text:  Central to the success of the Europeans was the use of firearms . However , the advantages afforded by firearms have often been overstated . Prior to the late 19th century , firearms were often cumbersome muzzle @-@ loading , smooth @-@ bore , single shot muskets with flint @-@ lock mechanisms . Such weapons produced a low rate of fire , while suffering from a high rate of failure and were only accurate within 50 metres ( 160 ft ) . These deficiencies may have initially given the Aborigines an advantage , allowing them to move in close and engage with spears or clubs . Yet 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 Aborigines , often proved successful . The Europeans also had to adapt their tactics to fight their fast @-@ moving , often hidden enemies . Tactics employed included night @-@ time surprise attacks , and positioning forces to drive the natives off cliffs or force them to retreat into rivers while attacking from both banks .
