Hope amid devastation: Australians found safe, but dozens still missing

Five Australians have been located safe in the wake of the catastrophic floods that have ravaged Nepal's Himalayan border region with China, offering a glimmer of hope as the desperate search continues for 38 others still unaccounted for.

Four more Australians were confirmed safe on Wednesday, with one found in Nepal and another in China, while three others were located outside the disaster zone, according to a report by the ABC. The ABC understands that those confirmed safe on Wednesday had not had contact with their families since the flood, and their welfare could not initially be confirmed.

The encouraging news comes nearly a week after torrential rains triggered catastrophic flooding and landslides that have killed more than a thousand people and left thousands more missing, according to officials and state media reports.

Rescue efforts and challenges

Nepal's Prime Minister Balendra Shah reported that 279 workers had already been rescued from hydropower projects, but the disaster management authority said at least 639 people remain stranded at these facilities, with rescuers attempting to reach nearly 300 workers believed to be trapped inside tunnels.

"Our first rescue observation at Trishuli Hydro Power plant shows that it is not humanly possible to go into the tunnel," said Asish Gurung, a mountain guide assisting in the rescue, as told to Reuters. "We need machines like bulldozers and excavators ... There may be about 500 people trapped inside," he added.

More than 11,000 people have been rescued across Nepal, and power and communication lines have been restored in some areas, according to reports. However, survivors face immense challenges. "We did not have the time to grab anything before fleeing," one survivor from the badly hit Rasuwa district told Reuters. "What we were wearing is the only pair of clothes we have. And even they are wet from rain."

Rising death toll and international response

Nepal reported 1,050 bodies had been recovered by Tuesday, while China's state media reported 16 dead, bringing the overall death toll to 1,066, with a combined 4,462 people missing. At least 11,814 people have been rescued so far.

In a sign of the growing humanitarian crisis, China will send DNA testing experts and another shipment of relief supplies, and South Korea is deploying a 44-member emergency relief team, according to the ABC. More than US$42 million (A$59 million) in aid has flowed into Nepal.

Personal pleas and ongoing search

Among those anxiously awaiting news is Anamika Shrestha, a Victorian resident whose 65-year-old father, Ganesh Mani Shrestha, was working on a construction site at the Rasuwagadhi Integrated Customs Checkpoint on the Nepal-Tibet border. Ms. Shrestha expressed frustration that it took rescue teams about six days to reach the area where her father had been, and has called for more international help.

"We need specialised missing person search teams and then forensic and DNA support, and proper identification of anyone who has been recovered," she said. Her brother in Nepal has submitted DNA to authorities. "If we don't get the body … it's going to be really difficult for us thinking that maybe his soul is still not resting in peace," she added.

Rescuers are focusing on hydropower plant projects where hundreds of workers are believed to have been trapped, with images released by Nepal's army showing teams working through debris-filled tunnels to find signs of life. Excavators are working to move debris in the search for those trapped in Tibet, and rescue teams have used search dogs to scour rubble at the Gyirong Port border crossing.
