The Frontier Wars was a campaign by British settlers to drive Aboriginal peoples off their lands.
The British settlers arrived with the First Fleet in 1788. A penal colony was established at Port Jackson, which is now the site of the Sydney central buisiness district.
The penal colony gradually expanded outwards, and other colonies were established on Aboriginal lands across the region.
"Settlers" were granted land grants by the British. Initially, these land grants were limited, but after some time the British Crown ran a land grant system that effectively rewarded settlers in "clearing" the land - a euphamism for murdering or driving off Aboriginal people.
There were many, many massacres of Aboriginal people. The British Crown legally prosecuted the perpetrators of very few massacres, the most well known being the Myall Creek massacre.
A research team from The University of Newcastle has a project which is available online about the locations and details of the massacres.
