More than 15 million Australians now hold some form of private health insurance, yet the gap between what you pay in premiums and what you actually get back in claims is widening faster than most people realise. Out-of-pocket costs for hospital treatment have jumped 71% in five years, meaning the average person with hospital cover is now paying $685 in unknown gap payments per episode — on top of an annual premium that already exceeds $3,000 for a single policy.

The most common reason people take out private cover is to avoid the Medicare Levy Surcharge, according to industry surveys. The most common reason they don’t is cost. That tension — between the tax penalty on one side and the rising expense of cover on the other — is the real calculation every Australian household needs to make. And with 2026 premium increases projected between 3.9% and 4.4%, the numbers are moving in only one direction.
But there’s a layer beneath the premium figure that rarely gets the same attention. What you actually claim, how much you’re left paying out of your own pocket, and whether your policy matches the health events most likely to hit you at your current age — those are the details that separate a policy that works from one that just costs money. Here’s what you actually need to know.
One term you’ll see on every hospital policy document is Lifetime Health Cover (LHC) loading. It’s the penalty applied to anyone who takes out hospital cover after 1 July following their 31st birthday. The loading adds 2% to your premium for each year you were eligible but didn’t hold cover. So if you first sign up at 40, you pay 20% more, and that loading stays for 10 continuous years before dropping off.
What I tend to notice is that most people understand the loading exists but underestimate how much it actually costs them over a decade. On a $3,264 single policy, a 20% loading adds $653 per year — that’s $6,530 in extra premiums before the loading drops off. Worth weighing against the cost of taking out cover earlier than you think you need it.
Premium increases, gap payments, and the real cost of holding cover
The headline premium is only half the story. The other half is what you pay when you actually use the cover. APRA data from the March 2026 quarter shows the average acute hospital episode carries an out-of-pocket cost of $2,840. For medical services within hospital, the average gap is $68. For medical devices or human tissue products, it’s $732. These aren’t optional — they’re the costs your premium doesn’t touch.

| Cost Type | Current | 5 Years Ago | Change |
|---|---|---|---|
| Average known gap | $135 | $95 | +42% |
| Average unknown gap | $685 | $418 | +64% |
| Hospital acute OOP per episode | $2,840 | — | −1.0% (quarter) |
| Average single combined premium | $3,264 | — | +3.9–4.4% (2026) |
| Average family combined premium | $4,908 | — | +3.9–4.4% (2026) |
On the coverage side, the split between hospital and extras is revealing. Hospital cover sits at 45.8% of the population, while general treatment (extras) cover reaches 55.5%. The difference matters because many people hold hospital cover primarily to avoid the Medicare Levy Surcharge, then never use it. Meanwhile, they’re paying for extras they do use — dental, optical, physio — but often don’t claim the full annual limits they’re entitled to.
The age skew is even starker. People aged 60 and over account for less than 27% of the insured population but receive roughly 66.5% of all hospital benefits paid. That means younger policyholders are effectively subsidising older claims — which is how the system is designed, but also explains why younger members often feel they’re getting poor value. My first move would be to check your policy’s age-based benefit distribution and ask whether your current tier matches the kind of care you’re statistically most likely to need in the next five years.
Where policyholders get caught out
Holding the same policy from your 20s into your 40s
Private Healthcare Australia data shows that claims patterns shift dramatically across life stages. In your 20s, the most common claims are mental health treatment, knee reconstruction, and diagnostic procedures like endoscopy. By your 40s, colonoscopies, heart investigations, and bone and joint treatment dominate. By your 60s, hip and knee replacements and cardiac care are the main events. If you’ve held the same hospital policy since you were 25, there’s a good chance it doesn’t cover the procedures you’re most likely to need now. Reviewing your cover against your current health needs and life stage is the single most effective way to stop overpaying for coverage you don’t use while missing the coverage you do.
Choosing a policy on premium alone
The gap between the cheapest policy and the one that actually covers your likely procedures can be hundreds of dollars in out-of-pocket costs per episode. The average unknown gap — the gap you don’t know about until after treatment — is now $685, up from $418 five years ago. For cardiac devices, the average out-of-pocket cost hits $3,140 per episode. A policy that saves you $200 a year in premiums but leaves you exposed to a $3,140 gap on a single procedure is a bad trade. What I’d do is compare the gap schedule, not just the premium table, before switching.
Dropping hospital cover without understanding the LHC clock
If you take out hospital cover after 1 July following your 31st birthday, you pay a 2% loading for every year you were eligible but uninsured. That loading stays for 10 years. The data shows 1,187,740 Australians were paying this penalty at March 2026, and the number grew by 85,524 over the preceding 12 months. Dropping cover for even a short period can reset your continuous loading clock, meaning you start the 10-year count again when you rejoin. The loading doesn’t just cost you now — it costs you for a decade. If you’re considering dropping cover, check whether the short-term saving is worth the long-term penalty.
Not claiming the extras you’re already paying for
General treatment benefits paid out $1.86 billion in the March 2026 quarter alone. Dental was the largest component at $1.01 billion, followed by optical at $285 million, physiotherapy at $144 million, and chiropractic at $88 million. Most extras policies have annual limits that reset each year. If you’re not using your full dental check-up allowance, your optical frame benefit, or your physio cap, you’re effectively leaving money with the insurer. The fix is simple: check your policy’s annual limits, book the appointments you’re entitled to, and claim before the year rolls over.
Matching your cover to your life stage — and reviewing it properly
What to check at each age bracket
The table below shows the most common claims at each life stage, based on industry claims data. The second column is what you should look for in your policy’s product disclosure statement before you assume you’re covered.

