Despite an undeserved reputation of colonial inferiority, many of the locally raised units were highly organised, disciplined, professional, and well trained. For most of the time from settlement until Federation, military defences in Australia revolved around static defence by combined infantry and artillery, based on garrisoned coastal forts; however, in the 1890s improved railway communications between all of the eastern mainland colonies (Queensland, New South Wales, Victoria, and South Australia), led Major General Bevan Edwards, who had recently completed a survey of colonial military forces, to state his belief that the colonies could be defended by the rapid mobilisation of standard brigades. He called for a restructure of colonial defences, and defensive agreements to be made between the colonies. He also called for professional units to replace all of the volunteer forces.
