Auckland has a team this year. So does Geelong. I guess adding teams means the league is doing well.
The national comp has had a few ups and downs over the years, including shutting down for a number of years. WA is problematic, some great teams come out of the west but the travel adds considerable cost to a semi professional league.
Geelong should be interesting, they will be a Korean team based in Geelong apparently. The Asian style of baseball is fun, we get to see a variety of Asian teams when they visit to play warm up games ahead of international tournaments. As for the Auckland team, I guess we will just have to lock up our sheep when they re in town...
