SBR,
TF kits are available but the price will leave you speachless. Most likely well over $700 AUD for a GS kit. Best bet is to start emailing the US hobby shops and see which ones will ship to Oz and how much freight will be. Freight could be as high as $160 USD so watch out for that. Tower won't ship kits to Oz so don't bother with them.
Keep an eye on ebay, especially the US site as TF kits come up all the time. I got the TF GS P47 and a TF P40 that way at really good prices.
Try Rick at MajorHobby in the US, he was pretty helpful last time I was making enquiries and he had some good deals on kits and on the frieght as well.
