Mount Kosciuszko is the highest mountain in Australia (not including its external territories). It is located in the Snowy Mountains in Kosciuszko National Park. Mount Kosciuszko is not particularly difficult to climb. There is a road to Charlotte Pass, from which it's an 5 mile walk up a path to the summit. The peak may also be approached from Thredbo, which is a shorter 4 miles and supported by a chairlift year-round.
