Brokers managing corporate health portfolios face a tightening renewal environment as hospital cost inflation continues to outstrip premium growth across Australia’s private health insurance sector. HCF’s full-year results for 2025-26 illustrate the pressure: the country’s largest not-for-profit health fund reported net profit of $87.8 million, down 55% from $195.3 million the prior year, as claims expenses climbed 11.5% against an 8% rise in insurance revenue.
The result lands as the Australian Prudential Regulation Authority (APRA) data shows the broader sector grappling with the same arithmetic. Industry-wide, the blended premium increase approved by the federal government for 2026 sat at 4.41% – yet hospital and treatment costs continue to outpace those increases, according to analysis from S&P Global Ratings on the structural cost gap facing Australian health insurers.
HCF’s claims ratio rose to 89.4%, up from 87.4% in 2025, reflecting a 10.5% increase in incurred claims expenses to $4.04 billion. The fund paid $3.95 billion in hospital, extras, and medical benefits during the year, while its membership base grew 3.9% to cover 2.15 million Australians.

The widening mismatch between premium income and claims outgo has structural roots. Medical technology costs, pharmaceutical pricing, and growing demand for specialist and mental health services are all accelerating faster than the government-approved rate increases designed to keep premiums affordable.
Grace Ng, partner in actuarial services at KPMG Australia, said the firm’s sector-wide analysis points to consumers making deliberate trade-offs between affordability and coverage.
“Our analysis highlights several trends shaping the sector, including rising claims costs, an ageing membership base and increasing uptake of lower-cost products. The data suggests consumers are making more deliberate trade-offs between affordability and coverage, creating important implications for long-term sustainability, member value and insurer performance,” Ng said.
That shift is visible in gold-tier enrolment figures, where downgrades have accelerated as mental health treatment costs drive higher premiums at the top coverage level.
For brokers advising employers, the picture carries direct commercial implications. Aon’s 2027 Global Medical Trend Rates Report projects Australian employer medical plan costs will rise 4.9% next year, following a 5.2% increase in 2026 – both well above the consumer price index, which has added cumulative pressure on corporate health budgets over successive renewal cycles.
Stuart Whitbread, director of health and benefits at Aon Australia in Sydney, said employers face increasingly difficult decisions around plan design.
“While the projected rate of increase has moderated slightly, employers still face difficult decisions around balancing costs with access to quality care. Organisations that take a long-term approach to workforce health will be better positioned to manage costs while supporting employee wellbeing and productivity,” Whitbread said.

An Ipsos survey of 2,500 Australians, prepared for the Members Health Fund Alliance, found healthcare cover tops the list of desired workplace benefits for 56% of respondents, suggesting demand for corporate health plans is growing even as their cost base deteriorates.
HCF chief executive Lorraine Thomas pointed to the fund’s 2030 Strategy as its framework for navigating the cost environment. The fund invested in wellbeing programs, expanded its dental and eyecare network, and maintained its market share at 13.81%.
Operating expenses fell $5.4 million to $532.4 million for the year, with the operating expense ratio improving to 11.8% from 12.9%. Despite the profit decline, total insurance revenue grew to $4.52 billion, and HCF maintained its position as the largest not-for-profit health insurer in the country.
The profit result underscores the narrow margins facing health insurers that prioritise benefits return over premium increases. The industry risk equalisation pool grew 9.8% in 2026, up from 7.5% in 2025, reflecting broader claims cost pressures across the sector.
For brokers, the takeaway sits in the numbers: when claims grow at 11.5% and premiums rise at less than half that pace, the gap has to close somewhere, and corporate health plan renewals are where that conversation increasingly lands.
