The five inmates donated artworks which were auctioned on Facebook, raising a total of $1410.

Corrective Services NSW launched the auction on February 18 and when the hammer went down at 11am on February 21, the artworks had attracted 55 bids.

"Like the rest of the community, the inmates at Macquarie have been really affected by the bushfires, floods and drought and the impact these extreme weather conditions are having on the Australian people," Macquarie Governor Brett Lees said.

"This was an opportunity for them to help contribute to the relief and rebuilding efforts and to show they care. We're pleased and proud to be able to donate this money to Foodbank NSW on their behalf."
