Analysis of pollen and charcoal giving a date of 120,000 BP suggests that people were using fire to clear land in the Lake George basin in the Southern Tablelands of NSW, about 30 kms north-east of Canberra.  Experts also found signs of human disturbance in rainforest pollen patterns in a drill core from the edge of the continental shelf, 80 kilometres east of Cairns.

Suggested age of two north Australian sites (Nauwalabila and Malakunanja, about 300 kms east of Darwin).
Archaeological evidence suggests that a rock shelter was used by people at a site in Arnhem Land (400 kms east of Darwin) in the Northern Territory. They used stone tools and red ochre probably to prepare pigments for rock painting or body decoration.
Archaeologists find the earliest known use of ochre in Australia and south-east Asia and bone fragments of extinct megafauna, including the diprotodon, at the Warratyi rock shelter in the northern Flinders Ranges, SA, in the traditional lands of the Adnyamathanha people. “The idea there was no interaction between humans and megafauna has really been put to bed by the Warratyi evidence.” 
Rock engravings made in South Australia - the earliest dated petroglyphs.
Age of ‘Mungo Man’ (also known as Lake Mungo 3 human remains, or LM3), a hunter gatherer who lived in western NSW. His skeleton is the oldest known remains in Australia. Named after Lake Mungo National Park, NSW, 987 km west of Sydney, where his remains were found. Footprints discovered at Lake Mungo are believed to be 23,000 years old.
The oldest dated art in Europe is 40,800 years old and was found in the El Castillo cave in Spain. It contains many red hand stencils, similar to stencils found in Australia.Lake Mungo, New South Wales. Ancient camp sites have been found in this area.

Aboriginal people living at Malangangarr in Arnhem Land, Northern Territory, use ground-edge grooved axes. Australian technology leads the world.
In deep caves under the Nullarbor Plains at Koonalda (at the western edge of South Australia, about 50 kms from the ocean), Aboriginal people mine flint and leave grooved designs on the cave walls. This is early evidence of the close relationship of art and work in Aboriginal life.Wentworth Falls, New South Wales. An occupation site has been found in this area dated 22,000 years old.
Aboriginal people were dispersed across the entire continent, occupying places as remote as rock shelters on the Franklin River in south-west Tasmania and at Birrigai in the ranges of the Australian Capital Territory, which surrounds Canberra, the national capital.
Some 10% of Tasmania is covered by glacial ice. Kutikina Cave on the Franklin River is occupied by Tasmanian Aboriginal people at the height of the last ice age.
Harvesting grass seeds is integral to Aboriginal socio-economic life on the large grasslands. The seeds were ground and baked or roasted and eaten whole.
Art at Ubirr in Kakadu National Park (Northern Territory, 300 kms east of Darwin) depicts now extinct animals, the Thylacine (Tasmanian tiger), and Zaglossus (the long-beaked echidna).
Hearths, stone and bone tools, Shaws Creek near Yarramundi (60 kms north-west from Sydney), NSW.
Sea levels begin to rise as ice caps melt. Inland lakes such as Lake Mungo have dried up.
Land bridges between mainland Australia and Tasmania are flooded. Tasmanian Aboriginal people become isolated for the next 12,000 - 13,000 years.
At Kow Swamp near Cohuna, 230 kms north of Melbourne, Victoria, Aboriginal people weare kangaroo teeth headbands similar to those worn by men and women in the Central Desert in the 19th century.

Aboriginal people at Wyrie Swamp near Millicent, 340 kms south-east of Adelaide, South Australia, use returning boomerangs to hunt waterfowl.

Earliest visible evidence of Aboriginal belief connected with the rainbow Serpent. This becomes the longest continuing belief in the world.

Research indicates that humans migrated to Australia from India , bringing with them different tool-making techniques such as microliths (small stone tools that formed the tips of weapons), and the Dingo, which most closely resembles Indian dogs.
