Hey mate,
CRABs hasn't been active (not that it ever got that active) for over a year now since I moved down to the Hunter region.
There is however a group in Grafton called Brewmasters, contact Brew Matt on here for info
They usually run brew meets once or twice a year and camp on someone's property.
Also they do a tasting night every year for the Grafton show, judges come from a bunch of breweries across north NSW to SE QLD, it's always a great night.
If you want ingredients in Coffs, Country Brewer in Toormina is your best bet, the shop in town is purely kits and turbo crap for distilling.
Cheers,
Daniel
