Sydney is probably the best place in Australia to buy a ski. You have access to pretty much every brand of ski.
Dealers of some brands include Australia wide delivery in their retail prices so if you pick up locally you can save a couple of hundred bucks. Not sure about Epic.
You are unlikely to get a discount on a V9 any time soon. Those things are like so hot right now.
