On the morning of Tuesday 21st March, local residents of northern Sydney will head to the Field of Mars Reserve, East Ryde, to see if they can find local water dragons and help with water quality testing and bush regeneration.
The Dragons of Sydney project is an initiative run by the National Parks Association of NSW (NPA) in partnership with Macquarie University to conserve Sydney’s urban Water Dragons through revegetation and citizen science.

The Australian Water dragon (Intellagama lesueurii) is a large lizard species common along the eastern coast of Australian ranging from Queensland to Victoria. There are two subspecies described: the Eastern Water Dragon (Intellagama lesueurii lesueurii) living in the northern extent of the range, and the Gippsland Water Dragon (Intellagama lesueurii howittii) living in the south1. The males of this species are larger in size and will defend a territory, displaying a bright red chest coupled with head-bobbing and arm-waving to communicate to other males to stay away. Females will regularly mate with multiple males to ensure genetic diversity of her eggs; a single clutch of eggs may have 2-3 different fathers2 divided between 6-18 eggs.
Thursday’s heat did nothing to deter 20 enthusiastic young volunteers from taking part in the first of a series of community events at Bradleys Head Reserve aimed at helping the area’s Eastern Water Dragons.
The event was organised as part of Dragons of Sydney Harbour, a new initiative run by the National Parks Association of NSW (NPA) in partnership with Taronga Zoo, Conservation Volunteers Australia, Macquarie University and Greater Sydney Local Land Services. It seeks to conserve Sydney’s urban Water Dragons through revegetation and citizen science.
