Only some 5000 NSW residents remain under evacuation orders as harsh weather and flood waters ease across the state.
The latest figure from Sunday morning represents a massive drop from Saturday evening when about 37,000 remained under evacuation orders.
In the 24 hours to 12.30pm Sunday, the State Emergency Service had responded to 317 calls for help and performed 15 flood rescues.
That brings the rescue total to 482 since the floods began on June 27.
"A lot of our jobs at the moment have been animal rescues, medical assistance and resupplying the communities that are currently isolated," an SES spokeswoman said.
Federal relief payments of up to $1000 are now available for residents of 29 local government areas, while NSW residents are being urged to donate money to GIVIT so help can be better coordinated.
The federal government says $340 million in aid has gone out the door so far.
Payments of $1000 per eligible adult and $400 per eligible child are available to people impacted by the flooding.
About 105,000 people have the green light to return home but have been warned to emotionally prepare for what they'll find and to reach out for help from neighbours.
The SES is hoping to get the current number of people under evacuation orders down to zero before the weekend is out.
Flood-affected residents returning to properties should wear PPE, boots, gloves and have sanitiser handy.
As rain returned in areas across the state, including Sydney, authorities warned of several road closures and public transport disruptions due to flooding.
Wet and windy conditions across eastern NSW were expected to begin easing on Sunday before potentially picking up again on Wednesday.
Some 37 Victorian emergency personnel also travelled to NSW over the weekend to help with the rescue and clean-up, taking the total number of crew from the state to 94.
On Sunday, NSW Emergency Services Minister Steph Cooke said the GIVIT donation hub would allow the NSW government to better direct donated money for flood victims.
"By donating through the official channels people can know their generosity is going directly to those who've been hit hardest by the flooding," she said.
Of 2285 premises already examined, 239 have been deemed not habitable and a further 973 require repairs.
The NSW Department of Primary Industries also gave beekeepers another seven days to move hives to higher ground in flood areas.
NSW is battling an outbreak of hive-destroying varroa mite, with a stop on all hive movement.
In the Hunter, lower Hawkesbury and Blue Mountains regions, roads remain cut in multiple towns and train services are affected.
The T1 Western, Blue Mountains and Hunter train lines are not operating between some stations, and the Parramatta River ferries are offering replacement transport between some stops.
