G'Day Green,
It does seem to look like your situation is unique so it may be best to just get online to the ATO and look at the legalities etc, there is a heap of help there as I did do this a few years ago only to find SWMBO saying if I went this path it's bye bye :angry-banghead:
Eh mate if you can get over to SA you are welcome to come here for a weekend and i can show a true moonshine style where only the best is made and everyone that tastes it keeps saying to me to go legit :handgestures-thumbupleft:
I can show you how to make brandies etc as it just so easy once learns how to do it :handgestures-thumbupleft: right, we are all here to help you out so you can open your eyes to this craft :handgestures-thumbupleft: where the best drop is made in he comfort of your own space.
Cheers Bryan
