Nice one fella, I definately have seen this car before Knew it was australian as well (coulda been because of those wheels which look like the commodore, umm i mean the monaro)
Intrestingly enough my dad used to own the only 1 in the UK except i think it was the sportier 1 the R400 GT had that reg aswell lol but he sold it to a friend who hasnt finished it yet but should be good fun when it is.
What it used to look like
When my dad bought it
Just needs painting now and its back on the road
