Matthew Eakin, who grew up in Cumnock but lived in Sydney, and Canadian Richard Cartier went missing last week on the mountain's Camp 1 (6000 metres) and Camp 2 (6700 metres) in separate incidents.

"Bodies of the climbers have been traced at a height of around 6500 metres," a spokesman for Alpine Club Pakistan told the DPA news agency on Wednesday.

A Department of Foreign Affairs and Trade official says Mr Eakin, who is in his 40s, died on Thursday last week and officials are providing consular assistance and condolences to his family and friends.

Former president of Orange Daybreak Rotary Bruce Smith said members would support Ms Brell, who was also active within the district, anyway they could.

"We are thinking of her," Mr Smith said.

For the past 12 years Ms Brell has regularly visited Nepal, and in 2018 was awarded the Order of Australia for her volunteer efforts.

Ms Brell, who is overseas, is also heavily involved in the Central West Women's forum and fellow member Gerraldine Colless said her friend was proud of her son, adding he recently donated a kidney.

"When we talked about Matthew, he was an adventurer, he was always doing something outlandish, he was an achiever as an adventurer," Ms Colless said explaining the pair shared a bond through the adventurous lifestyles of their sons.

"He lived life to the fullest and gave someone else the opportunity to do that too. She would be so proud of him."
