Well despite the best efforts of some on here who for their own reasons cannot accept the idea that a 3rd team will likely come from North of the River just watch it happen. God for bid dont mention Joondalup as a possible base which is not certain at this time.There are 9 WAFL teams.
South Fremantle, East fremantle and Peel identify heavily with the Dockers.
West Perth, Subiaco and Claremont are on the west coast and might lean to the Eagles.
East Perth, Perth and Swan Districts could technically be the feeders for WA3.
East of Perth you have the strongest Noongar representation - red yellow and black boomerangs.
Where do you think the future growth will happen in Perth. Why have State Govts of both persuasions poured money into the Northern Corridor very roughly starting at around Mindarie.
When the rail line and Freeway get to Yanchep that corridor will expand quicker - People expect services no matter where they live.
Think about the Wanneroo Council growing from a outer suburban set up to a full blown city with an expanding population. The long long time mayor pulled up stakes and moved into federal politics at the recent federal election. Very curious moves people make in their careers.
