Check out Ebay for items that are being bid on (you'll be surprised at some of the unexpected things that ppl want!). Hitchy and Wattsy might be able to give you some pointers, although it's odd that they aren't in yet. Maybe they got banned

Be careful tho, you are obliged to pay GST (and maybe even duty) if the stuff you bring in is worth more than a certain amount. I rang customs once and the guy sed they collect on items if the tax component is >$50. Anything below that they couldn't be bothered with. A certain importer got caught not declaring the true value of frames he was importing and was slugged with a mega tax bill!!
