You will probably see a few terms that you haven't come across before if you have never rented a car in Australia. Here are some important ones:
What it is: RHCA (Reciprocal Health Care Agreement with Australia) If you are a resident of a country with a Reciprocal Health Care Agreement with Australia, then you are covered for medically necessary care when you visit Australia.
What it does: Under the RHCA scheme, you may be entitled to limited Medicare benefits. Benefits are only for basic medical services or only for emergency treatment and only under certain conditions. Many items such as ambulance, dental work, subsidised medicines, and private patient hospital costs or other ancillary/extras cover or services are not covered.
RHCA Member Countries
What it is: If you're from the USA, you may be familiar with the term "deductible", meaning the amount of money you pay before your insurance company begins to cover your costs when you need to make a claim. In Australia, a deductible is known as an excess.
What it does: Let's imagine your rental car agreement provides insurance with a $1000 excess. The car gets dented during your trip, and it will cost $2500 to repair. As long as the terms and conditions on your rental agreement have been met (more on this later), you will only need to pay $1000 towards the repair bill, and the rental company will pay the remaining $1500.
