A national review of the discount department chain was announced in February to determine whether any stores would face closure amid the challenging retail climate.

Three stores in Sydney: Chullora, Auburn and Fairfield, will continue trading until they close in January 2020 after an agreement was reached with the landlords.

A Big W spokesperson could not confirm whether the Wagga store could be among future store closures.

Managing director of Big W David Walker said these decisions were not taken lightly and he "regrets" the impact the closures will have on those team members.

"We would like to acknowledge the support of the communities of Chullora, Auburn and Fairfield and the hard work and commitment of our store team members," Mr Walker said.

"Supporting our team remains our priority and we are committed to doing the right thing by them.

"Over the next six months, we will support our team and explore redeployment opportunities with team members who choose to continue their career at Big W or with other Woolworths Group brands in the months ahead."

This follows an announcement in April that the company intended to close up to 30 stores and two distribution centres in Warwick, Queensland, and Monarto, South Australia, over the next three years.
