"We can confirm that an IT issue impacted registers in our supermarkets for a short period of time this afternoon".
UPDATE 4.50PM: STAFF at Wooloworths Caneland Central are unloading shopping trolleys full of stock abandoned at registers this afternoon. "We apologise for any inconvenience caused".
"Registers are offline so customers are standing in queues with baskets of food that they can't buy", she said.
Dozens of customers earlier took to social media to report the issue.
A security guard was also stationed at the closed doors to turn shoppers away.
"Everyone was walking out of the store empty-handed. We were all offered a box of chocolates".
Woolworths told Daily Mail Australia registers were back online just before 5pm.
Shoppers took to Facebook across Australia to complain about the outage and accused the supermarket chain of "ruining dinner plans".
Woolworths has close to 1000 stores in Australia, though it's not known how many stores were affected.
Woolworths has apologised after a technical glitch left shoppers across the company in the lurch.
Woolworth confirmed that all stores were now open, even if they had temporarily pulled down their shutters during the outage.
News Corp Australia has contacted Woolworths for comment.
