Emergency services rushed to the Binya Street home just after 6pm on Sunday to find distraught family members performing CPR on the 20-month-old child, who was unresponsive when paramedics arrived.

It is believed the gate to the fence surrounding the above-ground backyard pool had been left open and the toddler had fallen in.

Paramedics worked to revive the child for about 30 minutes before rushing her to Griffith Base Hospital, where Emergency Department specialists continued attempts to revive her for one hour.

Tragically, attempts failed and she was pronounced deceased on Sunday night.

A crime scene was established at the home and police will continue investigations into the incident.

A report will be prepared for the coroner.

Griffith Police Crime Manager Paul Smith said the case was certainly a traumatic one for all involved.

“These are incredibly tragic circumstances,” Detective Inspector Smith said.

“Our thoughts go out to the families involved at this very difficult time.”

Detective Inspector Smith urged all parents to be extra vigilant with young children around canals, pools and dams during the warmer months.

The Griffith community has been rocked by the tragedy, so soon into the summer season.

Tributes have flooded the Griffith Police Facebook page, with dozens of locals offering their heartfelt messages to the little girl’s family.
