Emergency services raced to the house in Derribong Drive at 1.15pm after receiving a call that a 12-year-old boy had fallen into a swimming pool in the backyard of the property.

It is understood he may have hit his head on the side or bottom of the pool.

Ambulance crews began CPR and quickly called for the CareFlight helicopter, which deposited a doctor and paramedic on the street before landing at nearby Sheargold Park.

The boy was transported to Wollongong Hospital where he was unable to be revived.

A brief will now be prepared for the coroner.
