Australian trade union Collieries' Staff and Officials Association (CSOA) said on Tuesday its members voted to extend their work stoppage at diversified miner South32's Appin mine for one more week.

"Members met yesterday and voted to extend their current work stoppage by a further week, given that parties had failed to reach agreement on at their most recent meeting on Friday, 18 August," CSOA Lead Organiser Belinda Giblin said.