| Life Stage | Most Common Claims | What to Verify in Your Policy |
|---|---|---|
| Early life (families) | Neonatal intensive care, tonsil removal, ear tubes (grommets), dental | Pregnancy and newborn cover, paediatric services, dental annual limits |
| Teens and young adults | Same-day mental health treatment, endoscopy, knee reconstruction, sports injuries | Mental health cover, diagnostic procedure tiers, sports injury coverage |
| Adults 25–44 | Childbirth, IVF, endoscopy, colonoscopy, mental health care | IVF and reproductive health cover, pregnancy waiting periods, mental health limits |
| Midlife 45–64 | Colonoscopy, heart investigations, bone and joint treatment, substance abuse care | Cancer screening cover, cardiac investigations, joint surgery orthopaedic tiers |
| Older Australians (65+) | Hip and knee replacement, eye surgery (cataract), cardiac treatment, rehab | Joint replacement cover, cataract surgery inclusion, cardiac device gap amounts |
How to review your policy without the jargon
Grab your product disclosure statement and look for three things: the waiting periods that still apply (especially if you’re considering switching), the annual limits on extras like dental and optical, and the gap cover arrangements for hospital procedures. Insurers that offer “no gap” or “known gap” arrangements for common procedures can save you hundreds compared to policies that leave you exposed to unknown gaps. The average known gap is $135; the average unknown gap is $685 — the difference is almost entirely down to whether your insurer has a gap arrangement with the hospital and doctors.
What to check before switching or dropping cover
- Have I held hospital cover continuously since 1 July after my 31st birthday? If yes, switching to a comparable policy won’t trigger new waiting periods (under portability rules).
- If I drop cover, will I face a new LHC loading when I rejoin? The loading reapplies based on your age at re-entry minus the years you held continuous cover.
- Does my current policy cover the procedures most common at my age? Compare the claims list in the table above against your policy’s exclusions.
- What are the annual limits on my extras cover? Dental, optical, physio, and chiro limits reset each year — use them or lose them.
- Am I paying for a higher hospital tier (e.g. Gold) than I need? Bronze and Silver policies cover fewer procedures but cost significantly less.
Upcoming rule changes and rate movements
Premiums for 2026 are projected to rise between 3.9% and 4.4%, adding $127–$144 to a single combined policy and $191–$216 to a family policy. Meanwhile, health insurance funds paid out 5% more for medical and hospital services in 2025 than the year before — a rate that outstripped the 4.41% average premium increase. That gap between claims growth and premium growth is one reason gap payments are climbing. The trend suggests pressure on premiums will continue, making it even more important to review your policy’s value rather than just its price. If you’re unsure about how pre-existing condition rules apply to your situation, that’s worth checking before any switch.

What the widening gap between premiums and claims means for your next decision
The numbers are clear: gap payments are rising three times faster than hospital costs, premiums are climbing faster than wages, and the age skew means younger policyholders are carrying a growing share of the system’s cost. The response isn’t to drop cover and risk the LHC loading — it’s to treat your policy as an active financial tool rather than a set-and-forget expense. Match your cover to your life stage, claim the extras you’re already paying for, and understand the gap arrangements before you need treatment, not after.
