A report is being prepared for the coroner after a backyard swimming pool tragedy at Bobs Farm last night.

Emergency services were called out to a home on Marsh Road around 6:40pm after a 19-month-old boy was found unconscious in the pool.

Paramedics were sadly unable to revive the boy.

A crime scene has been established as Port Stephens Police investigate the incident, but initial inquiries suggest there are no suspicious circumstances at play.
