Not sure about Perth 3 but can understand the case for it. I think Brisbane 2 would be a good shot by the 2050s, but maybe not if there's no new stadium.I’m all for a Canberra team as it gets the Giants full time in Sydney.
So Tassie, Canberra, Perth 3, North Shore?
I think you could potentially make a case for 24 teams in <30 years, those four you mentioned + Brisbane 2 and either NZ if work is put into it and demand grows or a 3rd Adelaide team to even up the number of teams.
I'm all for expansion and there are some clever ways you could break up the competition without pro/relegation or conferences (instead, have as many teams play each other once as possible but guarantee double ups for interstate teams).
But this is all hypothetical and the demand has to be there and growth and the club presidents have to vote for it.
