More than 15.2 million Australians now hold some form of private health insurance, yet nearly half the population still goes without hospital cover. That gap matters because the system is built around choice — and without a policy, your options in a hospital ward shrink fast. Here’s what you actually need to know.

Private health insurance in Australia sits at an odd crossroads. More people hold it than ever before in raw numbers, yet the share of the population with hospital cover has barely budged for a decade. Meanwhile, costs keep climbing. The average combined single policy now runs about $3,264 a year, and a family policy sits closer to $4,908. With premiums projected to rise between 3.9% and 4.4% in 2026, that adds another $127 to $216 annually depending on your cover type. For many households, the question isn’t whether they want insurance — it’s whether they can afford to keep it.
What I find most telling is why people actually take out a policy. The number one reason isn’t peace of mind or faster surgery. It’s to avoid the Medicare Levy Surcharge — a tax penalty for higher earners who don’t hold appropriate hospital cover. That’s a financial calculation, not a health one. And it shapes how the whole market behaves. If you’re trying to make sense of your options, start with the basics of how health insurance works in Australia before diving into policy comparisons.
The central concept here is private health insurance — a policy you buy from a registered insurer that covers some or all of the costs of hospital treatment, dental, optical, and other health services. Unlike Medicare, which covers everyone, private insurance gives you choice: which doctor treats you, which hospital you stay in, and how long you wait.
What I’d flag early is that most people don’t realise how much their policy is shaped by government rules rather than their own needs. The Lifetime Health Cover loading, the Medicare Levy Surcharge thresholds, and the recent Health Legislation Amendment (Improving Choice and Transparency for Private Health Consumers) Bill 2026 all change what a policy actually delivers. Understanding those levers matters more than comparing monthly premiums.
What changes when you don’t have hospital cover
The most immediate consequence of not holding hospital cover is financial, not medical — but it hits hard either way. If you’re single and earn over $93,000 a year, or part of a family earning over $186,000, you pay the Medicare Levy Surcharge. That’s an extra 1% to 1.5% of your taxable income on top of the standard Medicare levy. For someone earning $120,000, that’s $1,200 a year in penalty — often more than the cost of a basic hospital policy.
But the penalty isn’t the only risk. Without hospital cover, you’re treated as a public patient in a public hospital. That means you can’t choose your doctor, you can’t choose your admission date, and you’re placed on the same waiting list as everyone else. In 2024–25, over 800,000 Australians — 8.6% of the population — delayed or skipped specialist care entirely because of cost. That’s not just an inconvenience. For conditions that worsen over time, a delay can turn a manageable problem into a serious one.
There’s also a demographic split worth noting. Western Australians are the most likely to hold private health insurance, while people in the Northern Territory are the least likely. That suggests local factors — hospital availability, regional health workforce, and cost of living — play a bigger role than national advertising campaigns suggest. If you live in an area with long public wait times, the value of private cover goes up. If you’re in a city with good public hospitals and short waits, the calculation flips.
What I’d watch closely is the trend line. The number of Australians without hospital cover has been rising consistently since around 2000. That’s not a blip. It’s a structural shift driven by premiums that Nathan Kettlewell from UTS notes have been rising faster than wages and other costs. If that continues, more people will face the choice between paying the surcharge or buying cover they barely use.
Where people get private health insurance wrong
Buying hospital cover only to avoid the surcharge
This is the most common trap. You take out the cheapest hospital policy that meets the government’s minimum requirements, pay the premium, and assume you’re covered. But basic hospital cover often comes with high excesses, restricted doctor choice, and exclusions for common procedures like hip replacements or cataract surgery. You avoid the surcharge, but if you actually need treatment, you may still face thousands in out-of-pocket costs. The fix is to check what’s actually covered — not just whether the policy exists. If you’re unsure about the terms, a service like JustAnswer Medicaid & Insurance can help clarify what a policy really includes before you commit.
Ignoring the Lifetime Health Cover loading
If you don’t take out hospital cover by July 1 after your 31st birthday, you pay a 2% loading on top of your premium for every year you delay. That loading stays for 10 years. Someone who waits until age 40 pays an extra 20% on their premium for a decade. Many people don’t realise this until they’re quoted a price that’s hundreds of dollars higher than the base rate. The loading applies to hospital cover only, not extras, and it’s designed to encourage younger, healthier people to join the pool. If you’re under 31 and healthy, buying a basic hospital policy now locks in a lower lifetime rate.
