Only 1 team is playing at Optus(Freo next year) the other is playing at Busso.The slight difference there is that we didn’t sell games to play our opponents at their home stadium
From memory it was Port in Darwin and The Suns in Cairns so you could make an argument that the venue was at least neutral (harder to sell that on the suns game)
Selling a game to play one of the WA teams at Optus seems like putting money a bit too far ahead of actually giving the team the best chance to win the game
Also, North have a better track record at Optus recently than they do in Hobart.
Finally, teams that barely travel shouldn't really be complaining that the 2 teams who travel way more than anyone else get some schedule relief.
