A 25-year-old motorcyclist is in a critical condition following a crash with a wedding car at Greystanes on Saturday afternoon.
Shortly before 2pm, at the request of the paramedics, a CareFlight helicopter landed in a golf course next to the crash on Old Prospect Road near Kootingal Street.
The CareFlight doctor said the motorcyclist from Bexley was with a group of bikers when he collided with the car.
The crash left the man with chest and critical head injuries.
The doctor placed the man in an induced coma, with a ventilator to control his breathing, then had him conveyed to Westmead Hospital.
The car's passengers escaped injury.
