Who Invaded Australia And Why?

which countries invaded australia

Australia has never been successfully invaded, however, there have been attempts to do so, most notably during World War II by Japan. The Japanese Navy proposed invading Northern Australia in 1941, but the Army rejected this idea as impractical. Despite this, Japan carried out air raids and submarine attacks on Australia, causing widespread fear and leading to an expansion of Australia's military and war economy. The only foreign power to have successfully invaded and occupied parts of Australia was Britain, which began with the arrival of the First Fleet in 1788, leading to the gradual dispossession of Indigenous Australians from their land.

Japan's proposed invasion of Australia during World War II

Australia was never invaded by another country, but it came under threat during World War II. After the fall of Singapore in February 1942, the Australian government, military, and people feared a possible Japanese invasion. This led to an expansion of Australia's military and war economy, as well as closer ties with the United States.

Japan's success in the early months of the Pacific War, which began with the bombing of Pearl Harbor in December 1941, led elements of the Imperial Japanese Navy to propose invading Australia. In December 1941, the Navy suggested including an invasion of Northern Australia as one of Japan's "stage two" war objectives after Southeast Asia was conquered. This proposal was most strongly advocated by Captain Sadatoshi Tomioka, head of the Navy General Staff's Planning section. He argued that the United States was likely to use Australia as a base to launch a counter-offensive in the South-West Pacific.

The Japanese Army, however, opposed the Navy's proposal as impractical. Prime Minister Hideki Tojo also consistently rejected the idea, preferring to force Australia to submit by cutting its lines of communication with the US. The Army believed that invading Australia would overextend their defence lines and require a large number of troops, which they were unwilling to release from Manchuria. They also feared Soviet entry into the Pacific War and wanted to keep the option open for invading Siberia.

There was disagreement between the Army and Navy on the number of troops needed for an invasion. In December 1941, the Navy estimated that a force of three divisions (45,000-60,000 men) would suffice, while the Army calculated a need for at least ten divisions (150,000-250,000 men). The Army also disagreed with the Navy's proposal to limit the invasion to securing enclaves in the north, believing that any invasion would have to involve the entire Australian continent, which was beyond Japan's capabilities.

While Japan never attempted a full-scale invasion of Australia, they did carry out air raids and submarine attacks. Japanese aircraft bombed towns and airfields in Northern Australia on 97 occasions during 1942 and 1943. Japanese submarines operated in Australian waters from January 1942 until July 1944, and a Japanese reconnaissance party landed in Western Australia in January 1944 to investigate reports of Allied base-building.

The fall of Singapore in 1942

No country has successfully mounted an invasion of Australia. However, in 1942, the fall of Singapore to Japanese forces had a profound impact on Australia and its defence strategy.

In the 1920s, the Australian government, led by Prime Minister Stanley Bruce, believed that a naval base in Singapore—the core of the Singapore Strategy—would be the most cost-effective defence plan. The base was massive, covering 54 square kilometres, and could accommodate a large British fleet that could defend Australia and New Zealand from a Japanese invasion. However, when World War II broke out in 1939, Britain focused on defending itself and the campaign in North Africa, sending only two battleships to stop the Japanese advance. These battleships were quickly sunk on 10 December 1941.

The Japanese forces reached Singapore in just two months, advancing from their landing point in Kuala Lumpur, Malaya, which they had captured in December 1941. Singapore was poorly defended, with no planes or ships left to protect it from Japanese bombing. The British and Allied forces, including Australians, were spread too thinly across the island to effectively resist the Japanese when they landed on 8 February 1942. The city of Singapore was bombed at will, and despite being heavily outnumbered, the Japanese moved swiftly. With one million civilians trapped in the city and water supplies dwindling, British commander Lieutenant General Arthur Percival surrendered on 15 February 1942.

The fall of Singapore was a devastating blow for the British Empire, with Prime Minister Winston Churchill calling it the "worst disaster and largest capitulation in British history". About 80,000 to 90,000 British, Indian, Australian, and local troops became prisoners of war, and thousands died from neglect, abuse, or forced labour. The Japanese occupied Singapore until the end of the war, and the fall of this supposedly impregnable fortress shattered the British Empire's prestige and sense of permanence in the region, ultimately contributing to the end of colonialism in the post-war period.

For Australia, the fall of Singapore was a disaster and a turning point. Australia lost almost a quarter of its overseas soldiers, with 15,000 captured and 7,000 later dying in captivity. The vulnerability of Australia's homeland became starkly apparent, and the country began to reconsider its alliance with Britain, turning instead to the United States for support. Prime Minister John Curtin announced in his 1942 New Year's address:

> Without any inhibitions of any kind, I make it clear that Australia looks to America, free of any pangs as to our traditional links or kinship with the United Kingdom … we shall exert all our energies towards the shaping of a plan, with the United States as its keystone, which will give our country some confidence of being able to hold out until the tide of battle swings against the enemy.

Indeed, the fall of Singapore marked the beginning of the Australian alliance with the United States, a partnership that endured through multiple wars and remains a cornerstone of Australia's security policy.

