Independent summaries of Australia's major health funds. Updated April 2026.
Medibank is Australia's largest private health insurer. Its size delivers a strong hospital network, which means members are less likely to face gaps when choosing a specialist. The Live Better rewards program is well regarded. As a for-profit ASX-listed company, premiums tend to reflect this. Customer service reviews are mixed. The 2022 data breach affecting nearly 10 million customers remains a significant reputational issue for the fund.
Bupa is the second largest health insurer in Australia and part of a global healthcare group. It operates its own dental centres and has one of the largest dental networks in the country, which is a genuine advantage for heavy extras users. Family cover options are comprehensive. Like Medibank, premiums are on the higher end and customer service experience varies. Bupa has faced regulatory scrutiny over claims handling practices in recent years.
HCF consistently receives higher customer satisfaction scores than the major for-profit funds. As a not-for-profit, all surplus returns to members through better benefits. The More for Teeth dental network offers no-gap preventive dental at over 500 locations. The benefits paid ratio of 89.2% over 10 years is above the industry average of 85.6%, meaning members get more back from their premiums. The main limitation is a smaller hospital network than Medibank or Bupa.
nib is popular with younger Australians and those who prefer managing their insurance digitally. The nib App receives strong reviews for ease of use. Cover options are clear and straightforward. As an ASX-listed for-profit, premiums have increased faster than the industry average in recent years -- their 2025 increase of 5.79% was well above the 3.73% industry average. Strong overseas visitors health cover makes it a go-to for international workers and students in Australia.
ahm is independently run but owned by Medibank, giving members access to the Medibank hospital network at generally lower price points. Positioned as a no-frills competitive option, policies are simple and easy to understand. Customer reviews are average -- functional but without the extras programs and perks of the major brands. For price-conscious consumers wanting Medibank network access at a lower cost, ahm is worth comparing directly.
