Thanks for all your comments and suggestions, really given me a lot to think about.
Sorry for being vague

I don't really want to say where I am in asia as the cycling world is very small here, and I'd rather not ruffle any feathers, but I wouldn't be comfortable spending the money I'm going to end up spending and having anyone where I live fit me for it. I'd rather spend a bit more and get a really good fitter to do it properly. For the rest of asia, well if someone can put me in touch with someone great to work with who I can communicate with that's good. But in reality I don't really care where I go, as regardless I'll get a holiday out of it too.
Also, my old injuries are quite substantial. Had a bad accident and one side of my body is significantly weaker and after many many surgeries has limited range of motion in key joints. In fact technically for cycling I am classified as disabled. So another part of the bike fit is that I'd like to make sure that I am getting the most out of what I have left, but also I'd like to make sure that I reduce the likelyhood of any more injuries down the road due to bad set-up.
I don't know that much about bikes and I certainly don't know what could be done with set-up / custom frame to make it more comfortable and more efficent for me. So I would be relying a lot more than many of you would be on the fitter and the builder to not just do what I ask but also suggest things.
I used to be a reasonably competitive sportsperson, and cycling is one of the only sports left open to me. I plan on doing some one day racing and stage races around the place. I'm not going to set the cycling world on fire, but I'd like to be as competitive as I can be for whatever training I put in.
As dsut4392 mentioned the strength of the Aussie dollar doesn't make Australia that attractive compared to elsewhere right now, but it's close and I have friends in Melborne. And thanks for the link PCutter, the Baums really are pretty! Very tempting
The US/UK ones look better in terms of exchange rates. As LugHugger pointed out the builders might not be the best fitters... so does anyone have any reommendations on fitters for Lynskey, seven or zinn?
Thanks for the Rikulau info funnytanlines, will definately check them out.
Thanks again for all the comments and suggestions. No idea how I'll end up making the decision on where to go, but I guess there is no huge rush (except I want it now!!

).
