The man had been boating with a group of friends and was with another man travelling in the boat as it was towed behind a car about 6pm.

The boat came off the trailer along Recreation Road near Ewing Street, flinging the two men onto the road.

One man escaped the accident with minor injuries but the 43-year-old struck his head on the bitumen and sustained severe head injuries.

A doctor who was with the group of friends and a nurse who lived nearby attempted resuscitation and kept the man alive until emergency services arrived on the scene.

The man was taken to Peel Health Campus but deteriorated quickly and died shortly after arrival.

Acting Peel traffic sergeant Mark Burton said the accident served as a warning to other motorists about the dangers of riding in boats being towed.

He said “this sort of thing could happen to anybody” and urged people to be careful.

Police are still unsure as to what exactly caused the accident and said there was no indication the driver of the vehicle was doing anything “untoward”.

Major Crash are continuing investigations.

AS WELL as the fatal accident, another crash earlier in the day resulted in two teenagers being air-lifted to hospital.

The 17-year-old female and 19-year-old male were seriously injured after the Ford Falcon station wagon they were travelling south in along Old Coast Road veered onto the wrong side of the road and clipped an oncoming caravan being towed.

The station wagon continued on into bushland, collided with a tree and flipped onto its side.

The 19-year-old unlicensed driver from Busselton escaped the crash unscathed.

Another passenger sustained a minor wrist injury.

The girl flown to hospital had suspected spinal injuries and the male was believed to have broken his pelvis.

Neither victim was considered to have life-threatening injuries.

The occupants of the vehicle towing the caravan were reported to be unharmed.

DESPITE two major crashes, acting Peel traffic sergeant Mark Burton said the traffic over the long weekend was not too bad.

“Overall drivers were pretty well-behaved,” he said.

“Of course, there were some exceptions.”

An operation launched on Saturday netted police eight drunk drivers prompting Sgt Burton to warn drivers of the dangers of drinking while on the road.

“Some people are still not getting the message,” he said.
