Melbourne, Australia - Two people died and two others were missing as more heavy rains are expected in the area, officials said Thursday.

More than 500 people were rescued in a flood emergency in NSW, north of Sydney, New South Wales. The area has been hit by heavy rain since Tuesday. Floods exceeded local records set in 1921 and 1929.

News South Wales Prime Minister Christopher Minns said some areas are expected to receive up to 30 cm (1 foot) of rain in the next 24 hours. He said 50,000 people were warned to be evacuated or quarantined by floods and told reporters: "We are preparing for more bad news."

Fire and Rescue Commissioner Jeremy Liew said the body of a 63-year-old man was recovered from a flooded house on a motorcycle in New South Wales on Wednesday afternoon. He added that the coroner will determine whether a pre-existing medical condition played a role in his death.

The body of a man in his 30s recovered from the flood earlier Thursday, police statement said. He was missing while trying to drive through the flooded intersection Wednesday night.

A 60-year-old woman remains missing after being trapped in floods Wednesday night. Police said the SUV was found Thursday.

Police said a 49-year-old man also failed to return home after walking near a flooded road Wednesday night.

Minnes said more than 500 people were rescued from the flood in just two days, and many tried to drive across flooded roads.

Emergency Services Minister Jihad Dib said 330 flood rescues were conducted in the past 24 hours. Helicopters have been used to rescue people in trouble on roofs and balconies.

"In the north-central coast, we're seeing more rain and flooding than ever before," Dib said.

The floods hit communities such as Tarry, Kempsey, Port Macquarie, Coffs Port and Bellingen in New South Wales.

An official said Taree had rained for a month within 24 hours.

“In the Taree area, we have seen communities that have never flooded in recorded history,” said a few.

As of Thursday, 14 evacuation centers have been opened in the area.

Government meteorologist Angus Hines said the low-pressure weather system has stalled in flooded areas since Monday, bringing 60 cm (2 feet) of rain to some places.

"If it's only one day, then go and we'll see some small or medium flooding, but that's not bad. But, this four days of rainfall, we've seen this important, wide, wide and significant flooding event happening before our eyes," Shians said.

Hines said the rainfall was losing intensity on Thursday.
