Police have been told to follow their "gut instinct" after a Kiwi father killed his two children in the three hours it took for officers to respond to their mother's desperate call for help.
A coroner in Perth has delivered her findings into the deaths of 5-year-old Zaraiyah-Lily Headland and 3-year-old Andreas Headland, who were found dead at in October 2016.
New Zealander Jason Craig Headland - who was also found at the home with self-inflicted injuries - pleaded guilty to their murders and was sentenced to life in prison, with a minimum of 31 years to be served.
Coroner Sarah Linton said the inquests were "two of the worst I have dealt with," the West Australian reported.
Their murders were an act of revenge against his wife, Anatoria Takiwa, who had asked him for a divorce days earlier.
The inquests previously heard that the children's mother, formerly of Paraparaumu, had gone to Joondalup police station to request a welfare check after she received a disturbing phone call from her estranged partner.
In the call, Headland said: "I'm going to hurt you ... I'm going to break your heart into 50 million pieces. Say goodbye to your kids. This is the last time you're going to speak to them."
The coroner found that the outcome might have been different if police had trusted their instincts after a police recruit admitted she had a "weird feeling" when Takiwa and her friend reported the chilling phone call.

It took three hours to send a car to the property for a welfare check and when police arrived they found the children dead.
"I can't help wondering whether things might have been different if [the recruit] in particular, as she had the strongest instinctive sense of concern, had been allowed to rely more on her gut instinct... I am not suggesting that the deaths would definitely have been averted, as it is clear Jason had formulated a plan from at least early afternoon, and was intent on putting that plan into effect," Linton said.
"In the end, I am left with a feeling of disquiet, as the police recruit who took the initial report had a very strong, instinctive feeling that something was amiss, and it was through the advice of her superiors, and following police procedures, that she was directed to take a less direct path to checking on the children's welfare."
The recruit had initially called Headland, who promised to bring the children to the station, but when he failed to arrive the recruit tried to call him back before calling Takiwa and being told he could be at the marital home.
A job was then logged with a lower priority, meaning police gave themselves a full hour to respond.
In that time, Headland had crushed sleeping tablets into his children's juice before asphyxiating them.
During the inquest, Takiwa said she went to police because "I just wanted to make sure the kids were ok," and "I didn't want him to be alone with them after that phone call."
Senior Constable Christine Darlington, who had been at the station on the fateful day, started to cry as she addressed Takiwa.
"We'd like to extend our sincerest condolences for the tragic loss of your beautiful children," she said.
"We joined police to save lives and make a difference. On this rare occasion, we were unable to do that. We too carry that burden every day. Please accept our deepest sympathy for your loss."
