Clean-up operations continue in NSW

Provisions, including baby formula, food and medication have had to be ferried to people stranded in the NSW Hunter region.

Up to 2000 people remain cut off in Gillieston Heights and Hinton, near Maitland, heading into the weekend.

About 100,000 homes and businesses, including 60,000 in the Hunter region, are still without power.

The SES still has more than 6700 jobs to attend out of the 16,400 it received when NSW was lashed by wild weather earlier this week.

Flooding, road closures and fallen trees have made it difficult for crews to access sections of the network with homes and businesses still without power on the Central Coast and Sydney's northern beaches.

A house in a precarious position, in the Sydney suburb of North Narrabeen, was safely demolished in a huge operation involving firefighters and police on Friday afternoon.

The house had been propped up by a single tree root after the storms.

Clean-up efforts will continue to be focused in northern Sydney suburbs and the Hunter in coming days, an SES spokeswoman said.
