Im not sure if any of your lovely people can help..

I have my next gig on the 9th Jan, I would love to do something a little different but not sure as yet (Its a heavy metal/goth club)..

I would ideally love to incorporate a large prop of some sort but I am not sure what as yet (still throwing ideas around).

Would anyone know of any places in Australia (Melbourne would be better) that sell second hand props or anything like that?
