Notify as soon as possible, even after the absence starts
Under Australia's national system, you must tell your employer as soon as possible that you cannot attend work because you are sick or need to provide eligible care or support to an immediate family or household member because of illness, injury or an unexpected emergency. This notice can be given after the absence has already started, for example if you were suddenly hospitalised. You should also indicate how long you expect to be away, if you know. Even a very short absence can be subject to a reasonable request for evidence. A pre-arranged appointment, such as a routine check-up, is not automatically sick leave; it only counts if you are unable to work because of illness or injury, considering the actual circumstances.
If you cannot contact your employer immediately because of your condition, record the time when communication became possible and notify then. Do not invent certainty about a return date; update your employer as soon as the situation changes.
Make a factual notification using the workplace channel
Use the reporting channel your workplace normally uses (such as a phone line, app, or email) and keep a record of the time you sent the notice. In your message, state that you cannot attend, the relevant leave reason (for example, personal illness or caring for a sick family member), and the likely duration if you know it. Avoid giving a precise return date unless you are confident. If your situation changes, send an update.
If you are hospitalised and cannot contact anyone, note when you became able to communicate and notify as soon as possible after that. The notice requirement is about informing your employer, not about providing a full medical history.
Clarify what evidence is needed, without oversharing
When you notify your employer, ask which specific evidence they require, how you can submit it securely, and whether they rely on a particular award or enterprise agreement provision. Common evidence includes a medical certificate or a statutory declaration, but what is 'reasonable' depends on the circumstances, such as the length of absence and the nature of the illness. Keep a copy of the evidence you provide and any responses from your employer.
You do not need to assume that providing your full medical history to your entire team is necessary. You can ask whether a summary or a certificate is sufficient. The employer may request evidence even for a short absence, but the request must be reasonable.
If pay or leave is refused, ask for the specific reason
If your employer refuses to pay sick or carer's leave, or refuses the leave itself, ask for the specific reason. The reason could relate to your eligibility, your available leave balance, the adequacy of your notice, the evidence you provided, or another issue. Compare the stated reason with your own dated record of the notification and evidence. If the issue remains unresolved, seek employment advice from a qualified professional, such as a community legal centre or a union, bringing your records and the employer's response.
Keep any separate issues, such as a roster change or dismissal threat, visible and address them separately. This guide does not diagnose illness, approve every appointment, or decide whether a particular document is sufficient without knowing the circumstances and the applicable industrial instrument.
Hypothetical illustration: notice given, evidence disputed
Suppose you wake up with severe stomach pain and cannot go to work. You send a message through your workplace app at 8:15 am, saying you are unwell, cannot attend, and expect to be away for two days. Your employer replies asking for a medical certificate. You visit a doctor, obtain a certificate, and submit it securely the same day. Later, your employer refuses to pay for the second day, saying the certificate was not 'detailed enough'. You ask for the specific reason and compare it with your records. Is the employer's request reasonable given the short absence and the certificate provided? That is the question you would raise with an adviser, not a conclusion this guide can give.
Next steps if the issue is unresolved
If you have asked for the specific reason and compared it with your records, but the matter is still unresolved, you can seek advice from an employment lawyer, a community legal centre, or your union. Bring your dated notification, the evidence you submitted, the employer's response, and any relevant award or agreement provisions. If you believe the refusal is unlawful, you may also consider lodging a formal complaint with the Fair Work Ombudsman, but this guide does not provide legal advice on the outcome. Always keep your own records securely, and do not share more personal information than necessary.
