Telling Family, Work and Others About Your Diagnosis in Australia
After a serious diagnosis, the question of who to tell — and when — can feel almost as difficult as the diagnosis itself. In most situations you are not legally required to disclose anything to anyone. This guide covers what you're actually obliged to share, and with whom. If you'd rather have a plan built around your situation, answer a few questions and we'll build one around you →
The starting point: disclosure is your choice
There is no general legal obligation to disclose a medical diagnosis to your employer, your family, your friends, or most other people in your life. Your health information is yours. The Privacy Act 1988 (Cth) classifies health information as sensitive information — the highest category of protection under Australian privacy law. Organisations covered by the Act (including most employers, insurers, banks, and government agencies) cannot collect, use, or disclose your health information without your consent, except in narrow circumstances defined by law.
Several Australian states and territories also have their own health records legislation — including the Health Records Act 2001 (VIC), the Health Records and Information Privacy Act 2002 (NSW), and the Health Records (Privacy and Access) Act 1997 (ACT) — which may provide additional protections depending on where you live and who holds the information.
The question of who to tell is therefore primarily a practical and personal one, not a legal one — with a small number of well-defined exceptions.
Telling your employer
You are not required to tell your employer your diagnosis. If you need to take leave or request adjustments, you need only say that you have a medical condition affecting your ability to work — not what that condition is. "A medical condition" or "a health issue" is legally sufficient in most employment contexts.
If your employer asks for a medical certificate, a GP or treating doctor can provide one confirming your incapacity and expected return to work without naming the diagnosis. Your employer is not entitled to a diagnosis — only evidence of a health condition that explains the absence or the need for adjustments.
Whatever you do share with your employer, they are bound by the Privacy Act not to disclose it further without your consent. If you tell a manager in confidence, that information should not be passed to HR, colleagues, or anyone else without your permission. If you believe your health information has been improperly shared at work, you can make a complaint to the Office of the Australian Information Commissioner (OAIC) at oaic.gov.au or call 1300 363 992.
Safety-sensitive roles — where disclosure may be required
There are occupational contexts where specific disclosure obligations apply — usually where the safety of others depends on the physical or mental fitness of the worker. If your role falls into one of these categories, the obligation is to your licensing or registration body, not necessarily directly to your employer.
- Aviation — pilots, air traffic controllers, and certain other aviation personnel hold medical certificates issued by the Civil Aviation Safety Authority (CASA). A serious diagnosis that affects fitness to fly must be reported to CASA, which may suspend or vary the medical certificate. Contact CASA's Aviation Medicine section.
- Rail and maritime — similar fitness standards apply under the Rail Safety National Law and Marine Safety (Domestic Commercial Vessel) National Law. Check with the relevant national regulator (the Office of the National Rail Safety Regulator, or the Australian Maritime Safety Authority).
- Healthcare registration — registered health practitioners (doctors, nurses, pharmacists, and others registered under the Health Practitioner Regulation National Law) have obligations to notify the Australian Health Practitioner Regulation Agency (AHPRA) if their health impairment may affect their ability to practise safely.
- Heavy vehicle driving — drivers of heavy vehicles holding a commercial licence have medical standards set by Austroads and their state licensing authority. A serious health condition that may affect driving fitness should be disclosed to the licensing authority; your doctor can advise on whether your condition meets the reportable threshold.
- Mining and resources — many mine sites have site-specific fitness-for-work policies requiring disclosure of conditions that affect safety-critical duties. These are typically site policies rather than legislation, but non-disclosure can have employment consequences.
If you are unsure whether your role triggers a disclosure obligation, speak with your union, your professional registration body, or the Fair Work Ombudsman (fairwork.gov.au or 13 13 94) before disclosing — or before deciding not to.
Telling Services Australia
To access income support payments — JobSeeker Payment, Disability Support Pension, or Carer Payment — you will need to provide medical evidence to Services Australia confirming your condition and its effect on your capacity to work. This is a requirement of accessing those payments, not a general disclosure obligation.
Services Australia is bound by the Privacy Act and the Social Security (Administration) Act 1999. Your health information held by Services Australia cannot be shared with your employer or with other private organisations without your consent. It is used only to assess and administer your entitlements.
You can apply for income support and access Services Australia services without your employer, family, or anyone else knowing.
Telling your bank or lender
You are not required to tell your bank or lender about your diagnosis. However, if illness is going to affect your ability to meet repayments, early voluntary disclosure to your lender's hardship team is generally in your interest. Banks operating under the Australian Banking Association's Banking Code of Practice are required to consider hardship applications — but hardship frameworks typically work best before arrears develop, not after.