Attacks on continental Australia during World War II

Japanese aircraft bombed towns and airfields in Northern Australia on 97 occasions during 1942 and 1943. Darwin experienced its first air raid on 19 February 1942, involving over 260 aircraft. Subsequent raids were carried out with forces of 30 to 40 fighters and bombers. Most of the raids occurred during the day, but there were also some small-scale night attacks. In total, there were 64 air raids on Darwin, with the last one occurring on 12 November 1943. Air attacks also took place in other parts of northern Australia, as far east as Townsville in Queensland.

In addition to air attacks, there were submarine offensives against shipping off the Australian east coast from May to July 1942 and January to July 1943. Sydney Harbour came under direct attack from Japanese midget submarines in the early hours of 1 June 1942. HMAS Kuttabul, a converted ferry being used as a troop sleeper, was hit and sunk, resulting in the deaths of 21 sailors, including 19 Australians and two members of the UK's Royal Navy.

The only Japanese force to land in Australia during World War II was a reconnaissance party that landed in the Kimberley region of Western Australia on 19 January 1944. The party consisted of four Japanese officers on a small fishing boat investigating reports of potential Allied base-building in the region. Upon returning to Japan, the junior officer who commanded the party suggested using 200 Japanese prison inmates to launch a guerrilla campaign in Australia. However, this idea did not come to fruition.

The threat of a Japanese invasion caused widespread fear in Australia after the fall of Singapore in February 1942. The Australian government, military, and people expected an imminent invasion, leading to an expansion of the country's military and war economy, as well as closer links with the United States. Despite these fears, it is important to note that Japan never intended to invade Australia and did not have the capacity to do so in February 1942.

The British invasion of Australia in 1788

The British invasion of Australia, which began in 1788, was a complex and multi-faceted event that had a significant impact on the country's history and the indigenous populations that resided there. The invasion was driven by a range of factors, including imperial expansion, economic ambitions, and the establishment of a penal colony.

In January 1788, the First Fleet of British ships arrived at Botany Bay, marking the beginning of the British invasion and colonisation of Australia. Led by Lieutenant James Cook, who had claimed the land for Great Britain in 1770, the fleet soon moved to Port Jackson, now known as Sydney Harbour. The colony was formally proclaimed by Governor Phillip on February 7, 1788, and included the territory of New South Wales, which encompassed more than half of mainland Australia and adjacent islands.

The British invasion of Australia was characterised by the establishment of penal colonies, with an estimated 160,000 criminals transported to colonies in New South Wales, Van Diemen's Land (later Tasmania), and Western Australia. The invasion also resulted in the dispossession and genocide of indigenous peoples, with an estimated one million individuals displaced and their cultures disrupted due to introduced diseases, violence, and the loss of traditional lands. The spread of British settlement led to an increase in inter-tribal Aboriginal conflict as more people were forced into closer quarters with other tribes.

To maintain control and civil order, British troops were stationed in the colonies until 1870. Their primary role was to guard against external attacks and suppress resistance from both the convict population and the Aboriginal nations. Despite their presence, colonial military forces were also established, with local male settlers trained in musketry and military drills to assist in suppressing uprisings and maintaining order.

The colonisation of Australia from an Aboriginal perspective

Australia has a long and complex history of colonisation, with Aboriginal people facing oppression and displacement since the arrival of British and European settlers in 1788. From an Aboriginal perspective, the colonisation of Australia was a devastating event that disrupted their way of life and culture, which had thrived for thousands of years.

Prior to colonisation, the Aboriginal people lived in harmony with the natural environment, with a deep spiritual connection to the land. Their survival was dependent on their intimate knowledge of the land, its resources, and sustainable practices. The Aboriginal lifestyle was centred around kinship with nature, where every action, from hunting to shelter-building, was steeped in ritual and spirituality.

However, with the arrival of British and European colonists, this delicate balance was shattered. The colonists viewed the land as 'terra nullius', or 'no one's land', despite the thriving Aboriginal communities that inhabited it. This belief in terra nullius was based on the assumption of European cultural superiority and the ignorance that there were few 'natives' along the coast. As a result, Aboriginal land was seized, families were torn apart, and a drastic decline in the Aboriginal population occurred.

The colonisation of Australia led to the introduction of foreign diseases, such as smallpox, influenza, and measles, which decimated the Aboriginal population. Additionally, violent massacres, such as the Myall Creek Massacre in 1838, further reduced the Aboriginal population and caused widespread fear and trauma. The Aboriginal people were often compared to fauna, and their lives were deemed expendable in the pursuit of farming and grazing land development.

Furthermore, it is important to acknowledge that the impacts of colonisation are still felt today. Aboriginal sites and cultural artefacts are under constant threat from development, vandalism, and natural erosion. Additionally, the lack of written historical records from an Aboriginal perspective has resulted in a loss of knowledge and understanding of their rich history and culture.

Yes, apart from Japan, Axis Powers, including Germany, carried out attacks on Australia during the war. German surface raiders and submarines operated in Australian waters, sinking merchant ships and the HMAS Sydney.

According to international law, an invasion is defined as the entry by force by one sovereign into the territory of another sovereign. From an Aboriginal and Torres Strait Islander perspective, the British colonisation of Australia in 1788 can be considered an invasion as it led to the gradual dispossession of Indigenous people's land.
