Well if he didnt send it registered then I wouldnt think I could even approach Australia Post anyway as I have no proof of what happened.  I mean I guess I got my money from the original sale, but what a huge pain in the a** it has been!!  I guess its a learning experience.

So, in summary, I should now explain to him that the set is damaged, that I will not be refunding the money as I cannot resell it.  However, as he has paid for it, I am happy to return the damaged item to him at his postage cost if he wishes.  Is that right? Do I need to (or even should I) provide him eveidence or details of the damage? I have taken photos, but I'm not sure how far I should go with this.
