I’ve known this tree for about 30 years. It hasn’t changed a bit, half dead when I first saw it, half dead today.
Allocasuarina luehmannii has a broad distribution in the drier parts of southern and eastern Australia often on sandy soils. In Victoria the most fertile part of its range has largely been cleared for wheat growing. So there are far fewer than there used to be.
It is a hard wood. In fact, according to the not always reliable Wikipedia, it has the hardest wood in the world. Black Cockatoos are fond of it, they eat the seeds.
This particular tree sits nicely against the sky. I have photographed it often. This time at sunset.
