Another vote for the Never summer proto. Sounds like it ticks all your boxes.
It will be expensive in Oz but they are built to last. I really enjoy riding my proto and its so versatile. It slays powder and carves well, great in trees and soft enough for some park action (although this is not my thing). Also clings to the ice with the vario grip. Not the dampest board but I prefer boards with good feel.
If you can get hold of one I recommend it. The SL is a little more damp but very similar and maybe easier to find.
