Enemy On Their Tracks comprises a curated collection of primary source materials including official and personal letters, newspaper articles, and Native Police reports that follow the spread of British pastoral colonialism through Central Queensland from 1855 to 1870.

The evidence of bloody warfare, murder, and dispersal of First Nations Peoples collected here includes the touchstone event of the Cullin-la-Ringo massacre in 1861 which was the largest loss of European life in a single incident in the Australian Frontier Wars.

As horrific as this event was it pales in the light of the subsequent brutal reprisal murders of First Nations Peoples which historians estimate extinguished up to 370 lives.
