'A Beautiful Soul': Toddler Drowns In Backyard Swimming Pool

It's the latest in a series of horror drownings this summer, which are seeing Australian lifesavers "pushed to their limit".

Emergency services were called to a home in Greenbank Drive, Werrington Downs around 8pm on Wednesday after a toddler was found face down in the family backyard pool.

The lifeless tiny body of Octavia Ann -- the only child of Rachel and Darren Rothnie, just 20 months old -- was treated by paramedics at the scene, but tragically, she died on the way to Nepean Hospital.

Neighbour Shaylea Fahey told 10 News First they're devastated that such an unimaginable tragedy could happen to such a beautiful family.

"She was a gorgeous little girl and her parents are amazing people they don't deserve this," Fahey said.

"She was a sweet girl she loved everyone."

A mother of three little boys herself, Fahey said her boys were great friends with little Octavia and they still don't know what's happened.

"They loved each other, she used to always run over and say hi to the boys. She was a beautiful soul," Fahey said.

The toddler's death comes just two hours after two other young children were pulled from a lagoon by a member of the public at Avoca Beach on the NSW Central Coast.

A 4-year-old boy remains in an induced coma fighting for his life at Westmead Hospital, while the 5-year-old girl is in a stable condition in Gosforth Hospital.

It's been a summer from hell in the water, with the national death toll at around 55 people. It's up significantly from 2018, and being recorded across all waterways -- beaches, lakes, rivers and pools.

Surf Lifesaving NSW CEO Steven Pearce said it was pushing those charged with keeping us safe in the water "to the limit".

“The tragedies unfolding every day across our waterways is heart-breaking for families, communities and our rescuers. We will continue to do what we can to keep people safe but we need your help,” Pearce said.

“We are seeing more and more fatalities and near misses and our lifesavers and lifeguards are being pushed to the limit."

Police are also searching for a 21-year-old man, who has been missing in the Murray River near Albury since 7pm on Wednesday night.
