Forgotten Australians Memorial, Royal Botanical Gardens, Sydney

The Australian Federal Government provided $100,000 in funding for memorials to acknowledge the Forgotten Australians. Divided among the different states, this amounted to $16,666 each. The NSW State Government chose to place this plaque at the Twin Ponds site of the Royal Botanical Gardens in Sydney, turning the area into a quiet, reflective space where people can come to remember and acknowledge the experiences of people who spent their childhood in State care.
That is one interpretation. The other is that the memorial is hidden away, continuing a tradition of marginalising this aspect of Australia's history.
The memorial plaque reads:

For Forgotten Australians In this place, we remember the many thousands of NSW children who grew up in care in the decades leading up to the 1990s – in orphanages, in Children’s Homes and foster homes, in institutions. We remember the lonely, the frightened, the lost, the abused – those who never knew the joy of a loving family, who suffered too often at the hands of a system meant to provide for their safety and wellbeing. We rejoice in their courage and strength. This corner of the Gardens is dedicated to their memory.Erected by the Australian and NSW Governments19 September 2009
