Is there a magic number of sick days you can take before a medical certificate becomes mandatory? The short answer: no — Australian law sets no minimum number of "free" sick days. Under the Fair Work Act, your employer can ask for evidence for any absence, even a single day. In practice, though, most workplaces give you one or two days of self-certified sick leave before a certificate is expected.
This guide explains what the law actually says, how typical workplace policies work, when a statutory declaration can step in, and what happens if you're asked for evidence and don't provide it.

Get a Certificate OnlineThe Quick Answer
- There is no legislated number of sick days you can take without a certificate. The Fair Work Act doesn't say "the first two days are certificate-free".
- Your employer can request evidence for any sick day — including day one — provided the request is reasonable in the circumstances.
- In practice, many workplaces allow 1–2 days with just a phone call, text or email before a certificate is required. It comes down to your award, enterprise agreement or company policy.
- A statutory declaration is a legal alternative in many cases — unless your award or agreement specifically requires a medical certificate.

What the Fair Work Act Actually Says
If you're a permanent employee, you accrue paid personal/carer's leave — 10 days per year for full-time staff, pro-rata for part-timers. When you take this leave, the Fair Work Act lets your employer require evidence that would satisfy a reasonable person that the leave was taken for a genuine personal illness or carer's reason.
The Act gives two standard examples of acceptable evidence:
- A medical certificate from a registered health practitioner
- A statutory declaration
Crucially, the law doesn't attach that evidence requirement to a minimum number of days. Technically, an employer could ask for proof for a single day off. What stops most employers from doing that is the word reasonable — demanding a doctor's visit for every sniffle generally wouldn't be considered reasonable, and Fair Work expects employers to apply evidence requirements consistently and sensibly.
Common Workplace Rules: The 1-Day and 2-Day Conventions
Your award or enterprise agreement can make these rules binding, so check your employment contract, award or HR policy — it's the single most reliable answer to "how many days can I take?".
One more trap to know about: some policies count episodes, not just days. Three separate one-day absences in a month can trigger a certificate requirement even though no single absence was long.
The Statutory Declaration Alternative
If you're sick for a day or two and can't easily get to a doctor, a statutory declaration can be a legitimate way to evidence your absence. You're declaring that you (or the person you cared for) were genuinely unwell — it's a serious legal document, so it should only be used when that's true.
A couple of things to check first:
- Your award or enterprise agreement wins. Some awards state that a statutory declaration alone is not sufficient evidence — in those cases a medical certificate is the only option.
- Your employer still gets the final say on whether a stat dec is reasonable evidence in your situation. If they accept one, that's generally the end of it.
- Repeated stat decs raise flags. If you're regularly unwell or taking frequent single days, a pattern of declarations instead of certificates is something HR may question.
How Much Sick Leave Do You Actually Have?
- Full-time permanent employees: 10 days of paid personal/carer's leave per year (about 7.6 hours per fortnight of service, accruing progressively)
- Part-time employees: the same entitlement, pro-rata to hours worked
- Casual employees: no paid personal leave — but you can access unpaid carer's leave (2 days per occasion) with reasonable evidence
- Unused leave rolls over year to year and is paid out on termination in most cases
There's no separate "sick days without a certificate" pool — the evidence question is about proof, not a different type of leave.
What Happens If You Don't Provide a Certificate When Asked?
If your employer reasonably requires evidence and you don't supply it, a few things can happen:
- The leave may be treated as unpaid — until you provide the evidence
- You may be asked to attend a return-to-work conversation, especially if absences form a pattern
- Repeated non-compliance can lead to disciplinary action, potentially including termination in serious cases
In most cases you'll get a chance to provide the documentation first — but ignoring a reasonable request is risky. If you're genuinely too unwell to obtain a certificate on the day, contact your employer, explain, and arrange the certificate as soon as you're able. A same-day telehealth certificate obtained from your lounge room removes the problem entirely.
You Don't Have to Disclose Your Diagnosis
A medical certificate needs to confirm that you were unfit for work and the period of unfitness — not why. Employers are not entitled to your diagnosis, test results or clinical details. If a certificate includes sensitive health information, you can ask your doctor to issue a certificate limited to fitness for work only.
When It's Worth Getting a Certificate Anyway
Even if your first two days are certificate-free, consider getting one when:
- Your illness will clearly run longer than your self-certified allowance
- You've already had recent absences and a pattern is building
- Your employer's policy is ambiguous or your manager has asked questions before
- You want the absence formally documented for your own records

Frequently Asked Questions (FAQ)
Common questions about sick leave and medical certificates.
Can my employer ask for a medical certificate for just one sick day?
Yes. The Fair Work Act sets no minimum number of days before evidence can be required — your employer can ask for evidence for any absence, provided the request is reasonable in the circumstances. In practice, most workplaces only require a certificate from the second or third day, but check your award, agreement or policy.
Can I use a statutory declaration instead of a medical certificate?
Often, yes — a statutory declaration is one of the standard forms of evidence under the Fair Work Act. However, some awards and enterprise agreements require a medical certificate specifically, and your employer can decline a stat dec if a certificate is a reasonable ask in your situation.
How many sick days do I get per year in Australia?
Full-time permanent employees accrue 10 days of paid personal/carer's leave per year; part-timers accrue the same pro-rata. Casual employees don't receive paid personal leave but can take unpaid carer's leave with reasonable evidence. Unused leave carries over from year to year.
What happens if I don't provide a medical certificate when asked?
Your employer can treat the leave as unpaid until evidence is provided, and repeated non-compliance can lead to disciplinary action. If you're too unwell to get a certificate on the day, let your employer know and arrange one as soon as you can — a same-day online certificate is usually enough to resolve it.
Can I get a medical certificate online for yesterday or today?
Yes. At NewTeleDoc Medical, AHPRA-registered GPs assess you by telehealth and can issue a medical certificate for the period you're unfit for work — including same-day certificates, with certificates available from $15.
