How Private Health Insurance Works in Australia and How to Compare Policies
Private health insurance in Australia is optional cover that pays towards treatment as a private patient, either in hospital or outside it. You can research how it works, find registered insurers, and compare policies through PrivateHealth.gov.au, the independent information site run by the Commonwealth Ombudsman. This guide is for anyone new to the system or weighing up whether to take out or change cover; it explains the main concepts and the tools the site provides, without recommending a specific policy.
The two parts of a policy: hospital and extras
Most policies are built from two separate covers, and you can usually buy them together or on their own.
- Hospital cover pays towards the cost of treatment as a private patient in hospital. It can cover things like accommodation, theatre fees and some medical costs, depending on the policy.
- Extras cover (also called general treatment) pays towards services outside hospital, such as dental, optical, physiotherapy and similar allied health services.
Because the two are separate, a policy with strong hospital cover may have limited extras, and the reverse. When comparing, check each part against what you actually expect to use.
How the costs are shared
Private health insurance does not usually pay the full bill. Costs are typically split between your insurer, Medicare, and you. The main things to understand:
- Premiums are what you pay for the policy. Premiums change over time, and the site notes premium increases as a topic to follow.
- Excess or co-payment is the amount you agree to pay towards a hospital stay before your insurer contributes.
- Gap is the difference between what your doctor charges and what Medicare plus your insurer pay. Gap cover arrangements and agreement hospitals exist to reduce or remove this out-of-pocket cost for hospital treatment.
- MBS item numbers identify specific medical services. They matter because insurer benefits and doctor charges are often described in relation to these item numbers, so they help you check whether a service is covered.
Key rules and concepts
Lifetime Health Cover
Lifetime Health Cover is a loading that applies if you take out hospital cover later in life. Taking out cover before a certain age (your base day) generally avoids the loading, and the site provides a calculator to work out your base day. This is one of the main reasons people consider taking hospital cover earlier rather than later.
Premium increases
Premiums are not fixed. They are adjusted over time, and the site lists premium increases among its quick-answer topics, so you can check how and when changes apply.
The private health insurance rebate
The Australian Government rebate reduces the cost of complying policies for eligible people. The site covers the rebate as part of how health insurance works; eligibility and the level of rebate depend on factors such as income and age, so check the current rules rather than assuming a fixed amount.
Restricted insurers
Some insurers operate under restrictions, which can affect what they offer. The site includes restricted insurers as a topic, useful if you come across an unfamiliar fund.
Comparing policies and finding insurers
PrivateHealth.gov.au is set up to let you do this in one place:
- Compare policies – use the comparison tool to find policies that match your needs, filtering by the type of cover you want.
- Find insurers – look up policies, contact details and performance information for registered health insurers.
- Check agreement hospitals – confirm whether a hospital has an agreement with your insurer, which affects whether you face a gap.
- Look up gap cover doctors – see which doctors participate in gap cover arrangements.
- Use MBS item numbers – identify services so you can check coverage.
Because the site is run by the Commonwealth Ombudsman, it is independent of the insurers it lists, which makes it a reasonable starting point before you talk to a fund directly.
Where to go for questions and complaints
The Private Health Insurance Ombudsman handles complaints and questions about private health insurance. The site also offers a glossary, brochures, a Medical Costs Finder, and a form to ask a question, so you can clarify a term or a specific situation before or after choosing a policy.
A practical way to decide
- Work out whether you mainly want hospital cover, extras, or both.
- Check your Lifetime Health Cover base day if hospital cover is relevant.
- Use the comparison tool to shortlist policies, then check agreement hospitals and gap cover for the doctors and hospitals you would likely use.
- Confirm the current rebate position and how premiums are changing before committing.
None of this tells you which policy is right for you — that depends on your health needs, income and how you use the system — but it gives you the independent information to make the comparison yourself.
