RE: Help with parts needed! :)
That pipe is one of the better pipes for that size motor in the RS4. Here is a cheaper one on ebay that I'm sure you could contact the guy and see if he could ship it to Australia for a bit more.

You can save quite a bit by getting them off ebay from reputable sellers. Good luck.
