A national technical outage brought sales to a standstill at the busy Mackay city store this afternoon.
ZDNet understands the glitch didn't make its way to all stores, however, with some operating as usual.
Woolworths confirmed the outage in a social media post, saying that "an IT issue impacted registers in our supermarkets for a short period of time this afternoon".
SBS journalist Lydia Feng said she was shopping at a Woolworths in Balmain, in Sydney's inner west, when the registers went down about 4.15pm on Monday. "We apologise for the inconvenience this caused our customers". "Thanks", the reply to many reads.
News Corp Australia counted at least 10 abandoned trolleys and baskets in the store.
INITIAL: MAYHEM has erupted at Woolworths stores across the Mackay region as a national technical outage shuts down stores.
Others have been told to leave the stores.
Shopper Sharni was among those asked to leave her groceries behind at the Hampton Park store in Melbourne.
The supermarket giant has taken to Twitter to confirm the IT issue has since been resolved.
