Who are the largest private health insurers in Australia?

Health insurance in Australia is dominated by two big players, who between them hold more than 52% of the market share of private health policies, according to the Australian Prudential Regulation Authority (APRA). The top ten health funds by market share in Australia are: 

  • Medibank Private and ahm:  27.4% market share 
  • Bupa: 24.7%  
  • HCF (including RT Health): 12.4% 
  • NIB Health: 9.4% 
  • HBF Health: 7.3% 
  • Teachers Health Fund: 2.6% 
  • Australian Unity: 2.4% 
  • GMHBA (including 2.3% 
  • Defence Health 2.0% 
  • CBHS: 1.5% 

These top 10 private health insurers between them hold 92% of all health insurance policies in Australia, according to the latest list of health insurers in a health insurance report by the Private Health Insurance Ombudsman (Quarterly Update: 1 July to 30 September 2022). 

However, the size of the company you’re considering shouldn’t be a deciding factor when getting a quote or choosing private health insurance. The health coverage offered and the affordability of the health insurance policy are major factors that help most Australians decide which policy is right for them, rather than in what position one insurer may appear on a list of private health insurers. Let’s take a closer look at the top ten insurers:

Medibank Private and ahm

Medibank Private, better known simply as Medibank, started life as the Australian Government’s not-for-profit health insurer in 1976. It was privatised in 2014 and is now listed on the Australian Stock Exchange. In 2009, Medibank acquired Wollongong-based insurer ahm (Australian Health Management), which added more than 700,000 to Medibank’s existing 3.7 million customer base.

  • Medibank offers a broad range of health insurance policies including at least nine hospital cover policies, four extras cover policies and packaged products, while ahm offers nine hospital cover policies and seven extras policies
  • Offers a 24/7 health advice line, a mobile health app, an online health hub and a health and wellbeing program called Medibank Live Better, which offers rewards through the Live Better app
