Despite the name sounding somewhat reminiscent of a teenage punk-rock band, the ‘Garage Girls’ were actually an elite division of women codebreakers who played an instrumental role in the Second World War.
It’s 1943 – deep in the midst of World War II, and Australian signals experts in the Central Bureau are hard at work, analysing Japanese communications. Stationed in Brisbane, they work out of Nyrambla – a lavish 1880s mansion, owned by United States General Douglas MacArthur, the supreme commander of the Allied Forces in the southwest Pacific.
But it’s not until you tread a little further, past the main house, to the shed around the back, that you find where the real work is being done. There, women work around the clock to decode enemy radio signals and to both encrypt and decrypt messages for Allied soldiers. They used British TypeX cypher machines to crack codes, providing essential intelligence to forces across the Pacific.
These women were enlisted by the Central Bureau due to labour shortages during World War II, as the men were being conscripted to fight. Coming from a wide range of backgrounds, these women – some as young as 19 – were quickly trained in a unique set of skills. Their daily lives quickly transformed from working in haberdashery and cake shops to unlocking the secrets of enemy communications, all under a heavy veil of secrecy.
The Garage Girls had a significant impact on the war effort, with their work helping pinpoint the commander of the Imperial Japanese Navy, Admiral Isoroku Yamamoto – a crucial target for United States forces, due to his direct involvement in the December 1941 Pearl Harbour attack. Yamamoto’s death was a major strategic strike and had a significant negative impact on Japanese morale. The Garage Girls also helped restore and document a large number of scavenged Japanese code books, decimating the security of the enemy’s communication channels. In fact, it is estimated that the efforts of the Garage Girls reduced the span of the war by two years and helped in forming what is now the Australian Signals Directorate.
Despite the monumental nature of their achievements, it took nearly eighty years for these women to receive proper recognition. Due to the sensitive nature of the work, details of the group’s efforts were not allowed to be made public during the thirty years following the war. Regardless, it was still not until January 2023 that the Garage Girls received any form of recognition. It was then that the three surviving members, Coral Hinds, Joyce Grace and Ailsa Hale, were awarded the Australian Intelligence Medal.
It is a well-known fact that the labour shortages during the Second World War were a huge catalyst for women entering the workforce. With women being called up into typically male-dominated roles such as manufacturing, engineering and agriculture, the lines between gender roles began to blur. However, with no one to witness the triumphs of the Garage Girls, it seems unsurprising that so little is known about Australia’s female codebreakers. And perhaps this secrecy is part of why we are still seeing such low numbers of women in cybersecurity today. More than anything, this should highlight the importance of lifting the voices of those in the industry. As we have seen through the stories of the Garage Girls, it’s hard to be role models in an industry that is actively trying to keep you hidden.
