You burn wood April to September!!!?...it's 29c here today a drop from April which had highs of 30's building a carport just now metal is bloody hot...Only burning less than a stere per year (we're only here April to September) the work cutting it up is minimal and they don't come thick round here. Dunno why.
But yes cutting up a 18" log would be like a yule log.
20 cubes a year at those prices? wow, that is a lot of dosh!
