So how big a market is tasmania lmaoThey manage to run a league across all capitals with far less resources than NRL, and arguably would get less from broadcast rights & sponsorship if they didn't have that footprint.. maybe even sending it into unviable territory.
AFL doesn't copy the NRL with midsize regional centres because
a) AFL-land doesn't really have many Townsvilles or Newcastles or Wollongongs to expand to, besides Tasmania (likely next).
b) They wanna put East Coast top tier teams in big metros (and have local derbies!).
c) They realise they're close to the limit for competition size right now - arguably they may have overstretched to 18 teams. However 20 teams will probably be it for some time - adding Tasmania (the closest they have to a small regional team to expand in AfL-land - and long teased) & likely either Perth 3 or NT or Canberra... Perth being "big metro", Canberra admittedly being a mid size market, but strategic as the national capital, and it's location near the Barassi line is strategic too.
instead of trying to turn the nrl into a watered down version of the afl why not just be happy with what the game has
you know last year our competition beat theirs by 23 million viewers and that’s ignoring rep games and nz
afl has no international presence. League has markets in nz and png which needs teams which will benefit the game hugely
