That would be Tasmanian Blackwood (Acacia melanoxylon), someplace is Southern Australia / Tasmania. Looking at the forest, more likely Tasmania. The Holden Ute is a dead giveaway.
The tree is generally known as "Poor Mans Koa", as it's a close relative of Hawaiian Koa.
Coincidentally, I've been sawing the same wood here in NZ. Not old forest grown trees as sweet as that, but some farm forestry / shelter specimens that were starting to succumb to the salt spray where they were growing. Owner have cut a bunch down, but couldn't find anyone local to mill them.
Wife's cousin used to work for the guy, and had been offered them for firewood, "take them away before they rot". "Hang on, I know someone with a sawmill". So we ended up sawing them for shares of the wood, win win.
Logs had been on the ground a year (not ideal) and weren't as big as that old forest one, basically only one ~12ft log from each tree.
Wayne wanted a table for his "man cave", so we hooked him up with a 3" live edge plank.

A load to be hauled home behind the little Toyota
And it's out back drying now.
The landowner is a nice older gentleman. He knows it valuable furniture wood, and has professionally made furniture made from trees he's cut previously, so we did a fair deal. He has a stack similar drying in his shed, and the other guys that helped took some home too.
He also has another ~6 decent trees to take out
And yes the wood is fairly valuable, even with these younger trees. I don't know if it's worth enough to haul out on my shoulders, but the 6" wide boards in that drying stack should easily sell for $50+ each
