The first people arrived in Australia around 60,000 years ago when lower sea levels connected Australia, New Guinea, and Tasmania into one landmass called Sahul. As the last ice age ended around 10,000 years ago, rising seas separated the three areas. The first inhabitants of Australia were the Australian Aborigines, who lived in small hunter-gatherer groups and developed over 200 languages. Their way of life depended on the environment, with coastal groups trading goods and maintaining cultural connections with inland groups.
