parts support in Aus

[falcon pwner]

I'm relocating internationally to Sydney in the next couple of weeks and am hoping to get involved with the local 1:10 off road racing scene. I'm wondering what makes and models have good parts support in Aus? I'm particalarly interested in 2wd buggy and 2wd short course. Or is 4wd SC more popular? I'm partial to metric if possible, but will buy a new set of allen drivers if necessary. Thanks fro your help, you guys' tracks look fab!
