Western Australia Police's Major Crash Investigation Section has appealed for public assistance following a serious traffic collision in Australind, just north of Bunbury. Detectives are asking anyone who witnessed the incident or captured dashcam footage to come forward as they work to establish exactly what happened.

Emergency services responded to the crash after receiving reports of a serious collision on the weekend. Police officers, paramedics and other emergency responders attended the scene, where they secured the area, assisted those involved and began examining evidence. The circumstances leading up to the collision remain under investigation.

Major Crash investigators have taken carriage of the inquiry because of the seriousness of the incident. Specialist officers are analysing physical evidence from the crash scene, inspecting the vehicles involved and reviewing CCTV and dashcam recordings that may help determine the sequence of events.

Police have not publicly released detailed information about the people involved while investigations continue. Authorities said this approach helps protect the integrity of the investigation and respects the privacy of those affected.

Investigators believe members of the public may hold important information that could assist the inquiry. Drivers travelling through the area around the time of the collision are encouraged to check dashcam recordings, even if they did not witness the impact itself. Footage showing vehicle movements before or after the crash may help detectives reconstruct the events.

WA Police reminded motorists that public cooperation is often crucial in serious crash investigations. Witness statements, camera recordings and timely reporting can significantly assist investigators in establishing the facts and ensuring accurate findings.

The incident has also prompted renewed reminders about road safety across the South West. Police continue encouraging drivers to obey speed limits, avoid distractions, wear seatbelts and never drive while impaired by alcohol or drugs. Authorities say responsible driving remains one of the most effective ways to reduce serious crashes on regional roads.

Australind and the Bunbury region experience significant traffic volumes, particularly during weekends and holiday periods. Police regularly conduct road safety operations throughout the South West to improve driver behaviour and reduce the risk of serious collisions.

The Major Crash Investigation Section will continue examining all available evidence before determining the circumstances surrounding the incident. Investigators have urged anyone with relevant information, no matter how minor it may seem, to contact WA Police or Crime Stoppers.

At this stage, no further details have been released regarding possible charges or contributing factors. Police said updates will be provided if new information becomes available as the investigation progresses.

Authorities thanked members of the public who have already assisted and reiterated that community cooperation remains essential in helping investigators complete a thorough and accurate inquiry.
