Suggestions on how Australians can buy Bitcoin in Australia

As far as I can tell, almost all the on ramps to crypto exchanges have obstacles to Australians buying Bitcoin. The big Australian banks are making it very difficult to send any significant amount of fiat to a crypto exchange. The equities and crypto exchanges like Interactive Brokers where one probably would be able to send fiat currency won't sell to Australians. Etorro won't let Australian investors self custody. Commonwealth bank is not only holding fiat but says it may only allow 10k a month to go to a crypto exchange. Australians are running out of options to buy BTC which of course is the whole aim of traditional finance. An effective Chokepoint like is taking place in the US.

Anyway the above problems is not an exhaustive list. Any suggestions on how to freely send fiat to crypto exchanges?

Thanks
