This is the only site I could come across that had a kit for the MKII, but then again I found it by accident. They only have 1 choice. http://www.rollhard.com/kaminarimr2supra.htm
What part of Australia are you from? I know a place in Brisbane that can supply body kits for a Mk2. I was over there a couple of weeks ago and they tried to sell one to me, but since 99% of bodykits are totally gay I told them I wasn't interested. IMO the Mk2 looks great just how it is.
