Why is Binance Earn not available in Australia?

Could you please enlighten me as to why Binance Earn is not accessible in Australia? I've been hearing a lot about its features and potential returns, but it seems to be unavailable in my country. Is there a specific regulatory issue or legal constraint that prevents its operation here? Or is it simply a matter of Binance not having obtained the necessary licenses or registrations? I'm quite interested in exploring this platform, so any clarification on this matter would be greatly appreciated. Thank you for your time and assistance.
