The Warriewood Wetlands are swamps on the flat lands between the Warriewood beach and the Ingleside/ Elanora Heights, about 45 minutes drive north of Sydney. There is a large number of bird species recorded at the Warriewood Wetlands.
The birds seem to distinguish between 3 distinctive parts in the Warriewood Wetlands:
The local Guringai Aboriginal people would have found these swamps rich in food supplies like fish, birds, plants and naturally fresh water.
From the Irrawong Waterfall flowing from the escarpment, the water flows down the wetlands as Mullett Creek and is filtered through this roots system providing a superb ecosystem to the flora and fauna living there, before it flows to the Narrabeen Lagoon. Lagoons and swamps are typical of the northern beaches and east coast of New South Wales.
Narrabeen Creek flows through the middle of Warriewood Valley, and Mullet Creek marks the southern boundary of the Warriewood Wetlands. The maps created in the early 19th century mark Warriewood Valley, as a “swamp”. Warriewood is now located as a post coded suburb 2102 on Sydney's northern beaches, between Mona Vale and North Narrabeen, in the Northern Beaches Local Government area.
