I noticed that the Australian Market is really quite hard to get a sniff in. In retail stores everything is expensive, around $100 a video game but on eBay its way below.
If you don't know what you are selling then you have no hope of finding a wholesaler, you will end google-ing yourself stupid.
Best thing to do is to get yourself on the phone for a couple of hours and see if any oppurtunities arise. If you need any extra help then let me know as I can pass your details on to one of our wholesale agents in Australia, they are top blokes and will give you a lot of use advice!
