How Long Is a Medical Certificate Valid in Australia? (1-Day, 2-Day & Longer)
A plain-English guide to how medical certificate validity works under the Fair Work Act — and how a $14.95 flat standard fee covers your choice of 1 or 2 days.
A medical certificate in Australia doesn’t expire — it’s valid for the specific dates a GP certifies. Most short-term absences are 1 or 2 days, and under the Fair Work Act 2009 a certificate from an AHPRA-registered GP is accepted evidence. Doctors Note Australia covers a 1- or 2-day standard certificate for a flat $14.95, reviewed within 24 hours.
What “valid” actually means
A medical certificate is documentation from an AHPRA-registered practitioner confirming you were assessed and found unfit for work or study on specific dates. Under the Fair Work Act 2009, an employer may ask for “evidence that would satisfy a reasonable person” before approving paid personal (sick) or carer’s leave — and a certificate from a registered GP meets that standard.
Importantly, a certificate does not carry an expiry date. It is valid for the specific dates the GP certifies — it remains evidence for that date range, full stop.
One flat $14.95 fee for 1 or 2 days
The large majority of short-term absences are one or two days. At Doctors Note Australia, the $14.95 flat standard fee covers your choice of a 1- or 2-day certificate — you select the dates during your application, and a GP reviews them for clinical appropriateness before issuing. One price either way; the dates must be consecutive.

An honest comparison
| Online (Doctors Note) | In-person GP | |
|---|---|---|
| Speed | Apply from home, reviewed within 24 hours | Book appointment, travel, wait |
| Cost | $14.95 flat (1 or 2 days) | Often bulk-billed (free with Medicare), or a gap fee |
| Verification | Unique reference + QR code | Paper certificate |
| Best for | Straightforward short-term absence | Complex or ongoing conditions needing examination |
Both are legitimate. A free bulk-billed GP visit is the right call for anything complex or ongoing. For a straightforward short-term absence, the online option is reviewed by an AHPRA-registered GP within 24 hours and arrives with employer verification built in.
Frequently asked questions
What if I need 3 or more days?
Our standard online certificate covers up to 2 consecutive days. For longer or ongoing situations, an in-person GP review is the appropriate setting — Dr Walia will tell you if that’s the case rather than issue something inappropriate.
Is the certificate verifiable?
Yes. Every certificate carries a unique reference and QR code linking to an independent verification page, so your employer can confirm it in seconds.
Can my employer reject it because it’s online?
No — not solely because it was issued online. Provided it is from an AHPRA-registered GP and meets the Fair Work Act “reasonable person” standard, it is valid evidence.
Does a medical certificate expire?
It does not expire — it certifies specific dates and stays valid as evidence for those dates.
