I do know of one battery still operating, cant remember exactly, think it was around Castlemaine somewhere. Several small mines that operate today in the GT truck in their workings and use it, maybe touch base with a few of the smaller mine operators. Alternately call Fosterville Mines (Kirkland Lake Gold) and ask them if they can help or steer you
Sovereign Hill Ballarat has a working battery, other than that there are 6 remaining State Batteries in Victoria but I don't know if any are still working - they are Creswick, Maldon, Wedderburn, Rutherglen, Bright and Mt Egerton.
