Myself and a few other Liberty members here in North QLD have also been discussing what to do with our quickly degrading dashes. Because of the high temperatures, and sun almost all year round, ours are probably worse than a lot of others down south.
The Part # for yours is 66040AG081 I believe (I'd confirm with your VIN first, but 99% sure). You could obviously buy a replacement from the dealer, but that'd be $$s.
Overseas Subaru Parts suppliers sell the same factory part for much cheaper. From the supplier below, they are Aus$568 plus about Aus$100 postage.

A used dash from a wrecker is also an option of course, but you'd have to ring around to see who has one. But you could be in the same boat in a year or two if they're almost as old as your current one.
I'm not even sure I want a brand new one, knowing I'll be in the same boat again in 5-7 years. So I think getting mine recovered in a better quality material is the way to go. It probably won't match the Subaru pattern that the factory vinyl had, but oh well.
