Thoraiya Dyer is Australian (and an acquaintance), though she might not have been writing from Australian culture. She has a trilogy coming out with Tor sometime that might be of interest to you.

Disappointing to hear the Antipodean voices were largely missing, though. The New Zealand Maoris have some amazing stories about their encounters with settlers.

I will add you, if you don't mind. Please don't feel pressured to do likewise. I just like seeing what everyone else is reading.
