Do I need a passport to travel domestically in Australia?
Not necessarily! Domestic travel is pretty simple. But if you’re taking domestic flights you will need some sort of form of photo ID, whether it’s a passport, driving license, or social security card.
Do I need travel insurance to travel domestically in Australia?
You can get travel insurance for domestic travel in Australia, though it usually won’t cover medical expenses. But as an Australian resident you can always use medicare to cover that portion of the insurance, and get insurance for things like loss or theft on the road.
