European Colonists
It is not known how aboriginals ended up in Australia, as it is an island. It is assumed that they have been there for many thousands of years, migrating from Asia.
Aboriginals
It is believed to be 40 000 years.
20,000 years
Evidence suggests that Aborigines arrived in Australia approximately 40,000 years ago.
The Aboriginal people of Australia have maintained the balance of nature in that country for thousands of years.
Aborigines have been in Australia for anowhere between 5000 and 40000 years.
Aboriginals have been in Australia for 40 to 60 thousand years. There's no way of telling who was the first.
The Australian aborigines migrated from Africa around 70,000 years ago, and started living in Australia about 50,000 years ago.
It isn't exactly known when they first migrated to Australia, but the general consensus is that the modern Aboriginals (Aboriginals as we know them today) migrated to Australia around (15,000 - 20,000) years ago. There is a LOT of evidence of a far older culture living in Australia for at least 60,000 years but dissapeared around the time the Aboriginals migrated here. The older culture was prominent in the north west of the country where paintings of the ancient "Wandjina" are the only remnants left of the first inhabitants.
Aboriginals were once denied the right to vote or drink, they were denied fair wages, for many years they had to apply for permission to travel and for many years they were denied their own children, as they were removed and placed into group homes.
No they got to Australia on foot when it was still connected to Asia.
