Investigations are continuing following an accident involving a hang glider at Stanwell Park early this week.
Police believe the 52 year old man was intending to hang glide from Bald Hill to Stanwell Park Beach around 5pm on Monday 12 March.
Officers from Wollongong Police have been told the hang glider appeared to stall and then clipped trees that stand about 30-40 metres high at the northern end of the park.
The hang glider then fell from a height of 20 metres to the ground.
Ambulance paramedics and council lifeguards treated the man at the scene for suspected head, jaw and lung injuries.
After being stabilised, the man was airlifted to St George Hospital in a serious condition.
