Residents in NSW's mid-north coast have been evacuated overnight ahead of more rainfall, as the state government announces funding for flood-affected primary producers.
The State Emergency Service ordered residents in low-lying properties in Croki to evacuate by 2:30am on Saturday, including people who live on Barton St, Ferry Rd and Reid St.
The Bureau of Meteorology warned flooding is possible near Croki about noon on Saturday during high tide, due to flooding around the Manning River, as dozens of flood warnings remain in NSW.
The warning comes as Deputy Premier Paul Toole announces primary producers can access $15,000 immediately through the Commonwealth-State Disaster Recovery Funding Arrangements.
Grants of up to $75,000 are available for primary producers in disaster-declared local government areas.
"We know it's going to be a long road to recovery for our farmers, however this funding means they'll have access to immediate support as well as in the crucial period of rebuilding ahead," he said on Saturday.
Six deaths have been confirmed in the state's floods, the most recent a man believed to be in his 40s whose body was found near Terragon, south of Murwillumbah, on Friday afternoon.
Meanwhile, there are fears the Hawkesbury River could again peak at a moderate flood level near Wisemans Ferry on Saturday afternoon.
The SES is warning the river, northwest of Sydney, could hit 3.5 metres about 1pm with the high tide.
The weather bureau has also issued a moderate flood warning for Tuggerah Lake, north of Sydney.
The SES says moderate to major flooding is possible along the Hawkesbury and Lower Nepean Rivers from Sunday with more rain forecast.
Over the next four days parts of NSW could see up to 100mm of rain and parts of the Hunter up to 150mm, with severe thunderstorms, heavy rains and damaging winds forecast, the BoM said.
"We are not past the danger period yet. The rivers are very high, fast-flowing," NSW SES Commissioner Carlene York said.
Further rain over the weekend falling in saturated catchments could cause renewed river rises in areas already devastated by flooding.
Cash management providers Prosegur and Armaguard have delivered cash to Casino, Byron Bay and other towns around northern NSW as electronic payment systems were taken out of action and ATMs ran out of notes.
About 400 NSW Rural Fire Service, Fire & Rescue NSW and Australian Defence Force personnel are joining locals to start the clean-up effort.
"The immense scale of the flooding is unprecedented and we are putting equally unprecedented resources into the significant clean-up and long-term recovery effort," said Emergency Services Minister Steph Cook, who will soon take on the role of Flood Recovery Minister.
Concerns have been raised about the depth of the government's preparation, resourcing and response to the disastrous floods, with the NSW Premier acknowledging on Friday it was likely mistakes were made.
Those will be identified when the government conducts its reviews and the premier has pledged to "resource every level of government to a level that will provide protection to the people of our state".
The SES has begun giving the all clear for evacuated residents to return home after Sydney dodged the bulk of the rain.
Thousands had their power returned on Friday, but Endeavour Energy estimated it could take several days for flood-damaged electricity infrastructure to be assessed.
