Movie World Aus Harry Potter store?

I'm trying to get a costume together for the release if DH2, and a friend suggested the Harry Potter store at Movie World on the Gold Coast. I live a few hours away and am not a very big fan of the park as a whole, so I was hoping to find out before I go what sort of merchandise they sell. I'm looking for a robe, sweater, tie, wand, etc., preferably ravenclaw. Does anyone know if they have all of this stuff now?? Thanks =)
