Answer
The great news is that the government has a website where Private Health Insurance is all listed together so that you can Compare health insurance policies .
To compare policies across each of the health insurers operating in Australia, all you need is the type of cover you want, who the policy will cover, and where you live. PrivateHealth.gov.au contains details of every health insurance policy available in Australia.
