THE latest Australians to conquer Mount Everest reached the top of the world despite two of the three-man team having to overcome pneumonia early in the expedition.
The success by climbers David Chiew, a Sydney doctor, Robert Jackson, from the NSW Hunter Valley, and Mark Sheen, from Perth, brought the unofficial tally of Everest climbs this season to almost 470.
Today's climb also put Jackson in the elite group of climbers to have conquered the seven summits, the highest peaks on each of the world's seven continents.
Various Everest and mountaineering websites said there also had been six deaths on the world's highest mountain this year.
Chiew, Jackson and Sheen began their final summit push early today and reached the peak just after daybreak. With them was Sherpa Sirdir Namgia who reached the summit today for the second time this year.