Overlooking the difference between hospital and extras
Extras cover is more popular than hospital cover — 55% of Australians hold an extras policy. But extras don’t cover anything Medicare already covers. They pay for dental, optical, physio, and similar services. The top reason people take out extras is to access dental cover, and the second is optical. That’s fine if you use those services. But many people buy a combined hospital and extras policy without checking whether they actually need both. If you rarely visit the dentist and don’t wear glasses, a standalone hospital policy may be cheaper and more useful. Around 2.7 million Australians hold extras-only cover, which means they pay for services Medicare doesn’t cover but have no hospital protection at all.
Assuming all policies are the same
Private health insurers offer dozens of products, and the differences matter. Some policies cover private hospital rooms; others only cover shared wards. Some include pregnancy and birth; others exclude them entirely. The Health Legislation Amendment (Improving Choice and Transparency for Private Health Consumers) Bill 2026 aims to improve cost transparency by allowing the Department of Health to publish medical fees on the Medical Costs Finder website. That’s a step forward, but it doesn’t change the fact that comparing policies requires reading the fine print. The most expensive policy isn’t always the best, and the cheapest often leaves you exposed.
| Cover Type | Population Share | Most Common Reason |
|---|---|---|
| Hospital cover | 45% | Avoid Medicare Levy Surcharge |
| Extras cover | 55% | Access dental treatment |
| Combined Hospital + Extras | ~12.5M people | Comprehensive protection |
| Extras only | ~2.7M people | Dental and optical needs |
How to choose the right private health insurance for your situation
Start with your tax bracket, not your health
The single biggest factor in whether you should buy hospital cover is your income. If you earn above the Medicare Levy Surcharge threshold — $93,000 for singles, $186,000 for families — the penalty for not holding cover is often higher than the cheapest compliant policy. Calculate your surcharge first. If it’s more than the premium, buy the cheapest hospital policy that meets the government’s requirements. If it’s less, you have room to decide based on health needs rather than tax. The key is to check the current thresholds each year, as they’re indexed but don’t always keep pace with wage growth.
Match your extras to your actual usage
Dental and optical are the two biggest categories for extras claims. If you visit the dentist twice a year and wear glasses, an extras policy that covers those two areas may pay for itself. But if you rarely use any health services beyond what Medicare covers, an extras policy is essentially a prepayment plan with an insurer taking a cut. Look at your last 12 months of health spending. Add up what you paid out of pocket for dental, optical, physio, and similar services. Compare that to the annual premium for an extras policy. If the premium is higher, you’re better off paying as you go.
Understand the new transparency rules
The Health Legislation Amendment (Improving Choice and Transparency for Private Health Consumers) Bill 2026, introduced in February 2026, changes how medical fees are published. The Department of Health can now publish fees and likely out-of-pocket costs on the Medical Costs Finder website. That means before you choose a specialist, you can check what they typically charge and what your insurer will pay. This is a genuine improvement, but it only works if you use it. Before booking any private hospital treatment, check the website for the specialist’s typical gap. If the gap is large, you can choose a different specialist who charges within your insurer’s agreement.
Plan for the 2026 premium increase
Premiums are projected to rise 3.9% to 4.4% in 2026. For a single policy averaging $3,264 a year, that’s an extra $127 to $144. For a family policy averaging $4,908, it’s $191 to $216. That’s not catastrophic, but it compounds. If you’re on a tight budget, now is the time to review your policy. Look for policies with higher excesses — you pay more when you claim, but your monthly premium drops. Also check whether you’re paying for services you don’t use. Many policies include pregnancy cover, mental health cover, or rehabilitation services that add cost. If you don’t need them, switch to a policy that excludes them.
What’s coming next in private health insurance
The 2026 Bill also abolishes ‘product phoenixing’ — the practice where insurers close a product and reopen it under a new name to avoid premium restrictions. From April 2026, insurers must seek Ministerial approval for premium changes on both new and existing products. That should make it harder for insurers to quietly raise prices by rebranding. It’s a small win for consumers, but it doesn’t address the underlying cost pressures. Hospital and medical costs continue to rise faster than general inflation, and until that changes, premiums will keep climbing. The long-term trend is toward higher out-of-pocket costs and more people opting out of cover entirely.

Private health insurance is a financial decision first
The data is clear: most Australians buy private health insurance to avoid a tax penalty, not to get better care. That doesn’t make it the wrong choice — but it means you should treat the decision like any other financial product. Compare the premium against the surcharge you’d pay without it. Check what’s actually covered, not just what’s advertised. And keep an eye on the 2026 premium increases and the new transparency rules that might finally help you see what you’re paying for. The system isn’t designed to be simple, but the numbers are there if you look.
