What is the second highest mountain in Australia and what is its height in meters?

Answer 1

Australia's second highest mountain on the mainland is Mt Townsend, with an elevation of 2209m. It is located near Australia's highest mountain, Mt Kosciuszko, in the Australian Alps.

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.
