Other researchers have mapped massacre events in Australia in which more than six people were killed. Not all frontier conflict resulted in the deaths of large numbers of people, however. Large massacres were typically preceded by a series of smaller events and followed by others afterwards. These often included attacks on livestock or property rather than people, or the killings of individual people on both sides.

Our aim was to reconstruct as comprehensively as possible the scale and nature of all frontier conflict events, including violence that took place before the Native Mounted Police were officially established. All of this conflict would have set the scene for Indigenous people in their subsequent interactions with settler-colonists.

We divided conflict into four categories: attacks on stock or property, attacks on non-Indigenous people, attacks on Indigenous people and attacks on the Native Mounted Police themselves.

All together, we mapped more than 2,500 of these conflict events across colonial Queensland from 1623 until 1911. Our findings show violence occurred everywhere, but was especially common along the east coast and on Cape York Peninsula.

Violence commenced in Queensland in 1623, with the voyage of the Dutch vessel Pera, captained by Janszoon Carstensz. After settler colonists arrived in the early 1800s, we found violent incidents taking place in every decade from the 1820s onwards, peaking in 1866.

Because historical documents are biased in their focus on violence towards settlers, the most common form of conflict recorded was the killing of livestock, such as sheep, cattle and horses.

Pastoralists, agriculturalists, farmers and selectors had often invested their life savings in buying livestock and taking up land. They could little afford to lose their animals to Aboriginal spears. When they did, they often called in the Native Mounted Police, whose presence began a series of retaliatory events.

Potentially higher death rates from conflict

Of the 165 Native Mount Police camps we have identified in our research, 150 have relatively secure beginning and end dates, with an average duration of 13 years per camp. This suggests that, generally, it took just over a decade to curb Aboriginal resistance in any given region.

In some areas, though, it took much longer. In the Cook Pastoral District (which covers most of Cape York Peninsula), for example, a staggering 54 Native Mounted Police camps operated from 1868 until 1929.

When the areal extent of different historic pastoral districts is taken into account, however, some had an even greater density of Native Mounted Police camps than Cook. Even though the Wide Bay District in southeast Queensland had only six camps between 1850 and 1864, its small size meant the Native Mounted Police presence here was quite intense.

Our data also suggests the death rates of frontier Aboriginal peoples was considerably higher than previous estimates.

Historians Raymond Evans and Robert Ørsted-Jensen have estimated some 41,000 Aboriginal people could have been killed at the hands of the Native Mounted Police between 1859 and 1897. Their estimate was based on reasonable and minimal assumptions drawn from historical documents and an average seven-year lifespan per camp.

Extending the duration of a camp to 13 years, in line with our newly identified data, increases the total deaths to potentially over 60,000.

Ripples in Australia today

The government policies that allowed this decimation of Indigenous lives continue to have very real implications in Australian society today.

Australia’s colonial history has been built on policies designed to secure and maintain possession of Indigenous lands. Historically, colonial powers employed forces like the Native Mounted Police to enact widespread violence on the Indigenous people who stood in the way of this.

We can see the repercussions of historical actions to displace Aboriginal communities in processes such as native title claims. These processes force Aboriginal people to prove generational connections to land from which they were, at best, marginalised, and at worst, excluded.

Many Aboriginal groups can trace their families back to only a handful of ancestors because so many people were killed outright, died from starvation and disease, or were removed through measures such as the Stolen Generations.

The resounding defeat of the recent Voice to Parliament referendum is another case in point. It reveals a lack of understanding of the historical nature of violence against Indigenous people, the racist foundations of settler Australia, and how these continue to impact communities today.
