Port Macquarie's Sam Blundell, 27, and 62-year-old Paul Rollo, were on a group trek led by Sam's father and Peak Potential Adventures managing director Shane Popher.

Peak Potential Adventures joint owner Darren Wise said the 13 people on the trek, including the expedition leader, were safe and well.

Sam's mother Fay Calvert said it was a frightening time before she knew her son was safe.

"I will just feel better when I see him again and hear his voice," Ms Calvert said.

Paul's fiancé Bronywn Boyd said on Sunday her tears had stopped and she looked forward to speaking with Paul.

"I am relieved they are OK but it is still a long haul to get them out of there," she said.

The group was on an Everest base camp trek to commemorate Anzac Day.

They are making their way to the town of Lukla from where they will fly to Kathmandu and then home.

Peak Potential Adventures continues to keep family and friends of trekkers updated.
