Around 45% of Australians hold private hospital cover, which means the majority rely entirely on Medicare for their healthcare. For a single person earning $100,000 in 2025-26, going without hospital cover triggers an extra tax penalty of roughly $1,000 through the Medicare Levy Surcharge — often more than the cost of a basic policy. That single number reshapes the entire decision for millions of households.

Medicare covers the essentials: GP visits, public hospital stays, and subsidised medicines through the PBS. But it leaves real gaps — dental, optical, physiotherapy, ambulance transport in most states, and long waits for elective surgery. Private health insurance fills some of those gaps, but at a monthly cost. The question isn’t which system is better. It’s which combination fits your income, your age, and your health needs. Here’s what you actually need to know.
Four Things to Know Before You Decide
The central concept that ties all this together is the Medicare Levy Surcharge. It’s not a fee for a service — it’s an extra tax designed to encourage high-income earners to take out private hospital cover.
What I tend to notice is that most people underestimate how much the tax incentives drive this decision. The MLS alone can make private insurance a net financial gain, not just a health expense.
The Real Cost of Waiting: Thresholds, Penalties, and Cash Trade-offs
The numbers that matter most are the MLS thresholds, the Lifetime Health Cover loading, and the gap between what Medicare pays and what specialists charge. Each one has a direct cash impact on your household budget.

| Income (Single) | Income (Family) | Surcharge Rate |
|---|---|---|
| $97,001 – $113,000 | $194,001 – $226,000 | 1.0% |
| $113,001 – $140,000 | $226,001 – $280,000 | 1.25% |
| $140,001+ | $280,001+ | 1.5% |
Take a 40-year-old earning $120,000. Without hospital cover, the MLS adds 1.25% — that’s $1,500 in extra tax. A basic hospital policy might cost around $1,200 per year. The net result: you save $300 and have private cover. The numbers flip for lower incomes. If you earn $80,000, no MLS applies, and the decision rests entirely on whether you value shorter waiting times and extras cover enough to pay the premiums.
The Lifetime Health Cover loading adds another layer. If you delay hospital cover past July 1 following your 31st birthday, your premium increases by 2% for each year you wait. Join at 40 and you pay a 20% loading for 10 years. On a $1,200 policy, that’s an extra $240 per year — $2,400 over the decade — for no additional benefit. The loading disappears after 10 years, but the money is gone.
Where People Get Tripped Up
Assuming Medicare covers everything
Medicare does not cover most adult dental treatment, glasses or contact lenses, physiotherapy, chiropractic, or ambulance transport in most states. A routine dental check-up costs $150–$300 out of pocket. A set of glasses runs $200–$600. For anyone who uses these services regularly, the lack of cover adds up fast. The Child Dental Benefits Schedule covers basic dental for children up to 17, but adults are on their own.
Buying the cheapest policy without checking exclusions
Basic hospital policies often exclude heart surgery, joint replacements, and pregnancy. You pay the premium but get no benefit if you need one of these common procedures. The government’s Gold/Silver/Bronze/Basic tier system makes this clearer, but many people still grab the lowest price without reading the exclusions. A Silver Plus policy that covers heart, bones, and digestive care is usually the sweet spot for most adults.
Ignoring the Lifetime Health Cover deadline
Turning 31 without hospital cover triggers a permanent loading. What I’d do is mark the calendar. If you’re 29 or 30 and don’t have cover, the cheapest hospital policy you can find before the deadline locks in a base rate without loading. You can upgrade later. The cost of delaying one year is a 2% loading that lasts a decade.
Not reviewing cover annually
Policies change, premiums rise, and your health needs shift. A Gold policy that made sense when you were planning a family is wasted money after the kids are born. An annual review takes 20 minutes and can save hundreds. Use the government’s comparison tool at privatehealth.gov.au to check if your policy still fits.
- Turning 30 or 31 (LHC deadline approaching)
- Income crossing $97,000 (single) or $194,000 (family)
- Planning a pregnancy (12-month waiting period for obstetrics)
- Developing a chronic condition needing regular specialist care
- Your premium increased more than 10% in the last year
Building Your Healthcare Strategy: Medicare, Private, or Both
When Medicare is enough
If your income is below $97,000, you have no chronic conditions, and you’re comfortable with public hospital waiting lists, Medicare alone is a perfectly reasonable choice. No MLS applies, no LHC loading kicks in until you turn 31, and you avoid monthly premiums. The trade-off is that you’ll wait for elective surgery and pay full price for dental and optical. For many younger, healthy Australians, that trade-off makes sense.
When private insurance makes financial sense
Three scenarios tip the scales. First, income above $97,000 — the MLS penalty makes a basic hospital policy cheaper than the tax. Second, approaching 31 — joining before the LHC deadline avoids a permanent loading. Third, planning a family — obstetric cover has a 12-month waiting period, so you need to join before conception. In each case, the numbers favour buying cover.
How to choose a policy
Hospital cover is the priority for most people. It’s what the MLS and LHC rules apply to. Extras cover is separate and optional — only buy it if you actually use dental, optical, or physiotherapy. Compare policies by tier: Gold covers everything (pregnancy, heart, joints), Silver covers most common needs, Bronze covers basic hospital care, and Basic covers very little. A Silver Plus policy that includes heart, bones, and digestive care covers the procedures most people actually need.

| Feature | Medicare | Private Health Insurance |
|---|---|---|
| GP visits | Bulk-billed or subsidised | Not covered (out-of-hospital) |
| Public hospital (public patient) | Free | Not needed |
| Private hospital | Not covered | Covered (depending on policy) |
| Adult dental | Not covered | Covered (extras) |
| Ambulance | Not covered (except QLD/TAS) | Often covered |
| Elective surgery waiting time | Months to years | Weeks to months |
| Cost | 2% levy on income | Monthly premiums |
The mechanics of claiming
For GP visits, present your Medicare card. If the doctor bulk-bills, you pay nothing. If not, you pay the gap and claim the rebate through Medicare. For private hospital treatment, give your health fund details at admission. Medicare pays 75% of the MBS fee, and your insurer covers the hospital costs and the remaining 25% medical gap, depending on your policy. For extras like dental, you pay the bill and claim back a percentage from your insurer, or use a member-direct provider who bills the insurer directly.
2026 rule changes to watch
The Health Transparency Act standardised policy tiers into Gold, Silver, Bronze, and Basic, making comparisons easier. Minimum coverage standards now apply to each tier, so a Bronze policy must cover at least a defined set of services. Senior rebates were increased slightly. These changes don’t alter the fundamental decision, but they make it easier to compare policies side by side.

The Right Mix Depends on Your Income and Your Health
Medicare is a strong foundation that protects every Australian from catastrophic medical costs. Private insurance is a tool for specific gaps — faster elective surgery, choice of doctor, dental and optical cover, and tax efficiency for high earners. The biggest mistake is ignoring the numbers. Run the calculation on your income and age. If the MLS costs more than a basic policy, the decision makes itself. If you’re under 30 and healthy, Medicare alone is a perfectly rational choice until the LHC deadline approaches.
