Please no. This is literally the worst track in Australia. There are a lot of racing circuits in Australia, most of which I wouldn't want to see in GT ahead of the huge number of great and important circuits from around the world. I wouldn't even want either of the two main circuits from Tassie in the game, despite them being in my home state, because I don't think they're good enough. And those are both way better than Qld raceway. It's dull dull dull dull dull. I used to hate driving it in Race Driver 3. It's not just the simple layout, there are some half decent tracks in Aus with simple layouts (Baskerville Raceway for example), but it's also completely flat. No elevation changes at all.
Australia has so many good tracks that would be good in GT, like Calder Park, Surfer's Paradise, Hiden Valley, Mallala, Phillip Island, Sandown, Winton, Albert Park, Sydney Motorsports Park, Adelaide (Both the F1 and shorter V8SC courses). I'd want all of those before even thinking about Qld Raceway. Even then, I'd still want Symmons, and pretty much every other circuit before Qld. Just my opinion.
