I was successfully able to price match DCW at Teds using their online form. It takes them a day to process your payment, so you will be able to pick it up the following day. The price competes with those of Grey imports, but this is currently the best price you will be able to get in Australia. Grey Imports will save you at best $9 without local manufacturer warranty.

Note: You won't get the accessory mount mentioned in Teds Ad, since it's price matched.
Georges Cameras have that listed at the same price.
