Good luck bigbizinpurse I hope things work out for you but unfortuntately I dont think the AFP will be that interested as the sum of money involved will be too small for them to worry about.
I have recent experience in trying to get action for a theft of a cheque book (I know it is not an eBay related theft) and I gave the police the full details of who took the cheque book (I found this out as the stupid people wrote a cheque paying for College fees) and they did very little. They interviewed the person concerned who denied all knowledge and as far as the police were concerned that was that they could do no more! But this same person then passed two more cheques but the police didn't want to know me. As a result I have no respect for the police forces in Australia they are far too busy doing other things to worry about petty crime.
I totally agree... I've experienced similar thing where I have absolute proof of who stole my mobile phone... reported & handed it over to the police here but they did NOTHING. Sorry to say this but they are so useless, can't rely on them at all
