Most scientists think that people first arrived in Australia about 65,000 years ago.

When they came everything was very different to the way it is today.

The sea level was much lower. This means there was more land and the distances between islands were shorter.

Mainland Southeast Asia to the north-west of Australia was a much bigger land.

Scientists have called that old land Sunda. Also, Australia, Tasmania and Papua New Guinea were one big country back then. Scientists have called this old country Sahul.

This map shows the routes that might have been taken by the first people who came to Australia. Scientists still disagree about which of these routes is most likely. The red route going through Sulawesi is favoured by most scientists.

Generation after generation those ancestors travelled from north-west Sunda to Sahul crossing the ocean from island to island many times. Scientists think the largest strait at the time was around 70km. They were clever sailors and must have had good vessels to make the journey.

Some stayed on those islands, while others travelled all the way to Sahul. From what is now Papua New Guinea to Australia people could walk all the way. At that time those countries were not separated by the sea.

Scientists now think that probably thousands of people travelled this way over many years.
