Hi Ben.
I bought a Ti bike about two months ago, second hand from Sydney. It's a Planet x made by van Nicholas. All the company's I contacted in Australia were either way too expensive or slow to provide the finished product. I wanted something pretty quick, not in 6 months. That's why I went second hand, be it that it was only 6 months old. Good luck finding a bike, hope you find what you are after.
Cheers.
