Need to know

  • More than half of Australians (54.6%) have extras cover for services like dental check-ups, optical, physiotherapy and chiropractic
  • Just under 45% of Australians have hospital cover for surgery, accidents, illnesses or chronic disease management in hospital
  • Medibank and Bupa hold over 52% of the private health insurance market between them

Private health insurance in Australia is a complex, ever-evolving beast. COVID-19 and the cost of living have affected industry trends significantly, with people balancing their health needs with their wallets.

Find out more about who has private health insurance, what the latest trends are, and the major private health insurance players in Australia.

How many Australians have private health insurance?

From 2015–2019, the rate of Australians with private health insurance steadily declined, but this trend has since reversed. 

People took up private health insurance during the COVID-19 pandemic as they became more focused on their health.

Somewhat surprisingly, Australians took up extras cover even though out-of-hospital health services such as dental, optical, chiropractic and physiotherapy were restricted due to social distancing. 

In 2023:

  • 54.6% of Australians have extras cover
  • 44.9% of Australians have hospital cover
  • most people have a combined health insurance policy.

It will be interesting to see how health insurance membership figures develop in the next few years.

Thinking about buying health insurance? Our experts explain what you need to know about hospital cover and extras cover as well as a few other things you should be aware of before you commit.

Hospital insurance policyholders by age group

When looking at total membership numbers for hospital insurance per age bracket, the highest amounts are in the groups aged 35 through 55 years – likely because there are more Australians in these age categories.

The proportion of the population with hospital insurance increases with age, though. People are most likely to have private hospital insurance when they're aged 75 to 79.

Young adults aged 25 to 29 are the least likely age group to have hospital insurance. This group has generally matured beyond relying on their parents' family policy for their health needs, but are not yet affected by the Lifetime Health Cover loading for hospital insurance, which kicks in at age 31. They're also less likely to incur the Medicare surcharge tax, which affects singles earning more than $93,000.

If you currently have health insurance and want to check whether you're getting the best deal, we developed a tool that lets you compare health insurance policies based on your needs so you can find cover that works for you, and potentially save yourself hundreds.

Which health insurers are Australia's biggest?

Private health insurance in Australia is dominated by Medibank and Bupa, who hold 52.2% of the market between them, with HCF, NIB and HBF rounding out the top five.

  • Medibank (including AHM) – 27.5%
  • Bupa – 24.7% 
  • HCF – 12.4%
  • NIB – 9.4%
  • HBF – 7.3% (most HBF members are based in Western Australia)
  • Teachers Health – 2.6%
  • Australian Unity – 2.4%
  • GMHBA – 2.3%
  • Defence Health – 1.6%
  • CBHS – 1.5%
  • Others – 8%

Health insurance premiums are increasing by an average of 2.9% in 2023, but depending on which insurer you're with, you might be able to lock in your current premium until 2025. Read more about how to avoid health insurance price hikes.

Market share of smaller health funds

There can be some distinct advantages to going with a smaller health fund. All health funds, big and small, are required to meet the same standards, and small funds will give you just as much choice over who treats you as larger funds – in a lot of instances, the smaller funds will even be cheaper.

These 22 health funds have less than 1% market share each.

  • ACA
  • AIA Health
  • CBHS Corporate
  • CUA Health
  • Doctors' Health
  • HCI
  • Health Partners
  • HIF
  • Hunter Health
  • Latrobe Health
  • Mildura Health Fund
  • Navy Health
  • Onemedifund
  • Peoplecare
  • Phoenix
  • Police Health
  • QCH
  • Reserve Bank
  • St.Lukes Health
  • Transport Health
  • TUH
  • Westfund

Health funds and their brands

What can make health insurance confusing is the sheer number of funds you can choose from – something that gets trickier when you realise a single health insurer can operate multiple brands. In some cases it's a matter of a premium brand and a budget brand, like in the case of Medibank (premium) which also operates AHM (budget). It's the same for GMHBA (premium) and Frank (budget).

Some health insurers will sell the same policy under different brand names, and sometimes with different premiums. For example, NIB sells policies under the following brand names:

  • AAMI
  • Apia
  • ING
  • Qantas
  • Priceline
  • Real
  • Seniors
  • Suncorp.

When our experts analyse and compare health insurance, they compile data on thousands of policies from more than 40 insurers, including the sub-brands that insurers like NIB own. Unlike other comparison sites, we don't take commissions from any insurers, which means we can show you more of the market and find the best-value policies that match your needs.
