The park was the source of the colonies drinking water for many years following the polluting of the Tank Stream by early settlers. The Macquarie Marshes were a protected area and the park formed a natural catchment area for them. In due course the water of the marshes became unfit for human consumption and once a new water supply had been secured, the area was turned into a park. The ceremony marking the federation of the Commonwealth of Australia was held in the grounds and a rotunda, constructed in the early 1990's now marks the spot where this took place. The Rotunda in Centennial Park built over the place where the Australian Federation ceremony was held.
Centennial Park is the largest open green space in Sydney.
