Removing the higher private health insurance rebate for people aged 65 and over is good policy that is unlikely to place additional pressure on public hospitals, according to health economists. The proposed changes, set to take effect in April 2027, will mean the private health insurance rebate will depend only on how much money a person earns – matching the rules for people aged under 65. Currently, those 65 or over receive a larger rebate on their premium than someone under 65 on the same income, with the rebate rising again for those aged 70 and over.
To assess the impact of the change, health economists with the University of Melbourne analysed a decade of tax data for about 130,000 Australians. They examined how the incentive of the private health insurance rebate, and the penalty at tax time for high-income earners without insurance (the Medicare Levy Surcharge), impacts uptake. A co-author of the paper, Associate Prof Kevin Staub, said both have little impact on private health insurance participation.
Private health insurance uptake is driven by health needs and habit, he said, with many maintaining insurance because they have always had it. Giving those 65 and over a higher rebate means “the government is spending a lot of money to keep people in health insurance who wouldn’t actually drop it without the incentive”, he said. The research estimates 14,821 to 42,498 older Australians will drop their cover as a result of the policy, or 0.1% to 0.4% of the total insured population.
This is roughly in line with the government modelling which estimates 44,000 people will drop their cover following the change. Staub and his colleague, Prof Yuting Zhang, found by stopping the extra rebate for older Australians, the government would save about $730m to $940m a year by 2028-29. The health minister, Mark Butler, told ABC Radio Perth on Tuesday the savings would be directed towards aged care.
He rejected comments from the Australian Private Hospitals Association and the Australian Medical Association (AMA) that the changes would lead to a further strained public hospital system. The health economist and senior postdoctoral research fellow with the Australia Institute, Luke Slawomirski, described the University of Melbourne paper as “empirical analysis from highly skilled, independent researchers”. Slawomirski co-authored a submission from the Australia Institute to a Senate inquiry into the proposed changes, which is due to report its findings in October.
The submission said there is little evidence that subsidising private health insurance materially relieves pressure on public hospitals, since both draw on the same clinical workforce, not every private procedure would otherwise occur in a public hospital, and private insurance generally does not cover emergency-department attendance. Removing the extra age-based rebate is a fair and modest change, the Australia Institute found. The Commonwealth spends around $8bn a year directly subsidising private health insurance.
