I'm on the hunt for dyes tomorrow and I think it was you who recommended an old bloke in the gap who sells wood turning supplies. So thanks for that too!
Yes, they sell the U-beaut water based dyes in a 7-colour pack.

Here's a link to their very archaic site:
https://www.woodturningsupplies.com.au/

Site navigation is horrible. The U-beaut dyes are under "Polishes & Adhesives", Fifth item from the bottom.
