Is private health insurance compulsory?
No. Medicare covers most essential medical care for all Australian residents. Private health insurance (PHI) is optional — but there are financial reasons some people should have it, and penalties for waiting too long.
The two main incentives are avoiding the Medicare Levy Surcharge (if your income is above the threshold) and avoiding Lifetime Health Cover loading (which makes premiums more expensive the longer you wait).
What does private health insurance actually cover?
PHI has two separate components. You can buy them together or separately.
🏥 Hospital cover
- ✓ Private hospital admissions
- ✓ Choice of surgeon and specialist in hospital
- ✓ Private room (if available)
- ✓ Shorter wait for elective surgery
- ✓ Gap cover for in-hospital procedures (via known gap / no gap schemes)
Does NOT cover:
- ✗ GP visits
- ✗ Out-of-hospital specialist consultations Learn more →
- ✗ Emergency department as a public patient
🦷 Extras cover (ancillary)
- ✓ Dental (check-ups, fillings, crowns)
- ✓ Optical (glasses, contact lenses)
- ✓ Physiotherapy
- ✓ Chiropractic and osteopathy
- ✓ Psychology (limited sessions)
- ✓ Occupational therapy, speech therapy
Does NOT cover:
- ✗ GP consultations
- ✗ Specialist consultations
- ✗ Pathology or imaging
Common misconception: Private health insurance does not cover your GP visits or your out-of-pocket gap fees for outpatient specialist visits. These are not hospital treatments. The only way to avoid GP gap fees is to see a doctor who bulk bills. Understand gap fees →
Medicare Levy Surcharge (MLS)
An extra tax for higher-income earners without private hospital cover. Current 2026–27 thresholds shown below (in effect from 1 July 2026). Source: privatehealth.gov.au. Thresholds are indexed annually each 1 July.

Family threshold increases by $1,500 for each dependent child after the first (unchanged both years).
The MLS calculation (2026–27): At $110,000 income (above the $105,000 threshold), the 1% surcharge = $1,100/year extra tax. Basic hospital cover for a single adult might cost $1,200–$1,800/year before the PHI rebate — often similar to or less than the surcharge, plus you get the actual cover. For many people above the threshold, getting basic hospital cover makes financial sense even if they never use it.
Lifetime Health Cover (LHC) Loading
If you don't take out hospital cover by 1 July following your 31st birthday, your premiums will be higher — permanently, until you've held cover for 10 continuous years.
Loading is removed after 10 continuous years of hospital cover. Taking out hospital cover before you turn 31 (by 1 July after your 31st birthday) means you'll never face LHC loading.
Age-based discount for 18–29 year olds
The flip side of Lifetime Health Cover loading: some insurers offer a discount of up to 10% on hospital cover premiums for people who take out cover young. It's optional for each fund — check with your insurer — but many participate.
| Age when you take out cover | Discount |
|---|
| 18–25 | 10% |
| 26 | 8% |
| 27 | 6% |
| 28 | 4% |
| 29 | 2% |
| 30+ | Not eligible for a new discount |
Once you have the discount, you keep it until you turn 41. From then it reduces by 2% a year until it reaches zero. It applies to the hospital cover component only (not extras), and doesn't apply to dependents on a family or single-parent policy.

The PHI Rebate — government help with premiums
The government subsidises private health insurance premiums through the PHI rebate. The rebate is income-tested — higher earners get less (or nothing). You can take the rebate as a premium reduction (easier) or as a tax offset at the end of the year.
Rebate tiers and percentages change annually on 1 April. Check your current rebate entitlement at ato.gov.au — PHI rebate thresholds.
Who should consider private health insurance?
💰 Higher income earners (above MLS threshold)
If your income exceeds $105,000 (single) or $210,000 (family) in 2025–26 — rising to $105,000 / $210,000 from 1 July 2026 — compare the cost of basic hospital cover against the MLS. Basic cover often costs less than the surcharge — making it financially rational even without heavy use.
🎂 People approaching 31
Taking out hospital cover before 1 July following your 31st birthday locks in zero LHC loading for life. Even if you don't need it now, the compounding cost of LHC loading (up to 70% extra) makes early entry worthwhile if you plan to ever hold cover.
🎓 People aged 18–29
Signing up now (rather than waiting) can lock in an age-based discount of up to 10% on hospital cover premiums — where your insurer offers it — on top of permanently avoiding LHC loading later. The discount lasts until you turn 41.
🦷 People with high dental or optical needs
Extras cover can provide real value if you need regular dental work, glasses, or physiotherapy. Do the maths — compare your likely annual claims against the premium. Many people with basic needs pay more than they claim back.
🏥 People wanting choice and shorter waits
Hospital cover gives you choice of surgeon, private room (if available), and typically shorter waits for elective procedures like hip replacements, cataract surgery, or colonoscopies compared to the public system.
📉 Lower-income earners under 31 with no health issues
If your income is below the MLS threshold and you're young and healthy, the maths often don't stack up. Medicare provides solid coverage for most needs. The exception: if you're approaching 31, consider getting basic hospital cover before the LHC loading kicks in.
Comparing policies
All private health funds are required to offer the same four tiers of hospital cover: Basic, Bronze, Silver, and Gold. This makes comparison easier. The government's comparison tool at privatehealth.gov.au lets you compare all policies from all funds in one place — it's independent and free.
Watch out for: waiting periods (pre-existing conditions can have 12-month waits), annual limits on extras claims, and gap fees that still apply even with hospital cover for some procedures.
