Emu War, military operation to address the issue of emus, large flightless birds, damaging large amounts of crops in Western Australia. The campaign lasted from November to December 1932. Three members of the Royal Australian Artillery were assigned to cull roughly 20,000 emus using machine guns. The assignment was made in response to petitions from local farmers complaining of emus destroying their crops. After two months, fewer than 1,000 emus were reported killed. The failure was the subject of national and international ridicule.
Emus have been common in Australia for thousands of years. Three subspecies are recognized, inhabiting northern, southeastern, and southwestern Australia; a fourth, now extinct, lived on Tasmania. Emus frequently migrate hundreds of kilometers over the course of a year in search of food and water. In 1922 the Australian government changed emus’ status from that of a protected native species to “vermin” in response to their destruction of large amounts of vital crops, such as wheat. Emus frequently broke through farmers’ fences, creating holes that then allowed pests such as rabbits to do more damage. Furthermore, when emus ate crops, they trampled anything growing nearby, causing even more damage to plants. In 1932 an unusually large migration, caused by drought, led to massive damage to wheat crops in Western Australia, particularly in the Campion district.
Farming in the Campion district was dominated by World War I veterans who had been settled on the marginal land there as part of a government program. These inexperienced farmers had struggled from the beginning, and by the time of the Emu War one quarter had already abandoned their land. The large-scale emu migration threatened to do serious economic harm to the region in the midst of the worldwide Great Depression. While farmers were permitted to shoot the emus themselves, their resources were limited, leading them to request government assistance. Minister for Defence George Pearce believed that dispatching professional soldiers to help the farmers would demonstrate that the government took veterans’ concerns seriously.
In November 1932 three members of the Royal Australian Artillery traveled to the Campion district: Maj. Gwynydd Purves Wynne-Aubrey Meredith in command, Sgt. S. McMurray, and Gunner J. O’Halloran. The group had two Lewis automatic machine guns and 10,000 rounds of ammunition. They were accompanied by a cinematographer.
On November 2 the three team members employed formation tactics against a group of roughly 50 emus. When the soldiers opened fire, the birds scattered in all directions, making them extremely difficult targets. On November 4 the soldiers laid an ambush for the emus at a water source. The gunners waited to open fire until thousands of emus were in range. However, one of the guns jammed after just a few rounds, and the emus quickly scattered.
After three days of the operation, only about 30 emus had been killed. Farmers attempted to herd the emus using trucks, but this proved ineffective; one truck even crashed after hitting an emu. A gunner tried shooting from a truck, but the emus were faster than trucks on the rough terrain, and the machine guns were difficult to aim. This highlighted a further problem: emus have tough hides, and thus a glancing bullet from a machine gun rarely led to death or severe injury. It was also difficult to judge the immediate effectiveness of an attack, as some emus kept running after being shot and only later died of their injuries.
By November 8 news reports had widely publicized the failure of the “Emu War.” Members of the Australian House of Representatives made light of the situation, joking that if anyone deserved medals from the conflict, it was the emus, who had “won every round so far.” Meredith and his team withdrew on November 8, but local farmers demanded their return. A report that 300 emus had been killed justified Pearce’s decision to redeploy the machine gunners on November 12.
Meredith later reported that 986 emus were killed between November 12 and December 10, with an additional 2,500 later dying of their injuries. These numbers have been disputed, but, even if they are accurate, the ratio of bullets expended to casualties was considered too high to justify continuing.
It soon became clear that one emu in each group served as a lookout to warn the others, giving them time to escape. Meredith stated publicly that the emus could “face machine guns with the invulnerability of tanks.” Such statements made military action against the emus increasingly unpopular, with opponents arguing that such treatment of emus was inhumane.
Ultimately, the emus were considered the “victors” of the war. By 1934 the government had begun to supply farmers with ammunition and had created bounties for emu hunting. Roughly 57,000 bounties for dead emus were claimed in six months. The only permanent defense against emus proved to be the expansion of fencing over long distances. However, this was controversial, and authorities were accused of endangering the survival of the emu as a species by preventing them from completing their migrations. Australian wild emus became formally protected by the Environment Protection and Biodiversity Conservation Act in 1999.
