Hi Tracy,
Number one, liquidated products.
Being in Australia, and the Aussie dollar being down against the US at the moment, importing anything is difficult.
I have a few Australian members that want to purchase, but the dollar combined with shipping, just making it too hard, so I would not be looking at liquidated products unless you teamed up with some other members to share the cost.
Number 2two, alternative selling platform.
Oztion and the Trading Post provide the biggest platforms outside of ebay in this country. Trading Post would be my choice, however ebay does tent to dominate the Aussie on-line marketing landscape.
You should also checkout Paymate Stores, only new, but seems to be quite cost effective, and I would expect the platform to grow in popularity quite quickly as it will be well marketed through Paymate's own payment gateway affiliations and so on.
Bonanzle.com, although US based is getting Aussie sellers setting up, along with some Aussie buyers starting to come by, and is free to list so you have nothing to loose by being there.
They would be your best options in my opinion.
