South Australian shoppers should expect to see police monitoring supermarkets as the state goes into lockdown at midnight.
Police Commissioner Grant Stevens warned that officers would be assisting supermarket staff on Wednesday afternoon in a move to avoid panic buying.
Shoppers have already begun queuing in long lines to do their grocery shopping after the lockdown was announced earlier on Wednesday.
Mr Stevens said it would be a “particularly challenging time” for supermarket and retail staff and asked shoppers to be patient.
“There is no need for people to rush to supermarkets, and if you do go shopping this afternoon, you should expect you’ll be managed by staff, and police will be on standby to attend,” he said.
“If we do see any civil disorder, we will be taking action. There is no need to be panic buying.
“Supermarkets will remain open.”
All residents across the state, with the exception of some essential workers, have been told to stay home for the next six days as of midnight on Wednesday.
All non-essential businesses will be closed, while some essential services – like supermarkets and medical services – will remain open.
Grocery shopping is one of the few reasons South Australians can leave their properties during that time, but only one person per household can go each day.
Mr Stevens said it was expected that people did the right thing and abided by the “extreme level of imposition” to help police do their job.
“Policing can only provide so much in regards to improving a safe environment for the community. It relies on the community doing the right thing and supporting each other,” he said.
“Clearly, if you’re out during these six days, you should have the ability to justify the reason for your travel. We will be out there making sure people do the right thing.
“If you deliberately disobey these restrictions and ignore that advice you’ve been given, then you should expect we’d take action.”
Panic buying began on Monday after Premier Steven Marshall announced tougher restrictions in response to the Parafield cluster.
Toilet paper was seen flying off shelves at stores across the state.
