The Oz health system is a mixed system which means that you can opt for public or private treatment. It's difficult to find GPs who "bulk bill" (you don't need to pay, Medicare covers it) but for hospital stays you can go into a public or private hospital. You will need private health insurance & you aren't fully covered for the costs so you've usually got some out of pocket expenses. My husband & I pay $150/month for hospital & "essential" (dental,physio,ambulance,etc) private health insurance.
