History

The Great Emu War

Australia declared war on emus in 1932. The emus won.

Why this rabbit hole matters

In 1932, the Australian government deployed soldiers armed with Lewis guns to the Campion district of Western Australia to cull emus that were destroying wheat crops. The operation was a military and public relations catastrophe. The emus proved remarkably difficult to kill, survived sustained machine gun fire, and scattered into smaller groups that were impossible to herd. After weeks of effort and international mockery, the military withdrew. Ornithologist Dominic Serventy remarked that the emus 'could face machine guns with the invulnerability of tanks.'

The Great Emu War of 1932 began when around 20,000 emus migrated to the Campion district of Western Australia, destroying wheat crops grown by WWI veterans who had been given land as part of a soldier-settlement scheme. Desperate farmers petitioned the government. The military response — Major G.P.W. Meredith commanding two soldiers with Lewis guns and 10,000 rounds of ammunition — became a farce. Emus scattered at the sound of guns, survived hits that would stop humans, and the campaign became a national embarrassment that was reported internationally. The emus suffered casualties; wheat crops continued to fail.

Wildlife Management

Wildlife management involves regulating animal populations and habitats to balance ecological health, agricultural needs, and human safety. Methods range from hunting and culling to fertility control, habitat management, and relocation. Culling is controversial — it is often ineffective (target species recover quickly) and generates public opposition. The emu problem in 1932 was genuine: 20,000 emus can destroy thousands of hectares of crops. Modern wildlife management in Australia includes aerial culling, exclusion fencing, and integrated pest management programs.

Military Failures

Military history is littered with operations that failed due to underestimating the enemy, poor planning, or applying the wrong tools to the problem. The Emu War sits in a category of military embarrassments where the 'enemy' was not another army. Other examples include the US military's various failed attempts at non-human 'weapons' — bat bombs (WWII), anti-tank dogs (USSR), and dolphin mines (various). The emu campaign's failure was predictable: Lewis guns designed for human targets were not optimized for dispersed, fast-moving birds with distributed vital organs.

Conservation Debates

The emu has gone from agricultural pest to protected species in parts of Australia. More broadly, animals that were routinely culled or eradicated in the 20th century are now subjects of conservation efforts as their ecological roles become understood. Apex predators (wolves, sharks) and megafauna (elephants, rhinos) that were persecuted are now recognized as keystone species. The tension between agricultural interests and conservation values is one of the defining environmental conflicts of the 21st century.

Australia's Unique Ecology

Australia's ecological uniqueness stems from its isolation: after separating from Gondwana ~45 million years ago, its fauna evolved in isolation, producing marsupials and monotremes that filled ecological niches occupied by placental mammals elsewhere. The result is a continent whose native species evolved with no exposure to Northern Hemisphere predators — making them extraordinarily vulnerable to introduced species like foxes, cats, and rabbits. Australia has the world's worst mammal extinction record: over 30 species lost since European settlement.

Major G.P.W. Meredith: The Man Who Lost to Emus

Major Geoffrey Granville Purches Meredith of the Royal Australian Artillery was the officer commanding the emu campaign — and his dispatches to military headquarters provide the most vivid primary source on the operation's failure. Meredith arrived with two Lewis guns and 10,000 rounds, expecting a straightforward campaign. Instead he found that emus instinctively divided into small groups when threatened, making concentrated fire ineffective; that they could absorb multiple rounds and continue running (their loose feather structure and low vital density made them extraordinarily difficult to kill with machine gun fire); and that the Western Australian terrain of scrub and sand made vehicle pursuit impossible. Meredith reportedly said that if the emus had a military division, they would 'face any army in the world.' He requested withdrawal after three days.

Other Human-Animal Conflicts That Did Not Go as Planned

The Great Emu War is the most famous entry in a surprisingly crowded genre: organized human military or quasi-military action against animal populations that failed spectacularly. The US Army's 1907 campaign against prairie dogs in Wyoming using poison gas was abandoned after it proved more dangerous to the soldiers than the rodents. New Zealand's decades-long campaign against possums (introduced from Australia) remains largely unsuccessful despite massive investment in aerial poison drops and bounty systems. The UK's 1950s campaign against rabbits using myxomatosis succeeded in killing 99% of the rabbit population — which then evolved resistance within a decade, with population recovery to 60% within 15 years. Australia's ongoing war against cane toads — introduced in 1935 to control beetles — is the most ecologically catastrophic example of an intervention producing a worse problem than the original.
