Australia offers military flights to citizens trapped in Nepal

Australians stranded in Nepal following a deadly earthquake will be offered military flights out of the country.

Consular officials have contacted more than 1150 Australians in Nepal and Foreign Minister Julie Bishop saidthey are safe and well.

Melbourne woman Renu Fotedar died after an avalanche at the Mount Everest base camp on Sunday caused by a 6.7 magnitude aftershock.

Her family are in Kathmandu where they are receiving consular assistance.

"We will continue to search for any Australians who are unaccounted for," Ms Bishop said.

The family of missing Adelaide student Zachary Sheridan is confident he is safe, although he has not made contact since the quake hit Nepal.

However, his sister Zoe Sheridan says there has been reassuring news from the area where he is believed to have been staying.

Their brother, actor Hugh Sheridan, and another sibling are on their way to Nepal to look for Zachary.

The Department of Foreign Affairs will release details of the military flights when arrangements at Kathmandu airport have been finalised.

While the highly vulnerable will be given first priority, the federal government is encouraging Australians if they can to pursue commercial flights out of the country.

Australia is adding $1 million to its immediate aid to Nepal, bringing its total contribution to $6 million.

The additional funds are coming out of Australia's package of assistance to the World Health Organisation.

As well, Australia has a search and rescue team available for deployment to Nepal where it could join 10 other teams from around the world.

Ms Bishop said the team was waiting for approval from Nepal before it moved in.

"We, of course, stand ready to assist," she said, adding Australia was working with the US and Japan to coordinate efforts.

Meanwhile, the opposition has called for Australia to chip in more money.

Labor's foreign affairs spokeswoman Tanya Plibersek said the initial amount allocated for humanitarian assistance was "pretty modest".
