How much will it cost to study in Australia?

So, I'm curious about the financial aspect of studying in Australia. Can you give me a rough estimate of how much it would cost to pursue a degree there? Are there any scholarships or financial aid options available for international students? Additionally, are there any hidden costs that I should be aware of, like living expenses or insurance? Overall, what kind of budget should I be looking at to cover my education and living costs in Australia?
