To redvx3's point, the Joondalup ground has a train line running near by, I'm sure they'd just put in another station stop there. There is also room to redevelop.
The original plan was for a train station but the government reneged.
Though W.A. is a football mad state, it's not a view shared by government.
West Perth could just become their reserves side, similar to peel for Freo. West Perth would welcome money being poured into their facility and surrounds I'm sure.
You don't know West Perth members. West Perth members rejected good money for simply renaming their club Joondalup.
West Perth would never commit to being anyone's reserve side.
The three Southern sides are committed to Fremantle.
The three Northern sides are committed to West Coast.
That leaves three clubs EAST.of Perth.
Even a South West club has more potential than a single arrogant WAFL club.
