Mullumbimby and District Neighbourhood Centre has acted on feedback given in conversations with community during the weekly Jam Session and BBQ. They have started with an activity every Tuesday morning teaching opal cutting and polishing in the MDNC courtyard.

Mel Williams facilitates the group and is passionate about everything Opal. Her grandfather mined in Cooba Pedy when she was a child and now, along with her partner, she visits mines in Koroit, Lightning Ridge and Yowah at least once a year. She has been doing this for eight years. Her grandson even calls her the ‘Opaless’.

For those that watch the Popular series the ‘Outback Opal Hunters’ they would be familiar with Isaac the ‘Opal Whisperer’. He is a good friend of Mel. Opal Hunters are unique human beings.
