Some archaeologists have argued for an initial human migration into Australia through New Guinea. This is because islands across northern Indonesia are relatively close together, and people could easily see to the next island they wished to voyage to. First landfall on Australia has been argued to be both more difficult and less likelythan first landfall at New Guinea, as the final crossing distance from Timor to the continental shelf was more than 80km.
It was also thought that the Australian landmass was not visible from any Indonesian island. Despite this, it was proposed that now submerged islands off the Australian continental shelf were visible from Timor.
But until recently, computer technology and ocean floor data sets were not developed enough to know for sure. See full list on realclearscience. When people first migrated to Indonesia, reaching Australia by 60years ago, they found a landscape that looked very differentfrom today. During an ice age known as Marine Isotope Stage which stretched from roughly 70to 50years ago, western Indonesia formed part of the Pleistocene continent of Sunda, while Australia and New Guinea were joined to form Sahul. This event drowned the ancient continent of Sunda, creating many of Indonesia’s islands, and split the continent of Sahul into Australia and New Guinea.
This means that what is now under the ocean is very important to understanding where the First Australians might have made landfall. Our new researchuses computer analyses of visibility between islands and continents. We included landscape surface height data of regions of the ocean floor that were above sea level – and dry land – during the last ice age.
Running more than 10analyses allowed us to pinpoint where people could see to, from any location on any island or landmass in the whole of Island South East Asia. But because we knew that so many Indonesian islands, and so much of Sahul, were drowned at the end of the last ice age, we also included ocean floor (bathymetric) data in our analyses. We discovered that in the deep past (between 70to 60years ago, and potentially for much longer), people could see from the Indonesian islands of Timor and Rote to a now drowned island chain in the Timor Sea. From this island chain it was possible to sight the Australian continental shelf, which in the last ice age formed a massive fan of islands extending towards Indonesia. Much of this landscape is now more than 100m below the surface of the Timor Sea.
As the island chain sat at the midpoint between southern Indonesia and Australia, it could have acted as a stepping-stone for Australia’s first maritime explorers. Including the areas of the ocean floor that were dry land in the last ice age means we were able to show that people could see from one island to the next, allowing them to island-hop between visually identifiable landmasses all the way to northern Australia. If people island-hopped from Timor and Rote they would have arrived on the now submerged coastline close to all of Australia’s most ancient occupation sites, such as Madjedbebe, Nauwalabila and Boodie Cave. But while we might be closer to understanding where people first reached Australia, signs of the earliest explorers to reach Indonesia have been more elusive. Now, researchers have found evidence that suggests the ancestors of Aboriginal Australians landed.
This was the original colonization of Australia by homo sapiens. There are ancient genetic associations between New Guinean and native Australian populations as early as 40years back. Hence, this proves the theory that they walked. Humans moved from Southeast Asia onto this landmass, some settling in what is now New.
How did early humans arrived in Australia? Who were the original people of Australia? When did Aboriginal people first arrive in Australia?
This is supported by a date of 5000–60years ago for the oldest evidence of settlement in Australia , around 40years ago for the oldest human remains, the earliest humans artifacts which are at least 60years old and the extinction of the Australian megafauna by humans between 40and 10years ago argued by Tim Flannery. Archaeological evidence, from bones to rock art paintings, suggests that Australia. Conditions took a bit of a step backwards in the wake of WWII, as huge numbers of displaced people flocked to Australia for a fresh start. To meet deman troop ships were refitted to cram as many people aboard as possible.

There are two likely routes of entry, the northern-most through the Indonesia Moluccan archipelago to New Guinea, and the second a more southern route through the Flores chain to Timor and then to Northern Australia.

People have lived in Australia for over 60years. They lived in all parts of Australia. Aborigines invented tools like the boomerang and spear. Aboriginal artefacts on Rottnest Island have been dated from 5to more than 30years ago.
There is also evidence that the Aboriginal people. However, more recent evidence suggests human occupation by or even before 5000. Australia – Australia – People : Today the population of Australia consists of more than 2ethnic groups.
Until the mid-20th century, however, Australian society was, with some accuracy, regarded in the wider world as essentially British—or at any rate Anglo-Celtic. People in Australia and abroa including politicians and celebrities, have been eager to find ways to offer assistance and support. But authorities have warned that some kinds of help can.
