Unitedphil, I don't live over that side of the country so I can't help with maps but you'll find most information online. In WA we access our Mines Department. I don't know what you have in your state but I'm sure you'll have a publicly accessible site for access by persons holding a Miner's Right. In all the years we've been looking for gold we've never asked for advice on locations because nobody is going to tell you where they get their gold
The other option and perhaps your best one is to download Australian Geology Travel Maps (Trilobite). A small annual subscription will give you access to gold and gemstone locations across the country as well as detailed maps.
