The gardens owe their origin to the Cumberland Planning Scheme (1946?1951) which set aside the area along the banks of the Duck River for recreation. Both before and after the scheme, the council dumped rubbish and sewage along the banks and in brick and tile clay-pits for many years. In July 1968, Black presented a detailed report to the council on proposing a mixture of sporting grounds and intensive cultivation of the Duck River parklands. Black envisaged a series of gardens representing national styles from around the world. This vision was later reduced, though some elements survived, including the Japanese gardens and lake, the formal gardens and reflection pool, and the different Australian habitats.[2]
