The wet and windy weather battering parts of New South Wales since the weekend will continue today, although conditions are expected to ease later on.
A large low pressure trough has brought heavy rain, strong winds and dangerous surf conditions from the mid north coast to the south coast and flooded at least five homes.
The rain is already easing in Sydney, but a severe weather warning remains in place for the Illawarra and south coast regions.
More than 150 millimetres of rain has been recorded in areas around Bowral, in the southern highlands, in the 24 hours to 9:00am on Wednesday.
State Emergency Service (SES) Incident Controller Greg Murphy says a number of flood rescues were carried out in the southern highlands yesterday afternoon.
"There were people in floodwaters trapped or isolated," he said.
"Often it's a case of getting people across floodwater back to their homes.
"We also had some incidents yesterday where animals, mainly horses, were in floodwaters."
The SES says five homes in Shoalhaven Heads, near Nowra, were inundated overnight.
David Webber from the SES says crews will be out helping to clean up during the day.
"The Bureau of Meteorology still have a severe weather warning out currently for the Illawarra area," he said.
"So we will be monitoring, doing reconnaissance for that area, other impact areas, and of course responding to any requests for assistance that come through.
"We've had a total of over 700 since the start of this event.
"Most of our calls are around leaking and damaged roofs and sandbagging."
The Bureau of Meteorology has forecast moderate flooding on the Nepean River at Menangle this morning.
The SES is also assessing the flood damage in Goulburn, in the southern tablelands.
It says the village of Towrang is also likely to remain isolated for another 24 hours, due to high flows in the Wollondilly River.
Around 130 millimetres of rain has been recorded in the Goulburn area since Monday but conditions have eased considerably.
The region controller Tony Casey says crews are checking low lying areas.
"Both rivers that run through Goulburn, the Wollondilly and the Mulwaree appear to have peaked late yesterday," he said.
"We've got reconnaissance teams out on the ground at the moment just confirming where the rivers are at this stage.
The SES says it expects to be able to lift a flood evacuation warning for parts of Goulburn this morning.
