A 42-year-old motorcycle rider has died following a serious road accident on the Great Southern Highway near Katanning in Western Australia. Police are investigating the circumstances surrounding the collision and have appealed to members of the public for information.

According to Western Australia Police, the crash occurred shortly before 7 pm on Tuesday, 3 November 2026. A red and black Harley-Davidson motorcycle collided with a white Toyota Corolla on the Great Southern Highway, near the intersection of Greenhill Road North.

Emergency services attended the scene after receiving reports of the collision. The motorcycle rider, a 42-year-old man, suffered critical injuries and died at the scene despite the emergency response.

The driver of the Toyota Corolla survived the collision and was transported to Katanning Hospital for medical treatment. Authorities have not released further details about the driver's condition.

Major Crash Investigators are now examining the circumstances that led to the accident. Their investigation is expected to consider the movements of both vehicles, the condition of the roadway and other available evidence.

Police are particularly interested in speaking with anyone who may have witnessed the collision or observed either vehicle shortly before the crash. Investigators are also encouraging motorists who travelled along the Great Southern Highway around the time of the incident to check their dashcam recordings.

The Great Southern Highway is an important transport route connecting regional communities in Western Australia. It is regularly used by local residents, agricultural businesses, commercial vehicles and travellers moving between towns.

Katanning is an important regional centre in the Great Southern region, serving surrounding agricultural communities. Road safety remains a significant concern for regional residents, particularly on highways where vehicles travel at higher speeds and journeys can involve long distances.

Motorcycle riders are particularly vulnerable in road collisions because they have considerably less physical protection than occupants of cars. Even a collision involving a relatively small vehicle can result in devastating injuries.

Police regularly remind motorists to remain alert, maintain safe distances and pay attention to other road users. Drivers should check carefully before turning or changing lanes and should always remain aware of motorcycles approaching from different directions.

The latest fatal crash has again highlighted the importance of safe driving across regional Western Australia.

Investigators are continuing their inquiries to establish exactly how the collision happened. No conclusions about responsibility or the cause of the crash have been announced.

Anyone with information, dashcam footage or CCTV recordings relevant to the incident is urged to contact Crime Stoppers Western Australia on 1800 333 000 or submit information online.
