I think this would be worth investigating. Each regional Provence has their own criteria. I just used one Provence.
HOW TO MIGRATE TO AUSTRALIA
If you have a successful business overseas, you can be nominated by a state or territory government to establish or manage a business or invest in Australia.
Remember, the ACT government does not grant visas. It is the Department of Immigration and Border Protection who is responsible for all visa processes.
The ACT is only involved in the nomination of a skilled or business visa applicant to live and work in Canberra.
