Starting on Thursday, the first hour of trade on Tuesdays and Thursdays will be for emergency services and healthcare workers including doctors, nurses, paramedics, hospital and ambulance staff, police, firefighters and emergency service workers who hold an AHPRA card, have a workplace ID or are wearing their work uniform.

Monday, Wednesday and Friday Coles community hours will continue to be dedicated to vulnerable and elderly customers who hold a government-issued Pensioner Concession Card, Commonwealth Seniors Health Card, Companion Card, Seniors Card, Disability Card and Health Care Card.

Coles Group CEO Steven Cain said the move will help even more Australians access the essential groceries they need.

"In the past week we have seen community hour help vulnerable and elderly Australians access essential grocery items during this challenging time. We are now extending this opportunity to those Australians who are protecting our community and keeping us safe," Mr Cain said.

"We know these workers are incredibly busy and hope that providing them with a dedicated hour at the beginning of the day to shop will make their lives a little easier and support the vital work they are doing every day."

"We are also incredibly proud of our team members in-store who are working hard to get stock on to shelves as fast as possible, create a safe place to shop, and provide our customers with great service. We ask that our customers continue to show them kindness and patience."
