I can be an alternate to Brette in this regard, if anyone buys something in the Melbourne area.

Concerning seamail, I have purchased five or six bulk lots form the US and had them sent surface mail. The quickest has been just over eight weeks. The slowest was just under 20 weeks (5 months). All arrived safely in perfect condition. I am very happy about these transactions and grateful to the Sellers for sending this way.

I think it should still be a valid option as it makes transations economically viable that with airmail would not be. However, it requires trust between the Seller and Buyer.
