A first aid certificate in Australia lasts three years. That’s the short answer. But there’s a bit more to it. Not all components of your certification expire at the same time, and letting the wrong one lapse can leave you out of compliance faster than you’d expect.

The part most people miss is CPR. Even though your full first aid certificate is valid for three years, the CPR part needs to be renewed every 12 months. It’s a short course, usually just a few hours, but it’s mandatory. It’s one of the most commonly overlooked renewal requirements in Australian workplaces.

For employers, this matters a lot. Having a team member whose certificate has expired is a WHS compliance problem. For individuals, an expired certificate can affect your ability to work in roles that require current first aid training, from childcare and construction to hospitality and aged care.

This guide breaks down exactly how long a first aid certificate lasts, what needs to be renewed and when, and how to make sure you never get caught out.

What Is a First Aid Certificate and Why Do You Need It?

A First Aid certificate confirms that you’ve been trained to respond to a range of emergency situations, including injuries, medical incidents, and life-threatening events.

This includes practical skills such as:

• Performing CPR
• Managing bleeding and wounds
• Responding to asthma, anaphylaxis, and cardiac events
• Providing initial care until emergency services arrive

For many roles, this isn’t optional. Employers rely on staff being able to respond quickly and appropriately in real situations — not just hold a certificate.

How Long Does a First Aid Certificate Last in Australia?

A First Aid certificate (Provide First Aid – HLTAID011 and Childcare First Aid – HLTAID012) is valid for 3 years from the date of completion.

Unlike some other work licences, there’s no flexibility here. Once you pass the 3-year mark, your certification is no longer considered current, and you’ll need to redo your First Aid Training.

To make this clear in practical terms:

• Your certificate is accepted for 3 years after you complete the course
• After 3 years, it is considered expired for workplace purposes
• There is no automatic renewal — you must complete training again

This is the standard applied across most industries in Australia.

The CPR Requirement

This is the part that causes the most confusion. Even though your First Aid certificate lasts 3 years, your CPR (HLTAID009) component must be updated every 12 months.

If your CPR is out of date, most employers will simply ask you to complete a CPR refresher course before you start work. When you’re asked to provide a First Aid certificate, employers aren’t just looking for the document — they’re checking whether it’s current.

In most cases, they will look at:

• The issue date of your First Aid certificate (within 3 years)
• The CPR completion date (within 12 months)
• Whether the course was completed through a recognised training provider

If any of these don’t meet requirements, you may be asked to update your training before starting work.

What Happens If Your Certificate Expires?

If your First Aid or CPR certification is out of date, it can affect your ability to work. Common outcomes include:

• Delays in starting a new job
• Being unable to meet compliance requirements
• Employers requesting immediate retraining

In industries like aged care, childcare, mining and construction, this can mean missing out on shifts or roles altogether.

How to Renew or Update Your Certification

Getting up to date and compliant with your First Aid qualifications is straightforward, depending on what certificate has expired:

• If your CPR certificate is expired and over 12 months old: complete a CPR refresher course
• If your First Aid certificate is expired and over 3 years old: complete the First Aid course again

Our First Aid courses are designed to be completed effectively and efficiently, so you can regain compliance without hassle or disruption.

Do Requirements Change Between Industries?

The core timeframes remain the same, but how strictly they’re enforced can vary depending on the job.

You’ll almost always need current certification in:

• Aged care and disability support
• Childcare and education
• Healthcare and community services
• Mining and Remote Work

It’s also commonly required in:

• Construction and trades
• Hospitality and public-facing roles

In higher-responsibility environments, there is typically zero flexibility. Your certification must be fully up to date.

Frequently Asked Questions

Got questions about first aid certificate validity in Australia? Here are the answers to what most people want to know.

Do First Aid certificates expire in Australia?

Yes, they do. A First Aid certificate is valid for three years, and the CPR component expires after just 12 months. These are two separate expiry timelines, and both matter. A lot of people assume their full certificate covers everything until the three-year mark. But if your CPR has lapsed within that period, your overall certification won’t be accepted by most employers.

How long is a First Aid certificate valid for?

A First Aid certificate in Australia is valid for three years from the date you completed the course. After that, you’ll need to retake it, you can’t simply extend or top up an expired certificate. The good news is that renewal courses are generally shorter than the original, since you’re refreshing existing knowledge rather than starting from scratch.

Can I still use my certificate if CPR has expired?

No. If your CPR certification has lapsed, your First Aid certificate is generally not considered current, even if the three-year expiry date hasn’t been reached yet.

Employers in industries like construction, childcare, aged care, and hospitality will check both expiry dates, not just the certificate itself. Turning up to a role with an expired CPR component is the same as turning up with no valid certification at all.
