Very pretty wood and a very contemporary kit...!
The #53 BlackWood I've got, that had lived and grown in this town, in someone's property, has some resemblance if from the very centre of the log, some people confuse Australian Black-Wattle and Australian Blackwood however, I have also seen other pieces of Australian BlackWood grown is other states that look very different so I would say, there should be some variants of this species throughout Australia...!
Cheers
