Yeah Daniels even refers to Bunbury being the likely venue, probably more to play out there still so can't be confirmed yet.
Being able to schedule when you arrive and leave is still a big benefit too, no airport wait or the other rigamarole.
You'd expect it to be alternated, but obviously there's still one team that will get more benefit.
If you were North you'd likely want West Coast at Optus given their larger supporter base.
I think it's a good deal for NM. In 2023 they played 2 games at Optus decided by less than a kick, 1 win and 1 loss but made $0. Next year they'll play 2 games in WA and make 2 million dollars.
