What is the name and height of the largest mountain in Australia?

Answer 1

The tallest mountain in Australia is Mt Kosciuszko, at 2228m (some sources say 2229m), or 7310 feet. It is situated in the Australian Alps, in southern New South Wales.

Whilst Australia's highest mainland mountain is Kosciuszko, Mawson Peak on the Australian external territory of Heard Island is higher, at 2745 m.

Although the mountain with the highest peak on mainland Australia is generally recognised to be Mt Kosciuszko, there is still some debate about whether explorer Paul de Strzelecki named the highest mountain Kosciuszko or whether Mt Townsend was the higher, as his instrumentation was not completely accurate. There is some slight evidence to suggest that the map-makers assigned the alternate names to the mountains, and that Mt Townsend should in fact be called Kosciuszko and vice versa.
