Two stores in Sydney - Town Hall and Kellyville North - have already had the screens fitted, and other stores will follow suit in the following weeks. The move is designed to help protect both Woolies staff and shoppers from the spread of the virus.
Woolworths managing director of supermarkets Claire Peters said: 'Our stores remain open and we will continue to stand by the Australian community through this health crisis.
'As our team members continue providing for the community, we will do everything necessary to uphold public health and safety in our stores.
'We know it’s not always easy to maintain social distancing at our checkouts, so we’ve started installing plexiglass screens as an additional safeguard for our team members and customers.
'We thank our customers for their understanding as we work through these challenging times together.'
Woolworths stores across Sydney will also be given more security guards to help protect shoppers and staff, and on Saturday the supermarket announced a new ‘trolley rule’ - asking customers to keep a trolley’s length between themselves and other shoppers at all times.
