A Newcastle man whose wife has been missing since the Nepal - Tibet floods says he has not given up hope she will be found alive.
Bhavin Patel says he will return to Tibet as soon as possible to keep searching for his wife, Reshma.
Reshma Patel had always dreamed of doing a two-week pilgrimage to the Mount Kailash Mansarovar region in the Himalayas.
Rather than taking a helicopter tour, she was determined to do the trip on foot "before getting too old".
A month on from the flash floods, more than 1,400 people have died and more than 5,500 people remain unaccounted-for, including Ms Patel and 33 other Australians.
Mr Patel is calling for more to be done, while refusing to give up on the possibility that his wife is alive.
Mr Patel said he had been receiving daily updates from the Australian government, but that had stopped.
In a statement, a Department of Foreign Affairs and Trade spokesperson said the Australian government held grave concerns for the 34 Australians still missing.
The day after the disaster, Mr Patel travelled to Nepal to look for Ms Patel and the Isha Foundation tour group she was with.
At this stage, neither Nepal nor China has confirmed that any Australians are among the dead.
Last week at the UN General Assembly in New York, Nepal Prime Minister Balendra Shah called for urgent funds to help his country rebuild following the crisis.
