The the people of Australia ALWAYS pay in the end either directly or indirectly...
Don't you mean: "people ALWAYS pay in the end"?
It's the same everywhere, mate. (Just that we pay less than just about everyone else, our government does an amazing job providing the level of services it does on such a low ratio of tax to GDP.)
The government has no other source of funds - has it?
Uhm, no, it doesn't.
