Hi RB, and welcome to Vic.
Would help to know what you are planning - detecting, high-banking or panning (assuming that you're after gold).
Also, if detecting, what machine are you using.
As Winter leaves, many of us Vic thin-bloods will start hitting the GT more regularly, so it may be a good idea to catch up on some of the posted meet-ups.
If you are detecting and want to go it alone, then buy some John Tully or Doug Stone maps from a prospecting store of places like: Avoca
do, Ballarat, Bendigo, Castlemaine, Maryborough, Dunolly, Kingower, Inglewood, Wedderburn or Creswick (if you have a SDC) etc.
Just remember that you can't take gold back across the border, so I'll have to post it to you
