Honestly kind of riles me up that they added WU and Macarthur when they could have just waited to add historic Sydney/Melbourne clubs this way. But muh growing population corridors :/
Yes WU both MAC were mistakes driven by derby madness. Though WU might yet get proper crowds & a soul when it's new stadium opens. They have basically been a nomadic road show til now.
But with all the franchise owners paying millions to enter the ALM, you can't just dump pro/rel on them. And with them effectively running the league (APL) they won't allow it anyway. This mooted A1/A2 split concept, seems a pretty fair and well thought through attempt at bringing in pro/rel. Seems to have worked for the J Leagues. But there is no rush to bring same concept into Australian football. The NST clubs will need to be patient.
