Coronial findings released this week into the 2014 death of 18-month-old Kobie Ryder Blackaby revealed the toddler drowned after falling into an inflatable pool in his backyard.

Royal Life Saving Society Tasmania executive director Paula Robertson said the incident was a “strong reminder” for the community to remain vigilant when it comes to pool safety.

“Children under the age of five-years-old most commonly drown in home pools,” Ms Robertson said.

“For every drowning death in that age group there are approximately three more children admitted to hospital as a result of an “immersion incident” and a significant proportion of these (one-fifth) suffer brain damage.”

In her report, Coroner Olivia McTaggart said an ambulance was called to a Hobart home on February 25, 2014 after Kobie’s father Timothy Blackaby found him floating in the pool in their backyard.

Mr Blackaby, a friend and a neighbour each attempted CPR as Kobie was not breathing and did not have a pulse.

The toddler was later pronounced dead at the Royal Hobart Hospital.

Ms McTaggart said "there was no fencing preventing entry to the pool", which was 600 millimetres high and 495 millimetres deep. The pool was not fully inflated at the time of the incident.

“It is likely that Kobie leaned against the side of the pool which then collapsed causing him to fall in. Once inside the pool, the inflatable rings would have returned to their normal position preventing his escape,” Ms McTaggart said.

"I recommend that the responsible state and local government bodies incorporate into existing water safety awareness and education strategies, a public education and awareness campaign highlighting the requirement for approved pool fencing relating to the installation of portable and inflatable pools.”

In Tasmania, pools deeper than 300 millimetres require fencing.
