A nationwide technical outage has shut down Woolworths' registers, forcing stores to close their doors.
"They've told everyone just to leave their food and leave the store".
A national technical outage brought sales to a standstill at the busy Mackay city store this afternoon.
Shopper Sharni was among those asked to leave her groceries behind at the Hampton Park store in Melbourne.
"Registers are offline so customers are standing in queues with baskets of food that they can't buy", she said.
A Woolworths spokeswoman said the registers were coming back online now.
Checkouts were unavailable in hundreds of Woolworths supermarkets
At Haymarket, in Sydney, staff shut the store and were turning people away, telling them to "come back in about an hour".
"We apologise for the inconvenience this caused our customers", the spokesperson said.
Shortly after 4pm, the issue began affecting all registers across the country.
Registers have shut down with stores unable to make sales.
The supermarket giant has taken to Twitter to confirm the IT issue has since been resolved.
The ABC reached out to Woolworths for comment.
