Representatives of Legacy lay wreaths on the eve of Anzac Day at Woronora Memorial Park's Military Memorial.
The remembrance ceremony was led by Stan Mackie, 84, of the St George Sutherland division of Legacy.
Mr Mackie is the oldest living ex Junior Legatee in metropolitan Sydney and first enrolled with Legacy when he was ten-years-old.
He was joined by fellow former Junior Legatees Jim Slaven and Elaine Harridge. Both Mr Mackie and Mr Slaven were children when their fathers were killed while serving in World War II.
They were joined by Joanne Muller, Chair and Carol Provan, Board Member and Carolyn Dowe, Senior Manager at Southern Metropolitan Cemeteries NSW.
Carol Provan, who is also a Sutherland Shire Councillor, spoke of the important role of Legacy which currently supports more than 80,000 widows or widowers and partners and 1,800 children and dependants with a disability including around 1,300 in the St George area.
"Legacy is what it is because of history, from the promise of one digger to another in trenches long ago, to mates as aircraft took off never to return, to ships on convoy and comrades who fought and died as their vessels sank in the Defence of our Nation, 'Look after my kids, my loved ones... be there when I cannot,' " Councillor Provan said.
"Legacy will never forget, and in grateful thanks, the children of our Nation remain part of the building blocks for tomorrow's generations who will recite those words both today and in another centuries time hence, 'Lest we Forget.' "
Cr Provan acknowledged the support that Woronora Memorial Park's Operation's Team has made to Legacy by donating 6 large buckets of Rosemary to Legacy NSW which helps to make 150,000 sprigs for people to wear on Anzac Day.
The initiative called Operation Rosemary for Anzac Day started in 2013.
