Mike,
I purchased from BH Photo in the US. I think all up it came to $960 AUS including shipping/handling/credit card charges (it took 3 days to arrive from placing order) and was exempt from sales tax + duty. This was the US version so (according to BH website) the warantee can be honoured locally.
As a comparision, local camera stores are selling it for $1200-1450 AUS. On ebay second hand ones seemed to go for $750-1000 (overpriced if you ask me!).
When you think of it as a 70mm f2.8 refractor astrograph it seems not a bad bargain
