PERTH — Emergency services are responding to a serious public transport accident in Perth’s northern suburbs after a Transperth commuter bus slammed into a tree, leaving five passengers injured. The high-impact collision occurred just after 11:00 a.m. on Thursday, June 4, 2026 on Joondalup Drive, near Drovers Place in Wanneroo.

A major multi-agency rescue operation was triggered immediately following the crash, drawing a massive response from the Department of Fire and Emergency Services (DFES), Western Australia Police, and St John WA.

Underscoring the severity of the incident, St John WA dispatched eight separate ambulance crews to the location. A spokesperson noted that this represents an unusually high concentration of medical resources for a single traffic collision.

A DFES spokesperson confirmed that despite the structural damage to the front of the bus, no passengers were trapped inside the wreckage.

The casualties include a man in his 50s who was rushed to Joondalup Health Campus under priority "lights and sirens" conditions, while four other passengers—two women in their 40s and 60s, and two men in their 30s and 40s—are being treated for various non-life-threatening injuries.

The force of the crash left the commuter bus wedged against the tree, with debris scattered across the thoroughfare. Helicopter footage from the scene captured the scale of the emergency response paralyzing the local road network.

Main Roads WA and local police have completely closed Joondalup Drive in both directions between Burns Beach Road and Wanneroo Road. Heavy traffic gridlock has quickly built up through Wanneroo, and motorists are being strongly urged to avoid the sector and seek alternate northern routes.

WA Police remain on-site and have launched an official investigation into what caused the Transperth driver to veer off the road. Authorities are appealing to anyone with dashcam footage or information regarding the crash to contact Crime Stoppers.
