Era 1: Colonisation

The colonisation of Australia had a devastating impact on the Indigenous people who had lived on this land for over 60,000 years. 


Prior to British settlement, more than 500 Indigenous nations inhabited the Australian continent, approximately 750,000 people in total. (1). Their cultures had developed over 60,000 years, making Indigenous Australians the custodians of the world’s most ancient living culture. Each group lived in close relationship with the land and had custody over their own traditional country.

In 1770, during his first Pacific voyage, Lieutenant James Cook claimed possession of the east coast of Australia for the British Crown. Upon his return to Britain, Cook’s reports inspired the establishment of a penal colony in the newly claimed territory. The new settlement was designed to alleviate overcrowding in British prisons, expand the Empire, assert Britain’s claim to the territory against other colonial powers, and establish a British base in the global South. 


In 1788, two years after the decision to colonise Australia was made, Captain Arthur Phillip and 1,500 convicts, crew, marines and civilians arrived at Sydney Cove.

It is estimated that between 1788 and 1900, the Indigenous population of Australia was reduced by 90%. (2)


Three main reasons for this dramatic population decline were:

  1. The introduction of new diseases
  2. Settler acquisition of Indigenous lands
  3. Direct and violent conflict with the colonisers


The most immediate consequence of colonisation was a wave of epidemic diseases including smallpox, measles and influenza, which spread ahead of the settlement frontier and annihilated many Indigenous communities. Governor Phillip reported that smallpox had killed half of the Indigenous people in the Sydney region within fourteen months of the arrival of the First Fleet. (3). The sexual abuse and exploitation of Indigenous girls and women also introduced venereal disease to Indigenous people in epidemic proportions. (4)

The Government is fast disposing of the land occupied by the natives from time immemorial. In addition to which settlers under the sanction of government may establish themselves in any part of this extensive territory and since the introduction of the numerous flocks and herds. . . a serious loss has been sustained by the natives without an equivalent being rendered. Their territory is not only invaded, but their game is driven back, their marnong and other valuable roots are eaten by the white man's sheep and their deprivation, abuse and miseries are daily increasing.”
Francis Tuckfield, Wesleyan Missionary, 1837 (5)

Moreover, the expansion of British settlements, including the establishment of colonies in Van Diemen’s Land (Tasmania), Adelaide, Moreton Bay (Brisbane) and Port Phillip (Melbourne), resulted in competition over land and resources, and quickly lead to violence.


Levels of frontier violence are hotly debated (see Reynolds and Windshuttle), but historical records do document numerous occasions on which Indigenous people were hunted and brutally murdered (see Massacres Map). Massacres of Indigenous people often took the form of mass shootings or driving groups of people off cliffs. There are also numerous accounts of colonists offering Indigenous people food laced with arsenic and other poisons. (6)

Fight between Aboriginies and mounted whites.

"In less than twenty years we have nearly swept them off the face of the earth. We have shot them down like dogs. In the guise of friendship we have issued corrosive sublimate in their damper and consigned whole tribes to the agonies of an excruciating death. We have made them drunkards, and infected them with diseases which have rotted the bones of their adults, and made such few children as are born amongst them a sorrow and a torture from the very instant of their birth. We have made them outcasts on their own land, and are rapidly consigning them to entire annihilation."

~Edward Wilson, Argus, 17th March 1856 (7)


It is important to recognise that throughout the colonisation process, Indigenous Australians continually resisted the infringement of their rights to their lands, and its impact on their cultures and communities. 


It is estimated that at least 20,000 Aboriginal people were killed as a direct result of colonial violence during this era of shared Australian history. Between 2,000- 2,500 settler deaths resulted from frontier conflict during the same period. (8)

Stop & Think... How important is your way of life?

  • Imagine how you would feel if you welcomed strangers into your home and they never left. In fact, what would it be like if they took control of your house and made you relocate far away? What if they abused you physically, sexually and financially, and spread disease throughout your community? Can you imagine how this would affect your children and grandchildren’s view of these strangers for generations to come?
  • Consider what it would be like to see a previously unknown disease, with a 50% fatality rate, sweep through your community, affecting your family and friends.
  • How would it make you feel to know that so much of your culture had been permanently lost, with no way to fully rediscover it in all it’s richness?

The reality of the first collision of cultures between Indigenous Australians and British colonials has gone unacknowledged for most of our shared history. Many Indigenous Australians have wrestled with defining their identity when so much of their traditional culture has been lost, and at the same time their relationship with majority Australian culture is complicated by its role in their own loss of tradition.
