Sydney's Bicentennial Park is just west of Concord West station (about 15Kms from Central station) and is adjacent to Sydney Olympic Park. The Badu Mangrove boardwalk enables people to walk through the largest remaining mangrove ecosystem along the Parramatta River.
A coastal saltmarsh is a salt-tolerant plant community that lives between high and low tide, often behind mangroves.
On our visit, the air had a smoky haze from hazard reduction burning in the Blue Mountains the previous day.
The parklands contain diverse habitats for many plants and animals that are significant locally, nationally and internationally. These include rare saltmarsh communities, breeding populations of insectivorous bats and endangered Green and Gold Bell frogs. Species of migratory birds protected under international treaties also often roost and feed in saltmarsh during their stay in Australia.

The Brickpit Ring Walk
The Ring Walk, is 550 metres in circumference and is 18.5 metres above the floor of the Brickpit.
The original audio has packed it in, but the informative panels around the side are in good condition. They give a history and geology of the Brickpit and information on the frogs.
My thanks to Jean B. for leading us on this interesting walk
