Northern Sydney NSW SES

Northern Sydney NSW SES NSW SES (New South Wales State Emergency Service) is the combat agency for floods, storms and tsunami

The NSW State Emergency Service (SES) is an emergency and rescue service dedicated to assisting the community. It is made up almost entirely of volunteers, with 241 units located throughout New South Wales. The units comprise of approximately 9,000 volunteer members, who are easily identified by their distinctive orange overalls. While our major responsibilities are for flood, storm and tsunami op

erations, the SES also provides the majority of the general rescue effort in the rural parts of the state. This includes road accident rescue, vertical rescue, bush search and rescue, evidence searches (both metropolitan and rural) and other forms of specialist rescue that may be required due to local threats. Volunteers in a number of isolated communities have been trained as Community First Responders by the Ambulance Service of New South Wales. The Service's trained rescuers also support full-time emergency services during major disasters. The SES also assists other emergency services when they are performing major operations. These services include the NSW Police Force, the NSW Rural Fire Service, the Fire and Rescue NSW and the Ambulance Service of NSW.

NSW SES volunteers across Greater Sydney were kept busy over the weekend as intense rain caused flash flooding. ⛈️

Supported by our partner agencies, crews responded to more than 1,511 incidents throughout Sydney, including 17 flood rescues. The busiest areas were Avalon Beach, St Ives, Wahroonga, Newport, Pymble and Turramurra.

The majority of incidents have been for fallen trees, water coming into properties via ceilings, overflowing drains and gutters, or by flash flood water entering homes. There was also damage to properties from fallen trees, broken skylights and roofs.

While the rain has subsided, scattered showers are expected to persist today and more storms are expected later this week.
