Teen Lifeguard's Fatal Shark Attack Ruled Instantaneous by Coroner

Eighteen months after a fatal shark attack claimed the life of 17-year-old Charlize Maree Zmuda, a coroner's report has provided closure for her family by confirming the incident was instantaneous. The attack occurred in February 2025 at an unpatrolled beach in Woorim on Bribie Island, off Queensland's Moreton Bay.

Coroner Carol Lee determined that Zmuda, a competent swimmer and volunteer lifeguard, was attacked by a bull shark measuring between 2.5 and 2.9 meters. The report found that the teen died from extensive injuries to her right upper arm, which led to an air embolism that fatally blocked her arteries. "This is a rapidly fatal event and is the most likely mechanism of death," Ms. Lee stated in her findings.

Charlize's parents, Steve and Renee Zmuda, expressed relief that their daughter did not suffer. "As a parent, my biggest fear was that she was screaming in pain, but she wasn't, it killed her instantly," Mr. Zmuda told the Courier Mail. His wife added, "It was confronting but also a relief because the details of the report confirmed it was very quick."

The swiftness of the attack meant that by the time Zmuda's friend on shore noticed a commotion, saw blood, and heard a scream, it was too late. The friend observed Charlize floating on her back with no further signs of movement.

Despite the tragedy, the Zmudas continue to advocate for a balanced relationship with the ocean. "She (Charlize) wouldn't want this to cause fear because the ocean just gave her so much joy," Ms. Zmuda said. "I think if losing Char has taught us anything, it's that we only have today, that's all that's promised."

No inquest will be held, as the coroner found that appropriate safety measures were in place at the beach. A trial of surveillance drones at Woorim Beach had concluded the day before Zmuda's death, and 18 baited drumlines were operational and had been serviced two days prior to the incident. These drumlines are used to trap sharks for euthanasia or relocation.

However, the coroner noted that shark nets are not suitable for Woorim Beach due to strong tidal currents that can render them ineffective. "Shark nets and drumlines do not provide an impenetrable barrier," Ms. Lee observed. Between January 2024 and March 2025, only four sharks, including two bull sharks, were caught in the Woorim Beach drumlines.

The shark control program underwent reforms and increased investment following Zmuda's death. "I am satisfied that an appropriate shark risk mitigation framework is in place in an attempt to reduce the occurrence of shark attack risk at our coastline in the future, with the aim of protection of human life whilst maintaining environmental stewardship," Ms. Lee concluded.

The Zmudas have expressed a desire to see SharkSmart drone technology expanded for all-weather conditions and longer deployment durations.
