A MOTORCYCLIST has been killed after colliding with a kangaroo on a major highway in Sydney’s west early this morning.

About 1:20am today, officers from the Nepean Police Area Command were called to the M4 near Claremont Meadows, after reports that a male motorcyclist had been found critically injured in the westbound lanes of the motorway.

It is understood the 38-year-old man was riding his motorbike near the Mamre Rd off-ramp when it collided with a kangaroo that was crossing the motorway, with the resulting impact forcing the rider into a nearby railing.

The man was seen lying near the centre safety rail about 20 metres from the body of the deceased kangaroo.

Bystanders and police attempted to administer first aid but were unable to revive the severely injured rider who died at the scene.

Police closed the motorway westbound for almost five hours while the Crash Investigation Unit gathered evidence, but roads have since been reopened with no delays to traffic.

Another motorcyclist is lucky to have escaped with minor injuries after swerving to avoid a fox on a different highway near Gerringong later in the morning.

About 5:10am today the motorcyclist was travelling south on the Princes Hwy near Willow Vale when he made an evasive manoeuvre to narrowly avoid a fox on the road, and crashed the motorcycle.

An oncoming car then smashed into the bike, causing a fire to break out.

Firefighters from Fire and Rescue NSW attended the scene and extinguished the blaze and the male rider did not require hospitalisation.
