How a flightless bird army defeated the Australian military in 1932

In short: In 1932, the Australian government declared war on emus to protect vital wheat crops. Armed with machine guns, three soldiers from the Royal Australian Artillery set out to cull the massive birds. Instead of a decisive victory, they faced an unexpected adversary that proved nearly impossible to stop.

The conflict arose from a perfect storm of environmental and economic pressures. Following World War I, the Australian government established a soldier settlement scheme, providing roughly 5,030 ex-soldiers with plots of land to farm wheat and sheep. By 1922, the government had purchased 90,000 hectares for these veterans, many of whom were settled on marginal land near Perth. When the Great Depression hit in 1929, wheat prices plummeted, and a severe drought triggered a massive migration of emus toward these struggling farms.

The emus, which can stand over 5 feet tall and weigh more than 45 kg, were not just eating the crops; they were trampling them and breaking fences, which allowed rabbits to enter and cause further damage. In response to the destruction, the government reclassified the emus from protected species to 'vermin.' When the veterans' attempts to hunt the birds failed, they requested military assistance. Three members of the Royal Australian Artillery were deployed with machine guns to tackle a population of roughly 20,000 emus.

The military campaign, which ran from November 12 to December 10, 1932, was a tactical failure. Despite the firepower, the emus proved incredibly resilient; one observer famously noted that if the birds had military-grade bullet capacity, they could face any army in the world. Reports vary on the casualties, but it is estimated that fewer than 1,000 emus were killed during the two-month operation, though some accounts suggest an additional 2,500 died later from injuries. The failed mission became a source of international ridicule, and the government eventually pivoted to providing ammunition and bounties for hunters instead.
