Uluru in central Australia |
The region that I will be looking at covers the island continent of Australia itself, the nearby large island of Tasmania, and the Torres Strait Islands between northern Australia and New Guinea. While nowadays New Zealand and Australia are often looked at together, at this point in history New Zealand was uninhabited. The Maori settlers would not arrive until later, so we will omit New Zealand from this blog.

The Aboriginal community today is still facing discrimination and major social problems caused by their disadvantageous position in Australian society. To sum up, there is a justified distrust of outsiders, including archaeologists, within the Aboriginal community and this has led to less archaeological work than may otherwise have taken place. The archaeological community and the Aboriginal people will have to work together to lay down guidelines and best practices to allow the study of history to continue in a way that does not do further harm to the community.
Australia had no records prior to the arrival of the Europeans. It does not seem to have even been written about (there may be some exceptions in later Indonesian text). This makes the period that we are looking at technically “before history” or pre-history. The extraordinary oral traditions of the Aboriginal peoples allow us to make some use of oral history, but this is not easy to do. The primary sources of the information in this blog is from archaeology with a smattering of historical linguistics and genetics thrown in.
According to the best guess by archaeologists Australia was inhabited perhaps 50,000-60,000 years ago. The lowest date on the current level of knowledge would be 40,000 years, as remains from Lake Mungo have been dated to this time. Human remains have been found, showing deliberate burial and with red ochre being used to decorate the dead. As an aside, I find it interesting that red ochre would be used at so many different times and places to decorate the dead. The Yamna culture from the Pontic steppe used red ochre, as did the Chinchorro peoples of the Andes and here we see the early Aboriginal cultures using this. It probably is just convergent cultural evolution, but it is interesting to see.
The Aboriginal peoples seem to have gained some unique genetic traits which seem to allow a greater than average tolerance to extremes of cold and heat. This is useful in Australia, which is a country of extremes. This would also affect archaeology however, as a culture whose inhabitants could survive great extremes of cold and heat might have less need to build shelters and thus would show up less in the archaeological record.
Torres Strait Islands |
After the horrendous 2004 earthquake and subsequent tsunami in the Indian Ocean, some scholars speculated that coastal peoples could have been swept up what are now the islands of Indonesia and dropped on the coast of Australia. It has to be admitted that this is theoretically possible and it would allow reaching Australia at a very early date without the use of boats or land bridges but one would have to assume that only a very few would be swept over and this would lead to an extreme genetic bottleneck (as the Aboriginal communities would be primarily descended from just a handful of individuals). This does not appear to be the case so, to my knowledge, tsunami diffusion remains no more than an interesting speculation.
Reconstruction of a Diprotodon |
When the humans first arrived the creatures of Australia may not have paid them any heed. Humans are relatively small compared to creatures such as the Diprotodon and may not have been considered a threat. However, humans would have quickly made their presence known and the large marsupials of Australia would have had to adapt to this new threat. About 45,000 years ago the largest creatures of the Australian megafauna seem to have gone extinct. It is not clear that humans are directly responsible, but it seems likely that they played a part. Humans would change environments to suit themselves, would have competed for resources and would occasionally have killed large creatures when they could. When an ice-age or dry period would arrive this competition from humans could become deadly to other animals and the most likely scenario is that the large creatures went extinct because of the presence of humans, although not necessarily because humans hunted them to extinction.
There is the possibility that an Aboriginal legend about a water spirit called a bunyip, which inhabited the waters of the Murray River, and would catch and kill humans that went down to the water, is an oral tradition remembering the Diprotodon, which like hippos, may have been deadly to humans without being explicitly carnivorous. If this is the case then either the dates for the extinction of the Diprotodon are in error, with some surviving in refuges, or the Australian oral tradition is the most enduring in the world, as no other culture to my knowledge has a folk memory that would endure for over forty-thousand years. But more work is needed. It is quite possible that the bunyip and the Diprotodon have nothing whatsoever to do with each other.
As the prehistoric peoples of Australia spread out throughout the continent they inhabited what is now the southern island of Tasmania, which would then have been connected to the mainland. If the seas were much lower at various stages, many crucial Aboriginal sites may now be under water, as humans seem to have often spread along the coastal regions.

Around 20,000 years ago, the last Glacial Maximum began. This may not have directly affected Australia but it would have made the climate far more arid and dry. This destruction of hunting grounds would have forced the inhabitants to flee to small areas that still had regular supplies of water and game. These are known as Ice Age refugia, with an example being the Lawn Hill Gorge site in present-day Queensland.
When the glaciers receded and the seas rose again, Tasmania was cut off for the last time from Australia, probably around 10,000BC. This would have also cut Australia off from the north, with the Torres Strait land bridge now simply existing as a chain of low islands between the lands of New Guinea and Australia.
Around this time the first securely attested boomerang was found, in Wyrie Swamp in southern Australia. While we sometimes think of the boomerang as a uniquely Australian tool it must be remembered that boomerangs were also used outside Australia and that not all Aboriginal peoples used boomerangs.
Around 9,000BC a stone alignment was made at Wurdi Youang in what is now Victoria. It is sometimes described as a circle but I find it more closely resembles a tear drop formation. It may possibly have been used as an astronomical tool, which is extremely interesting, as this would be one of the earliest astronomical observatories in the world if this is the case.

Linguistic Map of Australia The yellow regions show Pama-Nyungan languages |
Around 3000BC the Proto-Pama-Nyungan language would have been spoken. This is the language family that covers by far the most territory in Australia. Linguistically the northern coast of Australia has many different language families, while the entire southern region now speaks Pama-Nyungan languages (Pama-Nyungan would be analogous to Indo-European). It is unclear where Proto-Pama-Nyungan was first spoken and how it came to dominate the lands, but I suspect that the Pama-Nyungan speakers had found some way of adapting to the increased aridity of the land. This would have allowed them to expand their territory in regions that others may have found uninhabitable. The increased ability to survive may have seen other groups adopt the cultural practices of the Pama-Nyungan speakers, including their languages. This is speculation on my part however. The mechanism of expansion of this language is not fully understood.

Around 2000BC the rains seem to have returned to a more normal pattern. The end of the dry period would have allowed the land to bear more plants, support more wildlife and thus support more people. The Bradshaw rock paintings in north-western Australia seem to have stopped being produced around this time and a different style, the Wandjina style of paintings, were used in its stead.

There are theories that the dingo is related to the Pariah dog in India and that there were Indian sailors who reached Australia. This is possible, as the Indus Valley Civilisation was flourishing at this time and was trading with Mesopotamia and the Persian Gulf. But it is more likely that the dingo is related to the Singing Dog of New Guinea rather than the Pariah dog. Further research is needed but regardless, around this time dingoes appear in Australia. Dingoes were primarily wild, but some Aboriginal tribes domesticated them to some extent. This was the only domesticated animal on the Australian continent and the arrival of the dingo threatened the thylacine, which now had competition for that ecological niche.
Dingo |
There is not much more that I can say about the period. Around two millennia ago, (circa 1BC) the thylacine went extinct in Australia, probably due to competition from the dingo, but survived in Tasmania, which did not have dingoes. I am sure that there is much, much more that can and should be said about Australian history but I do not know enough to confidently say more so I will leave the account here. Hopefully this gives at least an introduction to the history of the Australian continent and gives context to what general trends were happening here when we are discussing the rest of the world.
