One of my homework tasks at school was to compile a list of the ten tallest mountains in Australia. I think most of my class got out an atlas to look for the ones on the mainland and Tasmania. I, due to being bored and deciding to look up the Heard and McDonald Islands, which are two uninhabited islands in the middle of the Indian Ocean that are Australian territories, found out that they have the only two volcanoes in Australia. One of the two volcanoes was one of the tallest mountains in our territory, according to Wikipedia.
So I decided to continue studying it, and found out that it had last erupted in 1993. There wasn't really anything else to see, so I continued to compile a list of the top ten tallest mountains in Australia.
Mawson Peak was Number 2. Mount McClintock, which is found in Australian Antarctic Territory, was Number 1.
