It may be inaccurate, however, to depict the conflict as one sided and mainly perpetrated by Europeans on Indigenous Australians. Although many more died than Europeans, some cases of mass killing were not massacres but military defeats, and this may have had more to do with the technological and logistic advantages enjoyed by Europeans.[23] Indigenous tactics varied, but were mainly based on pre-existing hunting and fighting practices—utilising spears, clubs and other primitive weapons. Unlike the indigenous peoples of New Zealand and North America, on the main they failed to adapt to meet the challenge of the Europeans, and although there were some instances of individuals and groups acquiring and using firearms, this was not widespread.[24] In reality the Indigenous peoples were never a serious military threat, regardless of how much the settlers may have feared them.[25] On occasions large groups attacked Europeans in open terrain and a conventional battle ensued, during which the Aborigines would attempt to use superior numbers to their advantage. This could sometimes be effective, with reports of them advancing in crescent formation in an attempt to outflank and surround their opponents, waiting out the first volley of shots and then hurling their spears whilst the settlers reloaded. Usually however such open warfare proved more costly for the Indigenous Australians than the Europeans.[26]
Central to the success of the Europeans was the use of firearms, however the advantages this afforded have often been overstated. Prior to the 19th century, firearms were often cumbersome muzzle-loading, smooth-bore, single shot weapons with flint-lock mechanisms. Such weapons produced a low rate of fire, whilst suffering from a high rate of failure and were only accurate within 50 metres (160 ft). These deficiencies may have given the Aborigines some advantages, allowing them to move in close and engage with spears or war clubs. However by 1850 significant advances in firearms gave the Europeans a distinct advantage, with the six-shot Colt revolver, the Snider single shot breech-loading rifle and later the Martini-Henry rifle as well as rapid-fire rifles such as the Winchester rifle, becoming available. These weapons, when used on open ground and combined with the superior mobility provided by horses to surround and engage groups of Indigenous Australians, often proved successful. The Europeans also had to adapt their tactics to fight their fast-moving, often hidden enemies. Strategies employed included night-time surprise attacks, and positioning forces to drive the Aborigines off cliffs or force them to retreat into rivers while attacking from both banks.[27]
