Australian trekkers still missing in Nepal

Loved ones are desperately waiting for news of missing Australian trekkers in Nepal after a deadly snowstorm in the Himalayas.

The Department of Foreign Affairs and Trade says it has been in close contact with Nepalese officials since Tuesday's avalanches in which at least 29 people are reported to have died.

Concerned family and friends of trekkers should try contacting those missing directly multiple times because reception in the remote Mustang and Manang districts near Annapurna is unreliable, a DFAT spokesman said.

Australian Bazil Plumb had been waiting anxiously for days to hear from girlfriend Nicole Wise.

On Friday, he learnt she was airlifted to safety out of the mountains - she had been trapped in an avalanche with her guide.

"Was so hard to stay positive from the other side of the world," he posted on Facebook as the happy news broke.

"Everyone who cared definitely helped me a lot.

"Stoked!"

For other loved ones, the wait is still on, with more than 100 trekkers from around the world yet to be found.

"Embassy staff remain ready to assist any Australians affected by this tragedy," a DFAT spokesman said.

"Nepalese authorities continue to advise there are no reports of Australian casualties, so far."

The spokesman didn't say how many Australians were believed missing.
