Australia is a very flat continent where the average elevation is just 330 metres, the lowest in the world. What Australia lacks in height is more that made up for in the variety, geological age and unique appearance of its mountains and rocky outcrops - some of the oldest and most interesting exposed rocks in the world. The highest point in Australia is Mount Kosciuszko (named by Sir Paul Edmund de Strzelecki in 1840 after the Polish patriot and democratic leader Tadeusz Kosciuszko) in New South Wales, at 2,228 metres above sea level. Mount Kosciuszko is part of the Great Dividing Range.
