A common practice, when the tree is looking a bit shabby, or perhaps bug-infested.
I mean these are in the ground... they have very deep root, and the fire refreshed the plant. Bushfires happen naturally in many places where you find these small 'trees'.
The one my dog was hunting snake in is overdue, and as everything is really green, here, and I also have a big pile of fallen plant matter, like branches and weeds,, etc, I will probably set fire to my little stack, as they are called, and that Black Boy.
Digging post holes and working with concrete is no fun, and so people try to take the easy way. They dig narrow holes and only use a little concrete or even none at all. That's how you end up with a leaning fence. The holes should be 3 times the size of the post. So, if it's a 4X4 post, the hole should be 12 inches in diameter. The post hole should be 2 1/2 feet deep. The bottom 6 inches should be gravel for water drainage. With the post in the hole and level, the hole should be filled with concrete and then built up at least 4 inches above ground level to provide for water runoff. And of course, it should be a pressure treated post. Done that way, it should stay straight and resist rot for a long, long time. And corner posts should be 6X6. Posts with a gate attached should be 6X6 as well.Tassy has a lot of wooden fences, here in Adelaide Colorbond (colored galvanised & corrugated iron) is the go. In George Town I would need to have fence posts 60cm/2' down and every second or third at least 900mm/3' or even more, the clay moving (swelling & shrinking) and being so soft when wet. Seen plenty fences leaning more than a bit in that part of town.
