Another option for you 4mangoes is to use a fulfillment company here in Australia if you are buying in bulk. Having an Australian address and an Australian item location is a serious advantage when dealing with local buyers.
Yes, it is an added expense, but depending on your market, it can pay off in the long run over drop shipping items in Internationally.
I am part of a partnership where we did some testing in regards to buyers responses to buying locally or internationally at a cheaper price. We sent up an International account, but listed and shipped from within Australia, as well as set up another International account for them exact same location and shipped into Australia.
We were selling into Australia the exact same products, but at a saving of 25%, including factoring in shipping prices. Our data over 6 months showed that our sales on the International account shipping locally were 75% stronger than or International account shipping into Australia.
EBay is a wholesale marketplace and cheap is usually king, however our own testing showed that there are other factors that really impact on the overall success of an account.
Always worth looking at all the options you have available : )
