Look around and Buy in Australia.. Better for the Economy Good on you Mark.

After you have paid your USD$1800 to a USA on line Store as Mark wrote is around AUD$2500.
Then there is postage UPS 4-6 days USD$70.80 and Duties and Tax USD $276.21 if bought from B&H in New York brings your total to USD$2146
Thats AUD$2966.43 And no mention about Insurance in Transit either. So not Cheaper after all.
