A young man suffered critical head injuries and fractured lower limbs in a motorcycle accident in Western Sydney this morning.

CareFlight’s rapid response helicopter was called to Tregear at around 11.00am, landing at a playground about 200 metres from the scene.

CareFlight’s specialist emergency doctor and intensive care paramedic treated the man at the scene, anaesthetising him and putting him on a ventilator before he was driven by road ambulance to Westmead Hospital in a critical condition.
