NSW Floods

The declaration gives the federal government power to intervene and deploy resources.

It is a legislative power that Morrison sought after the 2019-2020 bushfire crisis.

Morrison is also set to outline more money to help communities recover from floods on the east coast when he visits Lismore today, as government ministers expect anger from residents whose lives have been upturned.

The federal government has been criticised for the pace and scale of its response to the floods.

A woman was reported missing at Burringbar, south of Murwillumbah in NSW, overnight on Thursday and police said a body was found on a flood-affected property about 8:00am on Friday.

Between 500 and 740 millimetres of rain was recorded in NSW's Tweed River valley in the 24 hours to 2:00am on Friday, after which it began to ease.

The main areas affected are around Murwillumbah, where residents were forced to seek refuge in ceiling cavities and on the roofs of their homes, and in Lismore, where the Wilsons River has reached 11.6 metres.
