What was the cause of Sam Backo’s death?

Role of melioidosis

  • Sam Backo died after a three-month battle with melioidosis, a bacterial tropical soil infection (ABC News).
  • The disease is commonly found in soil and water in tropical and subtropical regions, and Queensland had recorded 35 melioidosis deaths in 2025 alone (7NEWS).

Heart complications

  • Backo also suffered from ongoing heart issues, including an open-heart surgery in 2023 and the installation of a pacemaker in July 2025 (SBS NITV).
  • He had an implantable cardioverter defibrillator after the 2023 surgery (SBS NITV).
Bottom line: Backo died from a combination of melioidosis and heart complications, with the infection likely contracted while swimming in a creek after a ride on his Harley Davidson motorbike (SBS NITV). The implication: a rare infection exploited a weakened heart, ending a robust life prematurely.

What disease did Sam Backo have?

Melioidosis explained

Melioidosis is caused by the bacterium Burkholderia pseudomallei, which lives in soil and water in tropical regions (ABC News). It can cause severe pneumonia and sepsis, and is often fatal if not treated early.

How melioidosis is contracted

  • People typically contract the disease through contact with contaminated soil or water, especially through cuts or inhalation of dust (7NEWS).
  • Backo is believed to have contracted melioidosis while swimming in a creek after riding his motorbike (SBS NITV).
The catch

Melioidosis is a rare but deadly disease — and it’s on the rise in tropical Queensland. For locals and travellers, the risk is real: a swim in a creek can turn into a life-threatening infection.

Who did Sam Backo play for?

Club career: Canberra Raiders

Backo debuted for the Canberra Raiders in 1985 and played for the club until 1991, winning the 1989 NRL premiership (Wikipedia). He also had a brief stint with the Brisbane Broncos later in his career (ESPN).

State of Origin: Queensland Maroons

Backo represented Queensland in 12 State of Origin matches between 1988 and 1991, becoming a key figure in the Maroons’ early dominance (ESPN).

International career: Australia

He played 10 Test matches for Australia, and was named a member of the Indigenous Team of the Century (ESPN). The pattern: a prop who dominated at every level, from club to state to national representation.

Bottom line: Backo was a prop who terrorised opposition packs for the Raiders, Maroons, and Kangaroos — and his legacy is cemented in the Indigenous Team of the Century.

How many children did Sam Backo have?

Children and family

Sam Backo had eight children, some from his first marriage and others from his second (SBS NITV). The exact number from each marriage is not publicly known.

What to watch

The family’s privacy has been respected; few details about his children’s names or ages have been released.

Who is Sam Backo’s wife?

Second wife and family support

At the time of his death, Backo was married to his second wife, whose name has not been publicly disclosed (SBS NITV). He was previously married to a first wife, also unnamed in public records.

Bottom line: Backo’s family life remains largely private, but his wife was by his side during his final months in hospital.

Quotes

Sam Backo’s death is a stark reminder that even the strongest among us can be felled by a microscopic enemy. For the rugby league community in Queensland, the loss is profound — but the broader lesson is for anyone who lives in or visits the tropics: melioidosis is real, and it’s increasingly deadly. For public health authorities in northern Australia, the challenge is clear: better awareness, faster diagnosis, and more aggressive treatment, or the death toll will keep climbing.
