A high-speed collision in Sydney's south claimed the lives of three men early Saturday morning. The incident occurred in Sans Souci when an Audi struck an Uber, killing the driver, a passenger, and the person behind the wheel of the Audi.

From a Gymea Bay welfare check to a high-speed collision

The sequence of events leading to the tragedy began around 12:25 am when police were called to a residence in Gymea Bay to conduct a welfare check. tamati Gilbert's partner had reportedly raised "grave concerns" regarding his mental health. As the report states, Gilbert was located sitting in his Audi in a driveway but managed to speed away before officers could engage with him.

Roughly ten minutes after fleeing the welfare check, the vehicle was captured on CCTV traveling at "considerable speeds." The Audi subsequently flipped over a concrete barrier and landed on a blue Toyota Camry on Rocky Point Road, approximately 13km away from the initial police contact.. The impact was so violent that the wreckage remained at the scene for several hours as investigators processed the site.

The lives lost in the Rocky Point Road impact

The collision resulted in the immediate deaths of three men at the scene. Among the victims was 28-year-old Seamus Duignan, who was traveling in the Uber after celebrating his birthday at a concert. His brother, Sean , described him as a "good man" who was never in trouble .

The other two fatalities included the 20-year-old Uber driver and the 42-year-old Audi driver, Tamati Gilbert. According to the report, the crash was so intense that it caused one of the vehicles to catch fire, prompting bystanders to rush to the scene with fire extinguishers in a desperate attempt to prevent an explosion and rescue those trapped inside.

A 20-year history of 120 accidents at the site

Local residents are expressing outrage and calling for immediate infrastructure changes near the Captain Cook Bridge. The community has long viewed this stretch of Rocky Point Road as a high-risk zone. One resident told Nine News that they have witnessed at least 120 accidents at this specific corner over the last 20 years of living in the area.

The crash caused significant disruption on Saturday, forcing the closure of Captain Cook Bridge and Rocky Point Road, which led to major traffic diversions. Residents are now demanding the installation of speed cameras at both ends of the bridge to curb the high-speed driving that characterizes this notorious stretch of road.

Investigating the potential impairment of Tamati Gilbert

While the physical cause of the crash was the high-speed impact, detectives are still working to determine if external factors contributed to the driver's behavior. Police are currently investigating whether Tamati Gilbert was under the influence of drugs or alcohol at the time of the collision.

Several questions remain regarding the transition from the welfare check to the crash site. It is currently unverified how the driver's mental state influenced the decision to flee the Gymea Bay residence. A formal report will be prepared for the coroner to provide a definitive account of the circumstances surrounding the deaths.
