I mean, I'd personally prefer to see Canberra be the 20th team, then the Giants can go full time in Sydney by 2033. If they do go nuclear, I think a 3rd Sydney and 2nd Brisbane side would be good 21st and 22nd additions to the competition by the 2050s.If the Mighty Giants can go full time up here and get going with the locals, why not a 3rd team, and this time a club that has been around forever. The North Shore Footy club. One of the oldest clubs of any code in Sydney.
Also has more players and sides in divisions than any other club in Australia supposedly.
And before you say "They are the Bombers, no" they were originally known as The Bears.
