Sydney Green Plaques
Between 1984 and 1988, the Royal Australian Historical Society, in partnership with the City of Sydney and the State Bank of New South Wales, produced 101 commemorative plaques that were installed around the city's CBD on historic sites and buildings to commemorate the Australian Bicentenary. The green metal roundels were manufactured by Arrow Engravings. The green chosen for the plaques was the colour of the State Bank's branding.
A number of the original plaques were lost or demolished over the years and a program to replace these has commenced.
