I'm making the assumption that there are various fees for certain services, but is it safe to say that the vast, vast majority of government revenue from taxes comes from income taxes, business/corporate taxes and the GST? Looks like there isn't a property tax in Australia unless that property is specifically being used as an investment.
Yes, conventional taxation and the GST comprises the bulk of government revenue. There are also various things (such as 'stamp duty' when you purchase property) that function as
de facto taxes. So no official property tax on private homes, you're right, but we still pay 'stamp duty' when we buy a home. I know, it's mad...I'll refrain from ranting.

Taxation is kind of a basket case here, and despite the fact that Australia emerged from the GFC unscathed nothing has been done to address the fact that the mining boom is dead and gone, there's a
lot of uncertainty regarding China (which buys most of Australia's iron ore and beef, among other things) based on their recent actions in the South China Sea and their 'one belt, one road' policy (which Australia elected not to be a part of), not to mention the whole digital disruption/gig economy situation which is moving faster than any legislators can keep up with.