Contacting your lender's financial hardship team early — before you miss a payment — gives you more options: repayment deferral, interest-only periods, or loan restructuring are easier to negotiate before the account falls behind. You do not need to name your condition; saying you are experiencing a health-related reduction in income is sufficient to open the hardship conversation.
Workers compensation — only if work-related
Workers compensation is relevant only if your condition was caused by, or materially contributed to by, your work — for example, an occupational cancer caused by workplace chemical exposure, or an injury sustained at work. If that applies, you have separate disclosure and reporting obligations to your employer and to your state's workers compensation authority.
Workers compensation schemes are state and territory-based (WorkCover Queensland, icare NSW, WorkSafe Victoria, ReturnToWork SA, and so on). Each has its own notification timeframes and processes. If you believe your illness may be work-related, report it to your employer promptly and contact your state authority to understand your obligations and rights.
For illness or injury that is not work-related, workers compensation does not apply — personal insurance and Centrelink income support are the relevant mechanisms.
Telling your insurer
If you intend to make an insurance claim, you must notify the insurer promptly — most policies have a notification requirement, and delay can complicate a claim.
A separate issue arises around non-disclosure at policy inception. Under the Insurance Contracts Act 1984, you have a duty to disclose information relevant to the insurer's decision to offer cover and on what terms. If you failed to disclose a pre-existing condition when you applied for a policy, the insurer may be able to avoid or reduce the claim, depending on whether the non-disclosure was fraudulent, negligent, or innocent. If you are concerned about this in relation to an existing policy, seek independent legal advice before making a claim — the rules around non-disclosure are technical and fact-specific.
For new policies: you should not apply for new cover after a diagnosis without disclosing it — doing so constitutes non-disclosure and will typically void any future claim.
Telling family
There is no legal framework governing disclosure to family members — this is entirely your decision. The practical questions most people work through are: who needs to know in order to help; how much detail to share and with whom; and when to tell people.
There is no obligation to tell family immediately after a diagnosis. Many people choose to wait until they have more information — a second opinion, a clearer treatment plan, a better understanding of what the diagnosis means — before telling others. Waiting a short time to gather your own thoughts is entirely reasonable.
Some practical considerations:
- Think about who you want practical help from — getting to appointments, managing the household, financial administration — and whether telling them now makes that help possible.
- Consider whether anyone needs to know because it directly affects decisions they're making — a partner, a carer, someone you live with.
- You can tell different people different amounts of information. Telling a colleague you're dealing with a health issue is different from telling a close friend the full picture.
- Once you tell someone, you can't un-tell them — if you're not ready for a conversation, it's fine to wait.
Talking to children and young people
Children generally cope better with honest, age-appropriate information than with sensing that something is wrong but not being told what it is. Most child development guidance suggests that children do better when they are included — at a level suited to their age — rather than shielded from information entirely.
What and how much to say depends on the child's age and developmental stage. Young children need simple, concrete language; older children and teenagers can usually handle more detail and often want it. Most children benefit from being told that their daily life and routines will continue as normally as possible.
Cancer Council Australia — 13 11 20 — has resources specifically for families talking to children about a parent's or family member's cancer diagnosis. Other condition-specific organisations (Heart Foundation, MS Australia, and others) have similar resources for their conditions. Your treating team — specialist, GP, or hospital social worker — can also advise on age-appropriate approaches.
Support for difficult conversations
Deciding what to say, and how, is a skill that most people haven't had to develop before. You don't have to work it out alone.
- Your GP or specialist can help you think through how to frame your diagnosis — what information is important to convey and what language to use. They can also, with your permission, speak directly with family members who need clinical information.
- Hospital social workers are available at most public hospitals and many private ones. They are experienced in supporting patients and families through disclosure conversations and can facilitate family meetings.
- Peer support programs — many condition-specific organisations run peer support programs where you can speak with someone who has been through the same diagnosis. Cancer Council's Cancer Connect program, for example, matches people with trained volunteers who have had similar diagnoses.
- Psychologists and counsellors — some people find it helpful to work through the disclosure question with a mental health professional before having the conversation. This may be covered under a Mental Health Treatment Plan from your GP (which provides a Medicare rebate for up to ten sessions per calendar year).
If you're not ready to tell anyone yet
Not wanting to tell people immediately — including family — is a completely valid response to a diagnosis. You may need time to process the information yourself before you can help others process it.
Most support services, financial assistance, and medical treatment can be accessed without family members knowing. Services Australia, your super fund, your insurer, your bank's hardship team, and your treating specialists all operate under confidentiality obligations. You can take practical steps — applying for income support, checking your insurance, arranging legal documents — without anyone else knowing unless you choose to tell them.
If you want to speak with someone confidentially before deciding who to tell, your GP is a good starting point. Lifeline (13 11 14) and Beyond Blue (1300 22 4636) offer free, confidential support for people working through difficult situations.
