Choosing a defibrillator (AED) is one of the most important safety decisions an organisation or individual can make. Whether you're purchasing your first device, upgrading an existing unit, or replacing one nearing the end of its service life, understanding the differences between models is essential to making the right call.
At First Aid Supplies Australia, we're committed to helping you make an informed, confident decision. Below, we compare key AED models objectively — so you can find the best fit for your environment and needs.

Why Owning a Defibrillator Matters
Early Intervention Saves Lives
Sudden Cardiac Arrest (SCA) can strike anyone, at any time — including people with no prior history of heart conditions. Survival rates drop by up to 10% for every minute that passes without defibrillation. When used promptly alongside CPR, an AED dramatically increases a patient's chance of survival in the critical minutes before emergency services arrive.
Legal and Ethical Responsibilities
Businesses and public facilities across Australia are increasingly expected — and in some cases required — to have appropriate first aid measures in place, particularly in high-traffic or higher-risk environments. Providing a safe environment is both a legal obligation and an ethical commitment to your staff, clients, and visitors.
Peace of Mind
Beyond compliance, having an AED on-site means your team can respond immediately in an emergency. It signals a proactive, caring approach to health and safety — reassuring for employees, customers, and community members alike.
Key Considerations Before You Buy
Not all defibrillators are created equal. Here's what to evaluate before committing to a model.
1. Ease of Use and Training Requirements
An AED should be accessible to anyone in an emergency, not just trained medical professionals. Look for:
- Clear audio prompts — step-by-step voice guidance is critical under pressure
- Visual indicators — diagrams and lights to guide pad placement and shock delivery
- Automatic vs. semi-automatic — fully automatic models deliver the shock without user input; semi-automatic models require the user to press a button once advised
- Shock delivery capacity — the Australian Resuscitation Council recommends a minimum of 200 joules, with escalation up to 360 joules if lower doses are ineffective
2. Durability and Environmental Suitability
Consider where the device will be located — a school gym, outdoor sports facility, or industrial site all have different demands:
- Rugged construction — resistance to drops, impact, and vibration
- IP rating — a higher Ingress Protection rating means better resistance to dust and moisture
3. Maintenance and Ongoing Costs
Ownership doesn't end at purchase. Factor in:
- Battery life — longer-lasting batteries with built-in self-tests reduce maintenance burden
- Pad and battery replacement — check frequency and cost of consumables
- Warranty — coverage periods and inclusions vary significantly between manufacturers
4. Total Cost of Ownership
A lower upfront price isn't always the best value. Factor in long-term costs including replacement parts, warranty coverage, and maintenance requirements. Some premium models offer a lower total cost of ownership over their lifespan.
