South Australian suburban supermarkets will be allowed to open their doors on Anzac Day for the first time in the state’s history this year.

Supermarkets will be allowed to open from midday this Saturday, but would have to remain shut throughout the morning in-line with CBD trading restrictions.

State Treasurer Rob Lucas will use his ministerial powers to push the change through for this year, while also extending the 24-hour trading exemption given to SA shops last month.

The changes in trading regulations are aimed at broadening shops’ trading hours to better allow for social distancing.

However, critics of the change have pointed out that many supermarkets had been closing early since the trading exemptions came in to replenish stock in their stores.

The special trading exemption only applies to this year’s Anzac Day, while 24-hour trading will now be allowed through until May 19.
