Rescue teams said there are now no trekkers left stranded, almost one week after the avalanche that killed 40 people.
Around 500 people have been rescued, but the whereabouts of many Australians trekking in the Himalayas is unclear.
The Department of Foreign Affairs said there were no reports of Australian casualties, but approximately 40 people were unaccounted for.
Sydney man Simon Wilde and his 17-year-old daughter Sophie are among those missing.
Simon’s father Patrick said he remained hopeful for the pair, who were hiking through an area where nine people were killed.
“My wife and I have the hope and belief they are not in the area where the avalanches were,” he said.
Mr Wilde said he hopes the region's limited phone reception is the reason they haven't been in contact.
Sue Badyari, the head of a tour agency which takes up to 700 Australians each year through the challenging Annapurna trekking route, said there were still poor areas for satellite communication.
“You need to go into these mountains really, really prepared and unfortunately for many independent trekkers, there possibly isn't enough care, or due diligence or research,” she said.
DFAT says they're working with local officials, trek organisers and families to confirm the whereabouts of missing Australians.
