How Private Health Insurance Works in Australia
Why Private Health Insurance Matters
Australia's world-class Medicare system covers treatment as a public patient in public hospitals and subsidises visits to GPs and specialists. However, private health insurance (PHI) gives you choice: choose your own doctor, skip public waitlists, and access private hospitals. It also helps you avoid the Medicare Levy Surcharge and Lifetime Health Cover loading.
Hospital Cover vs Extras Cover
Private health insurance in Australia is split into two main types:
- Hospital cover: covers in-hospital treatment as a private patient. Tiers: Gold, Silver, Bronze, Basic (more on this in our hospital cover guide).
- Extras cover (also called "general treatment" or "ancillary"): covers out-of-hospital services like dental, optical, physiotherapy, and chiro. See our extras cover guide.
You can buy hospital-only, extras-only, or a combined policy ("hospital + extras").
How Premiums Are Set
Health fund premiums are community-rated: the same policy costs the same regardless of your age, gender, or health status (with some age-based discounts for young adults). Premiums generally rise every April 1st (the annual price review).
Factors that affect your premium:
- Level of cover: Gold hospital policies cost more than Bronze.
- Excess: Choosing a higher excess lowers your monthly premium.
- State: Some states have state-specific levies or arrangements.
- Age: Young adult discounts (often 10 — 20% off) are available for ages 18 — 29.
- Single vs couples/family: Family policies cover dependants under 18 (or 25 if full-time students).
Medicare and PHI: How They Work Together
When you're treated as a private patient in a hospital, Medicare pays 75% of the Medicare Benefits Schedule (MBS) fee, and your health fund covers the remaining 25% plus any gap: depending on your policy and whether the doctor participates in gap cover arrangements.
For extras, there's no Medicare component: you pay the provider and claim back from your fund up to annual limits.
Key Terms to Know
- Annual limit: The maximum your fund will pay per person per year for a specific extras service.
- Waiting period: Time you must wait before claiming (e.g. 2 months for general dental, 12 months for pre-existing conditions).
- Gap: The difference between a doctor's fee and what Medicare + your fund pay.
- Excess: The amount you pay toward your hospital stay before your fund covers the rest.
- Co-payment: A fixed amount you pay each day in hospital (instead of a single excess).
Do You Need Private Health Insurance?
Not everyone needs it. If you're happy with public hospital care and don't need ambulance cover, you may choose to go without. However, higher-income earners pay the Medicare Levy Surcharge (MLS) unless they hold appropriate hospital cover, and those over 30 may face Lifetime Health Cover loading if they delay taking out hospital cover. Read our guide on the Medicare Levy Surcharge and Lifetime Health Cover for details.
The 2026 Premium Picture
Premiums are reviewed every year on 1 April. For 2026, the Australian Government approved an average rise of 4.41% — the largest increase since 2017, and up from 3.73% in 2025 (per the Department of Health and Aged Care). Increases vary by fund: NIB rose about 5.47%, Medibank 5.10%, HCF 4.96% and Bupa 4.80%, while HBF rose just 2.15% and GMHBA 1.98%. The main driver is the rising cost of hospital and medical services, which grew about 5% in the last financial year. The practical takeaway: if you have not reviewed your policy since April 2026, your premium has almost certainly gone up — and comparing funds now could save you more than in recent years.
How the Government Rebate Lowers Your Premium
The Private Health Insurance Rebate is an income-tested government contribution that directly reduces what you pay. From 1 July 2026, a single earning $101,000 or less (or a family on $202,000 or less) in the base tier receives 24.118% of their premium back if the oldest person on the policy is under 65 — rising to 28.139% for ages 65–69 and 32.158% for 70 and over. The rebate is usually applied automatically as a discount on your premium, or you can claim it through your tax return. Because the rebate tiers track the Medicare Levy Surcharge thresholds, your eligibility changes as your income changes — so it is worth rechecking after a pay rise or a change in family circumstances.
A 5-Minute Decision Checklist
- If you earn over $101,000 as a single (or $202,000 as a family), check whether you need hospital cover to avoid the Medicare Levy Surcharge.
- If you are 30 or older without hospital cover, work out your Lifetime Health Cover loading before delaying further.
- Decide between hospital-only, extras-only, or combined — based on services you actually use.
- Set your excess deliberately: a higher excess means a lower premium.
- Re-compare at least once a year, especially after the April price review.
