How about a competition as a whole? If membership with voting rights to a new structure as a whole were on offer then I'd happily part with $1000 p.a.
I think that if RA wants an Australian competition then they shouldn't try to run it themselves (we know how that ends)
For example (Only an example, the numbers are just examples before people start splitting hairs over percentages)
RA gives an unnamed billionaire the licence to run an Australian competition. Licence agreement includes financials and availability of players for test windows etc.
Clubs/groups of clubs/regions submit an EOI to be part of it, with criteria including financial viability etc
If example there are 8 teams who meet the criteria the teams each own part of the competition - let's say they each own 10% and the unnamed billionaire owns the remaining 20%.
Ownership structure of teams could be member-based, or privately owned or a mixture of both.
EDIT - And the state RUs are prohibited from having ANY involvement
