I have been looking for gemstones also so this forum is perfect for me.
I have had a little bit of luck finding Olivine around Mortlake Victoria. I have also had the chance to go to Daylesford Vic. Found a few bits of cistine. Also have worked the beaches up and down the Great Ocean Road. Always up for a weekend outing with my partner or the family. I love this state. It is small in size but big in adventure.
