Thats ok, i joined last week and it is a bit confusing.
Go to suppliers, click or search for you specific item, then when it shows the results there is an optiion on the right saying 'sort by country' and select 'australia'.
I've looked as oz sites (i'm in melb) and realised that the prices are a bit high, except maybe for Link hidden: Login to view so i'm taking the plunge and looking at stuff from china: dhgate.com, chinavasion.com.
I've ordered small amounts to be safe, and hopefully they will arrive in due time.
Cheers mate.
