The bike test was at a demo day only a few weeks ago. It's also in the latest Trailrider magazine along with a one pager advert on the Terra. I'd say there would be quite a few TR650's in stock in Australia.
Aussie Trailzonemag have a Terra as a project bike. Mods & farkles are likely to be tested & reported.
They've been "working on" it for quite a while now. I'd have thought there would have been some sort of prototype hit the photoblogs by now. They're just a few hours ride from my house along some fine sealed and unsealed roads. I'm surprised that I haven't gone venturing up there myself to knock on their door and see what's up yet.
Here is a good comparision test between the TR650 Terra, The KLR650, the Tiger 800 Triple and the KTM 990 Baja and the Super Tenere 1200 http://www.cycleworld.com/2013/03/29/2013-adventure-bike-comparison-test-review-stats-photos/
