How to choose the best health insurance for your requirements


Firstly 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. Hospital cover has been categorized into four tiers – Basic, Bronze, Silver and Gold. These tiers, each with a minimum level of cover guaranteed, will make it easier for you to compare and choose the right policy that meets your requirements.

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, upfront, 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 does not cover. 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 specific benefits.


A cheap policy isn’t necessarily the right policy for you. Make sure to compare funds that provide the coverage you require before reviewing cost. This way, you’ll generally be able to find an acceptable value policy for an affordable price.

Waiting Periods

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.

Which type of health cover to consider?

Select Private health insurance cover helps you avoid the Lifetime Health Cover (loading) and Medicare Levy Surcharge (MLS). It’s also essential to consider having adequate health cover 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 most appropriate health fund to suit your requirements, you need to be clear about the type of plan you need:

hospital 2 icon

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 icon

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

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.

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.
  • Who are the top 5 health insurance companies?

    There is no ‘one best private health fund’ that will satisfy everyone’s requirements all the time.

However, the top 5 private health insurance companies in Australia by market share are:
    • Medibank

  • Which health insurance company offers the best cover for overseas visitors?

It is generally worth getting OVHC quotes from a variety of providers to determine which one best meets your particular requirements.
  • Which company offers the best cheap health insurance?

    To meet your requirements, it is advisable to compare the various policies on offer. In Australia, the most affordable health insurance plans are generally the Basic Extras only cover options, which usually only pays for essential general treatments received outside of the hospital.
