2020 Biggest health funds in Australia

Our top 10 list of private health insurance companies is based on market share. Market share shows the competitive position of an insurer by assessing how many Australians enrolled in a particular health fund. When an insurance provider owns more of the market, it usually means they have sold a lot of policies, which might indicate that more people are drawn to their offering, and trust them with their health protection needs.

According to the Australian Prudential Regulation Authority (APRA), the 5 largest health funds in Australia account for over 5 million health insurance policies.

The higher the amount of policies sold, the more likely it generally is that the health insurer is receiving higher profits, which could lead to lower premiums and more benefits for its members. This is especially true if the health insurer is a not-for-profit organisation, because they don’t have any shareholders to whom they pay dividends. Instead, the profits go straight back into the fund to be used for its members.

How to choose the best private health insurance

Private health insurance not only helps you avoid the Lifetime Health Cover (loading) and Medicare Levy Loading (MLS), but it’s also an essential purchase if you have a health condition, are thinking about becoming pregnant, have a family, or are getting to an age where more medical assistance is required.

There are many private health funds in Australia competing for your business. However, to find the best health insurance provider to suit your requirements, you need to be clear about the type of plan you need:

Hospital cover

Covers some or all of the costs for treatments received in the hospital. The protection you’ll receive depends on the level of hospital insurance your purchase: Gold, silver, bronze or basic.

Extras cover

Provides a benefit for treatments and services received outside of a hospital, for example, optical, dental and psychology. Depending on your fund, you generally have a choice between comprehensive, mid or basic extras.

Combined cover

Includes both hospital and extras. Many insurers will allow you to tailor cover to suit your requirements.

Take note: You do not have to buy hospital and extras from the same company. Find what works for you, even if that means buying a hospital policy from one insurer and an extras policy from another fund.

policy from one insurer and an extras policy from another fund.

A checklist to help you find the best health insurance for your requirements


To determine who offers the best health insurance, you should first decide on the type of coverage you require, for example, a basic hospital policy will most often cover accommodation as a private patient in a public or private hospital but exclude high-cost services like pregnancy.


Your chosen health insurance company might use dollar or percentage amounts or both to show how much you can claim for a specific service, for example, $250 per person or 75% of the total costs.

Annual limits

A limit refers to the maximum benefit payable each year for a specific service/treatment. Annual limits differ between funds and policies, so make sure that you review the company’s Standard Information Statement (SIS).

Co-payments or daily excess

In exchange for lower premiums, hospital policies generally have co-payments, also known as an excess, wherein you agree, up front, what amount you’re willing to pay each day you’re in the hospital. Depending on the insurer you’ll typically have the choice of zero, $250 or $500 excess.

Health Insurance Reviews

Read what customers are saying about the company, how satisfied they are with their service and how many complaints the company annually receive.


Carefully review which services and conditions your provider will not pay benefits towards. With the new health insurance reforms where hospital policies must adhere to a simplified classification system; Gold, Silver, Bronze and Basic, your health fund might decide to exclude or include certain benefits.


A cheap policy isn’t necessarily a good policy. Make sure first to compare funds that provide the coverage you require and then review their cost. This way you can generally find a good value policy at an affordable price.

Waiting Periods

It’s vital that you look at the length of time you’ll have to wait before you can claim a benefit, for example when you have a pre-existing condition, you generally have to wait 12 months. Waiting periods can range anywhere from 1 day, two months to a year and are different between insurers.

Market share

If a health fund owns more of the market, it means that they have sold more policies, which could mean that more people are trusting that particular health fund.

Be sure to consider this checklist when comparing health funds so you can find the best health policy suited to you and your family’s requirements.

Frequently asked questions

  • Which health insurance company is the best in Australia?

    There is no best health insurer for every person. As the saying goes ‘you can’t please all people all of the time’. Each person and family unit is different, with specific health requirements and budget. The best private health insurance provider for you should be one that you can afford and provides the type and level of coverage you want.
  • How do health insurance companies work?

    In Australia, residents generally have access to free health care, called Medicare. However, to relieve some pressure off the public health system and shorten waiting times, you are encouraged to take out private health insurance, if you don’t, you’ll usually have to pay an LHC loading and MLS fee. In exchange for paying a premium, the private health insurance company pays a portion of your medical expenses.

    Medicare generally pays up to 75% of your medical treatments under the Medicare Benefits Schedule (MBS). Your private health insurance must then pay at least 25% of the MBS fee. You are then responsible for the remainder of the costs. However, the private health insurance company you choose can pay more than the required 25%.
  • Can health insurance companies exclude pre-existing conditions?

    No, health insurance companies cannot exclude pre-existing conditions, for example, asthma, cancer, or diabetes, because the Australian Federal Government prohibits it. Private health insurers may not refuse to let you buy health coverage or even to charge you a higher premium because you have a pre-existing condition. They can, however, have strict waiting periods associated with pre-existing conditions.
  • How much does health insurance cost in Australia?

    The premium you’ll have to pay for your health insurance policy depends on various factors, including the state you live in, the type of plan you want (hospital, extras or combined), the co-payments you’re willing to make and the level of coverage you require (comprehensive, medium or basic). Remember, premiums rise every year on the 1st of April.
