Private health insurance in Australia is growing at its fastest pace in years, but the growth is not evenly spread. Hospital cover has climbed to 45.8% of the population by 31 March 2026, and the fresh members joining are disproportionately older, costlier to insure, and buying thinner cover than the base they are entering. It is the kind of shift regulators everywhere watch for in a community-rated market: participation rising for reasons that make the pool harder, not easier, to price.
The 65-69 cohort is buying in faster than the pool can absorb
The Australian Prudential Regulation Authority has released its Private Health Insurance Annual Coverage Survey for 2025, a full age, gender and state breakdown of who held hospital cover at 31 December 2025. Of the 12,688,193 people covered nationally — 6,125,412 men and 6,562,781 women — the age skew is unmistakable. 53.18% of Australians aged 65-69 hold hospital cover, well above the 45.22% national average, while only 31.74% of 20-24 year-olds do, less than half the older cohort’s rate. In raw numbers, 744,762 people aged 65-69 and 569,678 aged 75-79 held hospital cover at year-end, cohorts large enough to move the pool’s average risk on their own. For an insurer setting next year’s premiums, the gap between who is joining the book and who is ageing out of it is the whole story behind the trend.
A pool built on cross-subsidy, now filling unevenly
Australia’s private health system runs on community rating: insurers must charge every policyholder in a state the same premium for the same product, regardless of age or health status, with a national risk equalisation pool redistributing claims costs so insurers with older, sicker books are not penalised for carrying them. Risk equalisation works by pooling a share of high-cost claims across all insurers and reallocating them according to each insurer’s membership profile, so no single insurer is punished simply for attracting older or sicker members. Cover splits broadly into hospital treatment cover, which pays toward admitted care, and general treatment cover, commonly called “extras,” which reimburses dental, physiotherapy, optical and similar day-to-day services, sold across tiers of rising benefit and price — Basic, Bronze, Silver and Gold. Extras cover is now more widespread than hospital cover: 55.5% of the population held some form of general treatment cover at 31 March 2026, up from 55.2% at 30 September 2025, against 45.8% and 45.5% respectively holding hospital cover over the corresponding dates. The whole structure depends on the mix of who buys in, and what they buy, staying reasonably close to the population it represents. APRA’s latest figures suggest that assumption is under growing strain, not because participation is falling, but because of who is driving it up.
Thinner policies, heavier claims: exclusions and excesses both climb
Rising participation would be an unambiguously good sign for the pool if the policies being bought were comparable to the existing book. They are not. The share of hospital policies carrying a permanent condition exclusion — meaning the insurer will not pay benefits relating to a named pre-existing condition, such as a joint or cardiac issue, no matter how long the policy has been held — rose from 58.49% in June 2020 to 68.41% by June 2025, APRA’s annual membership and benefits statistics show. Policies carrying an excess or co-payment, where the member pays a fixed amount before or alongside the insurer at each hospital admission, climbed from 85.83% to 88.24% over the same period. Both are now closer to the norm than the exception, meaning a growing share of the “covered” population holds products designed to shift cost back onto the member at the point of claim — precisely the members APRA’s age data shows are older and statistically more likely to need hospital care in the first place.
The benefit bill is following the demographics
Average hospital benefits paid per insured person rose from A$1,490.91 in the year to September 2024 to A$1,539.94 in the year to September 2025, the regulator’s September quarter summary shows, then further to A$1,587.08 in the year to March 2026, up from A$1,514.81 a year earlier — a rise of roughly 4.8%. Out-of-pocket costs are moving in the same direction: the average gap payment per hospital episode reached A$511 in the March 2026 quarter, APRA’s most recent quarterly release confirms. Neither figure looks dramatic in isolation. Together with an ageing membership base and thinner average cover, they describe a claims trajectory that is compounding rather than levelling off, one that risk equalisation transfers and premium filings will keep having to absorb as the membership base continues to skew older.
What the numbers mean beyond Canberra
APRA’s coverage survey lands weeks after the regulator finalised longevity capital rules for annuity writers, a reminder that Australian prudential settings across life and health lines are being recalibrated in parallel. The dynamic is not confined to Australia, either: private health insurance spend in Hong Kong has climbed well above pre-pandemic levels as regional demand for private cover accelerates, and carriers have been paying up for scale in Asia-Pacific life and health, including Allianz’s multi-billion-dollar deal for HSBC Life Singapore. None of this requires a crisis narrative — APRA’s own numbers show a system still functioning broadly as designed. But designed systems have tolerances, and Australia’s prudential regulator is now the one publishing the data that will decide how much further this pool can drift before pricing and product design have to catch up. For product and pricing teams outside Australia, the lesson is procedural as much as substantive: a regulator that publishes granular, age-banded coverage data every quarter makes this kind of drift visible years before it shows up in a loss ratio.
