Tas Oak (there is actually no such tree as Tas Oak, just a vague grouping of eucalypt species...bit of marketing ********) is fine, I use a piece of Blackwood and had no problems, I am going to make a Huon Pine mash paddle just to be flash.
Most timbers have mild antibacterial properties and will be fine to use. The color stops coming out of the wood after a couple of uses and is just tannins.
Do your bit to help:
The Tasmanian economy (if you don't you will have to support us with more GST dividends from other states, thanks WA and QLD),
The Forest Industries (we need it due to the lying Greens and sell out Labor governments both Fed and State)
Use a renewable resource with low carbon footprint...unlike Aluminium, Stainless steel, plastic etc.
My continuing employment
I do have a Forest Industry affiliation!!
Cheers
