SES advice

The State Emergency Service advises people to:

  • Move vehicles under cover or away from trees.
  • Secure or store loose items around your home, yard and balcony.
  • Stay at least 8 meters away from downed power lines or potentially live objects, such as fences.
  • Trees that have been damaged by fire are likely to be more unstable and more likely to fall.
  • Report downed power lines to Ausgrid (131388), Endeavor Energy (131003), Essential Energy (132080) or Evoenergy (131093) as indicated on your electricity bill.
  • Do not drive, ride or walk through flood waters.
  • Stay away from streams and storm drains.
  • If you are trapped by a flash flood, seek refuge at the highest place available and call 000 if you need help.
  • Be aware that rainfall runoff in areas affected by fires may behave differently and be faster. It may also contain debris such as ashes, dirt, trees and rocks.
  • After bushfires, heavy rains and loss of foliage can make the ground soft and heavy, increasing the risk of landslides.

Flood deaths in Lismore

As Sydney and the south coast brace for wetter weather, specialist emergency service teams are on their way to northern New South Wales to rescue and recover flood victims.

Interstate Emergency Services volunteers are heading to Lismore, where more deaths are feared after the body of an 80-year-old woman was found in her flooded home on Tuesday.

Another man who disappeared into a sewer on Sunday has yet to be found and many more are missing.

Lismore Mayor Steve Krieg said Tuesday the community must prepare for additional deaths as interstate teams arrive to search flooded homes.

“I’m an eternal optimist, and I pray the numbers are low, but [the two deaths] that’s a conservative estimate,” he said.

“The number of people rescued, officially and unofficially, is mind-boggling.”

The grim recovery mission comes as residents of nearby Ballina, including the 55 patients at Ballina Hospital, were ordered to evacuate due to rising waters on Tuesday evening.

Health officials said the evacuation was on the advice of the local police commander, out of an abundance of caution to protect the health and safety of patients and staff.
