Plenty of commonwealth origin immigrants up there as well.
That's true of course, i have some inside knowledge on a couple of the district cricket teams and probably 70/80% of the boys are both good cricketers and footballers, plenty are in development squads at both West Perth football and Joondalup district cricket teams.
Some have dropped out of footy this year ( year 9/10 ) to concentrate on cricket, none have dropped out of cricket for footy.
Football up here should probably find another public high school for for it's football program, Wanneroo High is seen as not a very good school, whilst the cricket Program at Belridge SH is these days seen as a good school to send your kid to.
