Not sure about Rays, but you can get Enkei GTC01 via Wheel Demon (
Wheeldemon - Home). I beleive they are located in Dandenong/Hallam area.
For brake kit, talk to Howard Reynolds at Race Brakes in Yarraville, he is one of the best brake specialists I have come across and does excellent work at reasonable rates. He can put togerther a Brembo or Alcon brake kit to suit your needs/budget.
BTW, if you proceed, let me know as I am interested in taking the Akebono OEM front/rear calipers off your hands at a reasonable price if you proceed. PM me if you'd like to discuss.
