WA's football boom will spark an exodus of fans eastwards this week as supporters of our two AFL teams urge their heroes on in cutthroat semifinals on Friday and Saturday.
And though the possibility of a derby grand final is a long way off, it is still a possibility.
Fremantle's history-making 16-point elimination final win against Geelong at the MCG on Saturday night - the club's first finals win away from Perth - has set up a Friday night showdown with Adelaide at AAMI Stadium.
West Coast followed the Dockers into the semifinals with a 24.18 (162) to 9.12 (66) thrashing of North Melbourne in front of 41,770 fans at Patersons Stadium yesterday.
It is only the second time that the two WA teams will travel in the same weekend to play finals.
In 2006, the Dockers lost to Sydney in a preliminary final in Sydney and the Eagles beat Adelaide in a preliminary in Adelaide.
West Coast went on to beat the Swans by a point in the grand final.
In a parallel between the two elimination finals, both Geelong and North Melbourne were held goalless in their opening quarters.
And both teams kicked their first goals at the 18-minute mark of the second quarter, although the champion Cats, who have won three flags in the past five years, rallied from there to make a fight of it while North capitulated.
