The death toll from the floods ravaging NSW has risen to four, with three of those people found dead trapped in their cars.
Fears are also held for a fifth person who is still missing.
The family of the first victim has paid tribute after his selfless act as flood waters rose, while police have revealed the tragic circumstances surrounding the deaths of the other three people, who are yet to be identified.

Moto
Farmer David Knowles, 63, was the first confirmed victim of the floods after his property was inundated by the floods in the state’s Mid North Coast.
Mr Knowles had heroically stayed behind at his property near Taree to protect his cattle as floodwaters rose.
His daughter Stacey Hurrell told the Daily Mail that her father’s best friend, Wayne Drury, had led a team of rescuers to the family property.
But instead of taking a spot in the limited number of lifeboats, Mr Knowles asked rescuers to find and rescue his family instead.
“He was a man with the biggest heart,” she said.
“He’d give you his last dollars.”

Authorities were called to the property at North Moto Road, Moto, about 3pm on Wednesday following reports of a body being found.
His body was later found on the verandah. Authorities believe existing medical conditions may have contributed to his death.
Ms Hurrell and his other daughter Roxy have paid tribute to their father, writing: “Dad passed as a hero yesterday, sending help away to save others.”
“He didn’t want to leave his farm on a good day.
“We all couldn’t be prouder of you, Dad.
“We love you.”

But the woman phoned the officer 30 minutes later, saying she was in trouble near Morora Road, Brooklana, about 17km away.
