You wpuld not want to prospect in the Otways - although reported I doubt if even a single ounce was produced in total. SteelPat gives good advice - Steigliz would be closer but most is restricted - also Meredith, Elaine, Bamganie, Ballark, Morissons, Dolly's Ck, Mt Egerton.....Dolly's Ck turns out a few nuggets
The coastal strip is a dead loss - no gold production because the rocks are too young and too far from gold sources.
