A little birdy (ok, a Google search) has turned up the following interesting forthcoming releases from the Perth Mint: Also a few other interesting coin series - Australian Battles (1oz silver proofs) and Australian Sea Life II (1/2oz silver proofs).

We got a piccie of the 20oz coin? I can't claim to have ever seen one personally... Although I have a 20oz PM bar
