If you are a permanent resident visa holder and have a current driver's licence from another country, in English or with an Intarnational translation of drivers liocense, you are allowed to drive for your first three months after arrival.
After the three months, if you want to drive, you will need to have the appropriate driver's licence. This will usually require you to pass a knowledge test, a practical driving test, and an eyesight test. In Australia, drivers' licences are issued by state and territory governments.
If you're going to be in the Australia for more than six months, you can get an international translation of driver's license before you leave home, or you can apply for a license in Australia when you're there.
If you're going to rent a car, you will need your local, unexpired driver's license (that you've held for at least one year) and a credit card -- not a debit card.
