About 50,000 people are still isolated across New South Wales after a powerful weather system dumped months of rain in three days.
Record-breaking floods in eastern Australia have killed four people and stranded tens of thousands after days of relentless rain.
Prime Minister Anthony Albanese and New South Wales Premier Christopher Minns visited affected communities on Friday, some of which have experienced their worst flooding on record this week.
Minns praised emergency workers and volunteers, who have rescued 678 people in recent days – 177 of them in the past 24 hours.
“It’s an amazing, heroic logistical effort where, in very difficult circumstances, many volunteers put themselves in harm’s way to rescue a complete stranger,” Minns told reporters.
“Without the volunteers, we would have had hundreds of deaths and we’re in deep, deep gratitude.”
As well as the four victims killed, one person is reported missing.
About 50,000 people are still isolated across New South Wales, the country’s most populous state. Entire towns remain cut off and roads submerged after a powerful weather system dumped months of rain in three days.
Flash floods tore through rural communities, washing away livestock, damaging homes, and turning streets into rivers. Coastal areas are now littered with debris and dead animals.
Authorities have warned returning residents to remain vigilant.
“Floodwaters have contaminants, there can be vermin, snakes … so you need to assess those risks. Electricity can also pose a danger as well,” said Emergency Services Deputy Commissioner Damien Johnston.
Australia has faced a string of extreme weather events in recent years, a trend experts attribute to climate change.
“What once were rare downpours are now becoming the new normal – climate change is rewriting Australia’s weather patterns, one flood at a time,” said Davide Faranda, a climate researcher at ClimaMeter, in comments carried by the Reuters news agency.
The storm system has now moved south towards Sydney, causing further disruption.
Train services, including airport services, were affected by flooded tracks. Sydney airport shut two of its three runways for an hour on Friday morning, delaying flights.
Officials also warned that Warragamba Dam, which supplies 80 percent of Sydney’s water and is currently at 96 percent capacity, may soon overflow.
