In order to encourage men to serve, land grants of were provided for soldiers who completed five years. Nevertheless, the colony's military force grew only marginally; by 1876 there were 415 men under arms in the colony's service. These were distributed across two batteries of artillery in Brisbane and Ipswich, some Brisbane-based engineers and six companies of infantry in Brisbane, Ipswich, Warwick, Rockhampton and Toowoomba. In an effort to rectify the lack of manpower, Queensland passed the "Volunteer Act" in 1878. Within two years the size of the force had grown to 1,219 men. That same year, 1880, payments to volunteers for attending annual camps were stopped.
