In Australasia, the continent's Second Summit on the Bass list, Mount Townsend, is more challenging than Mount Kosciuszko, but still just a walk-up. The normal route on the highest peak of the Messner list, Carstensz Pyramid, is technically difficult (UIAA grade V+). Puncak Mandala, however, is extremely challenging with respect to the approach route, which is arguably the more significant problem in climbing the New Guinea peaks. There have been perhaps only two successful approaches (and climbs) reported.
