Mosquito management at Sydney Olympic Park

Sydney Olympic Park is one of a number of places along the Parramatta River that contains saltmarsh meadows and mangrove forests – these valuable ecosystems are natural breeding habitats for saltwater mosquitoes (Aedes vigilax). Saltwater mosquitoes are active during the warmer months, and their population peaks during summer and early autumn, following rainfall and unusually high tides.

Mosquitoes are most active during warmer months. You will see Sydney Olympic Park Authority-managed aerial helicopter treatments and ground-based spraying taking place within the tidal wetlands of Newington Nature Reserve and Badu Mangroves between November 2021 and March 2022. Spraying is organised to take place just after a high tide event or after heavy rains, when peak hatching occurs.

For more information on the program and for the spraying dates and times, please visit the Sydney Olympic Park Website.

Community information sessions

Sydney Olympic Park Authority is hosting two community information sessions to increase awareness of the mosquito management program. It is also an opportunity for community members to ask questions. The session will provide a brief introduction to mosquito diversity and ecology. It will also highlight the Sydney Olympic Park Authority’s mosquito management program and the treatment details.

Two sessions will be held in November 2021. Pre-registration is required for these sessions. Once you have registered, you will receive a confirmation email, with a link for the zoom session.

The information will be provided by Associate Professor Dr Cameron Webb from the University of Sydney – NSW Health Pathology. The Sydney Olympic Park Authority’s Manager Wetlands Dr Swapan Paul will facilitate the session and there will be an opportunity to ask questions.
