That was buying firewood permits off NSW Forestry in the broader region around Canberra, which I looked and they're still doing at $16 per tonne (albeit only in the further away forests at this point). They give areas you can pick firewood from after logging operations, you're just not allowed to fell trees. You do have to be able to go out and saw it then haul it back yourself. If you've got a current collection area near you it's a very cost effective method, even if you have to drive a fair way it still works out cheaper than buying it elsewhere.
