Three people have died and two are in a life-threatening condition after a spate of crashes on Queensland roads on the Easter weekend.  

A 31-year-old Palmerston man driving a quad bike died in a crash at East Palmerston, south of Cairns, on Saturday afternoon. 

Police said initial investigations indicated about 5pm the green Kawasaki was travelling along Pullom Road when it lost control and hit a pole. 

The rider was declared dead at the scene. 

Just over an hour later, two motorbikes were involved in a serious crash in Killarney, east of Warwick, leaving one man in a life-threatening condition. 

Police said about 6:20pm a Honda 250 motorbike and Kawasaki ZR900D motorbike collided on Spring Creek Road.

The rider of the Honda, a 65-year-old Killarney man, suffered life-threatening injuries and was airlifted to Princess Alexandra Hospital in a critical condition.

The rider of the Kawasaki, a 21-year-old Lowood man, sustained minor injuries and was assessed at the scene.  

Half an hour later, a motorbike and car were involved in a separate crash in Brisbane’s bayside. 

A black Honda motorbike was travelling along Boundary Road in Thornlands before it collided with a white Kia Cerato turning right from Affinity Way. 

The rider, an 18-year-old Redland Bay man, was transported to Princess Alexandra Hospital with life-threatening injuries. He later passed away.

The driver of the Kia, a 24-year-old Acacia Ridge man, was not injured. 

Police are investigating whether speed was a contributing factor in the crash. 

A 51-year-old Victorian woman has also died, after a ute and car crashed head-on along School Rd in Logan, south of Brisbane. 

About 9pm, a silver Ford Falcon ute was travelling east along School Rd when it crashed with a grey Ford Focus travelling in the opposite direction.

The woman, who was a passenger in the Ford Focus was pronounced dead at the scene. 

Queensland Ambulance Service said a two-year-old girl was taken to Queensland Children’s Hospital with significant head injuries in a potentially life-threatening condition. 

The Focus driver, a 28-year-old Goodna man, was not injured. 

The driver of the ute, a 17-year-old Logan Reserve woman, was also not injured. 

Police are appealing for anyone with information on any of the crashes to come forward as investigations continue. 

So far this year, at least 80 people have lost their lives on Queensland roads. Last year, to April 1, the road toll was 59.
