I'm all ready buy off on a one sided discussion by someone named "Aussie Bloke"! Aren't you?
If it wasn't for that weird Ham transmission picked up a few months ago, I'd write this guy off as a complete kook (who knows, maybe he is). After all, despite the total hopelessness of the situation according to him, he won't lay out what he thinks/knows is going to happen. On the other hand, his date does correspond to the date (and apparent subject material) of the now-famous "snowball/Burrow" transmission.
