirming the battery holds sufficient charge and has not passed its use-by date.
- Electrode pad expiry: Pads have a shelf life (typically 2–4 years) and must be replaced before expiry.
- Self-test log review: Most modern AEDs run daily or weekly self-tests; a technician reviews the log for any flagged errors.
- Physical inspection: Checking the casing, connectors, and cabinet for damage, moisture ingress, or tampering.
- Firmware update: Ensuring the device is running the latest manufacturer-approved software.
- Accessories check: Verifying that the rescue kit (gloves, razor, CPR mask, scissors) is complete and in date.
- Documentation: Issuing a service record for your compliance file.
How Often Should an AED Be Serviced in Australia?
The general industry standard — and the recommendation of most AED manufacturers — is a full professional service every 12 months. This aligns with the annual inspection cycle recommended under AS/NZS 4360 risk management principles and is consistent with WHS duty-of-care obligations.
In addition to the annual professional service, organisations should conduct monthly visual checks in-house: confirm the status indicator is green (or equivalent ready signal), check that pads and battery are within date, and ensure the device is accessible and undamaged.
Some states and sectors have more specific requirements. South Australia, for example, has legislated AED placement and maintenance obligations for certain venues — see our guide to South Australia's AED Laws for detail.
Who Is Responsible for AED Maintenance?
Under WHS legislation, the person conducting a business or undertaking (PCBU) — typically the employer or organisation — is responsible for ensuring first aid equipment is maintained. In practice, this responsibility is often delegated to a first aid officer, facilities manager, or WHS coordinator.
Key responsibilities include:
- Scheduling and documenting annual professional services.
- Conducting and recording monthly visual inspections.
- Replacing consumables (pads, batteries) before expiry.
- Ensuring staff know the location of the AED and have received basic training.
- Keeping a maintenance log accessible for WHS audits.
AED Consumables: What Needs Replacing and When
The two most commonly replaced AED consumables are electrode pads and batteries. Expiry dates vary by brand and model:
- Electrode pads: Typically 2–4 years from manufacture date. Always check the packaging — expired pads may not adhere correctly or deliver the required energy.
- Batteries: Standby life is typically 4–7 years depending on the model and usage. A battery that has powered multiple shocks will deplete faster.
We stock replacement pads and batteries for all major brands including Defibtech, LIFEPAK, HeartSine, ZOLL, Mindray, and HeartStart. Browse our Defibrillator Batteries range or contact us to confirm compatibility with your specific model.
Keeping a Compliant Maintenance Log
A maintenance log is your evidence of due diligence. It should record:
- Date of each inspection (monthly and annual).
- Name of the person who conducted the check.
- Findings and any actions taken (e.g., pads replaced, firmware updated).
- Next scheduled service date.
- Service provider details for professional services.
Store the log with the device or in your WHS management system. Many organisations also attach a laminated inspection card to the AED cabinet.
