Unfortunately, due to the import regulations in Australia, importing any Gen3 HT and getting it registered on the road is pretty much impossible, unless (correct me if I'm mistaken) it's a personal import that you have owned overseas for 2+ yrs.
 
A Gen3 HT is indeed a nice idea, and it's a shame Toyota didn't release more over here in the later years.
So in reality - your options are;
Live with an ADM Targa (like a nice Bathurst edition!),  or get yourself a slightly older Gen1-2 HT here and apply TLC to make it as mint as you can afford.

Hmmm sounds interesting - Assume you only track the car now but sounds like it meets compliance? Are you at liberty to disclose more about how you got your car & its history?

I just bought it from a  guy here in Melbourne. It was fully compliance and registered. He had an engineers on it as well because of the modifications but isn't a repairable write off or anything. It's just a imported GTS Hardtop which has been modified. I didn't want to pay rego every year because I'm only using it as a track car so didn't bother registering it. He used it as his daily however and was fully registered. It's very low to the ground with a  big carbon front splitter so not able to drive everywhere on the streets also why I didn't register it. Has the compliance plates and all bolted to the firewall.
