Edited sentence: Frontier collisions and punitive expeditions against indigenous people on Australia's frontier were thus generally veiled in secrecy due to fear of possible legal consequences, especially following the Myall Creek Massacre in 1838.However, we will never be able to locate or describe in detail more than a small percentage of these events.In cases where reports had to be written the records can at times be seen as having been later destroyed.It is generally acknowledged that the European as well as indigenous death toll in frontier conflicts and massacres in Queensland exceeded that of all other Australian colonies, yet it is certainly not possible to map out more than a small percentage of the numerous massacre sites in Queensland.Recent studies into the most significant and notorious case of this kind, that of Queensland and its Native Police Force, show that all Native Police reports and monthly enumerations of patrols originally stored in the Queensland Police Department went missing sometime after 1905 when the last station closed.The colonial Australian frontier war was unofficial, undeclared and unrecorded, and the official actions of government forces was  typically veiled as "policing" and "law-enforcement" although a police force normally is not constitutionally allowed to engage in acts of warfare.Thus any attempt to list all events of this kind will of nature (at least in Queensland), be more deceptive than revealing.We can calculate in various ways the minimum amount of frontier 'dispersals' performed by the Native Police Force (as was indeed done recently by Dr Raymond Evans and Robert Orsted-Jensen based on a small portion of monthly native police summaries of now lost 'collision reports' stored in the archives) the approximate amount dispersals performed by the native police during half a century
