It is indeed! It's a eucalypt and I think grows quite widely across Aus, Brown Mallee is very beautiful too. (I was living in Adelaide for a few years until recently).
My favourite part of that handle though is the Western Myall, which was given to me by someone I knew there who told me to keep it for something special. I wasn't quite sure why at first, cos frankly it looked like kindling:

Western Myall he told me is a smallish but exceptionally long-lived and slow-growing, shrub-like acacia found in the outback, and apparently heavily protected, so you can't go around cutting down living trees. About 20 years ago a geologist friend of his had been working in northern SA for some months and came across a tree that by his estimate had probably been dead for about 200 years, and was maybe 500-700 years old before that, so brought some of it back.
The age of it, combined with long curing/ageing in the Aussie desert made it just an extraordinary wood to work with. Slightly difficult to describe, but it's extremely heavy and feels beautiful, with a dense, tightly twisted grain, and gorgeous tobacco-smoke colour and chattoyance. It's a stunning wood for handle material.
