The secret war of Sybil Beck

On the surface, Sybil Joan Brady (née Beck) was a quiet Brisbane woman. A mother. A grandmother. A great-grandmother. Someone who briefly mentioned the war, and then said nothing more.  

In fact, if you spoke to her husband or children about her life growing up, they barely knew she had served at all.  

It was only after Sybil’s passing in November 2025, aged 101, that her incredible story came to light with the help of Sandgate RSL Sub Branch.

Hidden histories 

Jim Lakey, a member of Sandgate RSL Sub Branch, conducted Sybil’s poppy service after she had passed. It’s a role he’s performed many times and takes very seriously. Before he steps up to speak, Jim does his homework. 

“I only say things I can verify to be 100% true,” Jim explains. “And then I turn those facts into a bit of a story to tell the family about the service of their loved one.” 

It was whilst researching Sybil in the National Archives that Jim discovered why exactly she had kept her service history quiet, stopping him in his tracks.  

Born in 1924, Sybil was 15 years old when World War II (WWII) broke out, finding work as a typist for a United States Colonel based in Brisbane as part of General Douglas Macarthur’s staff. 

When the Americans moved on and her role came to an end, Sybil knew she wanted to keep working, and so her career followed her into the Air Force.  

On 16 February 1944, Sybil enlisted in the Women’s Auxiliary Australian Air Force and pledged to serve for the duration of the war and an additional 12 months – a remarkable commitment from someone still in her late-teens at a time when no-one could guarantee when, or if, the war would end. 

What came next was something Sybil would carry quietly for the rest of her life.

A life bound by secrecy 

Based on her skills and character, Sybil was selected to join one of the most secretive operations of WWII: the Central Bureau.  

Established in Brisbane by General Douglas Macarthur on 15 April 1942, the Central Bureau was a joint American and Australian signals intelligence organisation – Australia’s very own Bletchley Park. Its mission was to intercept and cryptanalyse Japanese Army and Air Force communications to provide intelligence to Allied Forces in the Pacific.  

Sybil was a recorder – a role that placed her at the centre of some of the most sensitive intelligence work during the war. It also meant she signed the Official Secrets Act, forbidding her to talk about her service until well into the 21st century. The precise nature of her knowledge and contributions is known only to her and a select few others. 

“She may not have carried a rifle, but her work helped save the lives of countless Australians and members of the Allied Forces,” Jim explains.

“W 102063 Sybil Joan Beck” 

Jim pieced Sybil’s story together through a combination of official service records in the National Archives of Australia, and careful, methodical research.  

For him, learning about Sybil was a “wow moment”, and her family agrees. 

“We never heard anything about what mum did in the war growing up,” Sybil’s daughter Jan Dauth reflects. 

“She was always a bit sad on ANZAC Day, but she said she’d lost a couple of friends. That was all.” 

As part of his research, Jim discovered that Sybil was eligible for medals for her wartime service. He helped her family with the evidence and application and Sybil was posthumously awarded the War Medal 1939-1945, known as the Commonwealth WWII Victory Medal, and the Australia Service Medal 1939-1945. Both are inscribed “W 102063 SYBIL JOAN BECK” and her family received them with immense pride.  

“It was such a huge moment finding out about her part in the war, even my dad didn’t know” Sybil’s son Mark Brady says, “We always knew she was a strong, intelligent woman.”

Gone but not forgotten 

For Jim, Sybil’s story is one of many that he has helped to uncover.  

Since he started conducting poppy services for Sandgate RSL Sub Branch in 2023, he has brought the same careful dedication to each one – turning a veteran’s service record and archival paperwork into a living tribute at a time when a family needs it most.  

It is this work, unhurried, voluntary and deeply human, that sits at the heart of what Sandgate RSL Sub Branch does for its community.  

Veterans like Sybil kept their secrets for decades; it’s Sub Branch members like Jim Lakey who makes sure those secrets aren’t lost forever. 

“If we don’t tell their stories, who will?” Jim asks.
