Mountaineer Mick Parker will be farewelled at his funeral in Melbourne on Friday.
Mr Parker, 36, died in Nepal on Thursday, June 4, two weeks after scaling Makalu, the world's fifth-highest mountain, without the aid of oxygen.
His father Bruce Parker returned to Australia with his son's body on Tuesday.
Mr Parker suffered oedema - a build-up of fluid - on the brain and lungs, and blacked out several times as he returned to Kathmandu after the climb.
The graphic designer from Warrandyte, in Melbourne's east, had climbed five peaks over 8,000 metres and had attempted eight others, including Mount Everest, without sherpas or oxygen.
He had led Australian Army Alpine Association expeditions to some of the world's most dangerous peaks.
His father described Mick as "strong-willed and sensitive" and a dedicated climber who didn't receive due credit for his mountain-climbing accomplishments, including his efforts to save the life of a fellow mountaineer last year.
"He never, ever sought the recognition he deserved," Mr Parker said.
"He just loved climbing. He used to shun the limelight but ... he should be recognised even if it's after his life."
Mr Parker's funeral will be held at the Lilydale Memorial Park in Victoria Road, Lilydale, at 1pm (AEST) on Friday.
