Floods ease in NSW but threat 'not over'

Warnings are expected to be rolled back where safe to do so over coming days, but major flooding is still occurring along the Barwon, Darling, Murray, Edward, Murrumbidgee, Lachlan and Bogan rivers.

With the first weekend of summer and start of the annual cod-fishing season, authorities are urging the public to make safe decisions.

The NSW SES advised staying vigilant around floodwaters, which can carry hidden risks such as underwater currents and debris.

Flooded rivers may contain snakes, spiders, chemicals and sewage, NSW SES assistant commissioner Nicole Hogan said.

"Although the sun might be shining and some river heights decreasing, floodwater may be deeper or flowing faster than it appears," she said.

"Ensure children never play in floodwater."

The warning comes after three children were saved from drowning in the Hunter River at Denman.

One of the children, a 15-year-old girl, had her foot caught in timber debris and was pulled to safety at the last minute.

Meanwhile, members of the Singapore Civil Defence Force were farewelled in Sydney after two weeks helping respond to one of NSW's worst flood disasters.

The team of 16 rescue specialists were deployed in Condobolin, Euabalong, Forbes, Parkes and Wagga Wagga.

"This support has been so helpful for our SES volunteers who continue to respond to the ongoing flood emergency across the state," Emergency Services Minister Steph Cooke said.

"In what is the largest flood response on record, the Singaporean team's expertise as rescue specialists has reinforced our capability in resupply missions, medical transports, sandbagging and search and rescue to protect our communities."

Eight SES emergency warnings remain in place as well as 44 watch and act orders.

In the 24 hours to Friday afternoon the SES responded to 95 requests for assistance and conducted one rescue.
