The Wanda Beach Murders: The Mystery which has haunted Australia for more than 60 years

By Lily Constable

In January 1965, two teenage girls set off for a day at Sydney's Cronulla Beach but never returned home. More than 60 years later, the murders of Maryanne Schmidt and Christine Sharrock remain one of Australia's most haunting unsolved cases.

The discovery of the girls' bodies at Wanda Beach shocked the nation and sparked what was, at the time, Australia's largest homicide investigation. Despite decades of investigations and thousands of leads, nobody has ever been convicted.

So what happened on that summer day in 1965?

The Victims

Maryanne Schmidt and Christine Sharrock were both 15 years old and lived next door to each other in Sydney's western suburbs. The girls shared a close friendship and enjoyed spending time together, particularly at the beach. Family and friends described them as quiet and respectful teenagers.

Only days before they were murdered, the girls visited Cronulla Beach on New Year's Day. During the trip, they wandered north to Wanda Beach, a quieter stretch of coastline that would later become central to the investigation.

The following day, Maryanne returned to the area with her siblings. During the outing, she spent several hours away from the group before later telling them she had walked back to Wanda Beach. She never explained why.

The Final Day

On 11 January 1965, the girls travelled to Cronulla Beach with Maryanne's younger siblings after postponing the outing due to poor weather.

Before leaving home, Christine reportedly told her grandmother she wanted to walk through the Wanda Beach sand dunes. Although her grandmother discouraged the idea because of the younger children, Christine remained determined.

The group boarded a train at about 8.30am. During the journey, witnesses reported seeing the girls speaking with a teenage boy, although it remains unknown what they discussed.

When they arrived at Cronulla Beach, poor weather had closed the beach, prompting the group to walk towards the rock wall. At one point, Maryanne's brother saw the girls talking with another teenage boy who was collecting crabs with a spear.

Later that afternoon, the younger children became tired. Maryanne and Christine told them they would retrieve their belongings but instead walked further into the Wanda Beach sand dunes.

They were never seen alive again.

The Last Known Sighting

About 10 minutes after the girls disappeared, Maryanne's younger brother went looking for them.

He later told police he saw the girls speaking with a teenage boy believed to be about 16 years old. The boy was described as tall, tanned and wearing a grey tracksuit, with a blue towel draped around his shoulders. Witnesses said he asked the girls their names.

Approximately 10 minutes later, the same boy was seen leaving the sand dunes alone with the blue towel wrapped around his neck.

He later became known as the "Blue Towel Boy".

More than six decades later, his identity has never been confirmed.

The Discovery

The following morning, the bodies of Maryanne Schmidt and Christine Sharrock were discovered partially concealed in the Wanda Beach sand dunes.

Their deaths shocked Australia and triggered what was then the country's largest homicide investigation.

Police interviewed thousands of people and followed countless leads, but no one was ever charged.

The Mystery Continues

The identity of the Blue Towel Boy remains one of the biggest unanswered questions in the case. Witnesses placed him with the girls shortly before they disappeared, yet despite decades of investigations, he has never been identified.

More than 60 years later, the Wanda Beach murders remain unsolved. Advances in forensic science continue to provide hope that answers may one day emerge, but until then, the deaths of Maryanne Schmidt and Christine Sharrock remain one of Australia's most enduring cold cases.
