Crisis talks have been held overnight between ‘essential' industry groups and the federal government, as businesses try to deal with widespread supply chain issues. 

Supply chains of essential services have been impacted by coronavirus-induced staff shortages, forcing major retailers to enforce product limits on several items. 

The Australian Health Protection Principal Committee released advice yesterday that staff in essential services would be able to continue to work after an exposure provided they return a negative RAT test. 

Work is also under way to expand the advice to other essential sectors such as medical suppliers, aviation, childcare and education.
