Winksmith,
Its troubling to see all the posters who respond to your post without having a clue about your question.
I suggest you post that looking for an FAA CFI in Aus or NZ who can do an FAA Flight Review / IPC if you have an instrument rating.
I've got an FAA CFI that needs requires a ride to be revalidated, and in preparation for that, and a return to Aus, I've been studying the legislation in both countries.
From my read, there is NOTHING stopping an instructor from doing this by mobile web cam.
To make that a little braver, my take is that you could compose a check list for a local instructor to give on a BVF and forward a copy of the BVR Flight to the FAA CFI and have him "sign your log book".
If you complete an IPC overseas, you still lack what is called "the oral test" for the Australian IPC requirements, that in theory, could be done by skype or even telephone conference.
All that you need to do is contact someone with a FAA CFI who is willing to do that for you.
