An Australian Coroner's court has heard the mother of two toddlers who died after being left in a hot car often left them there.
Queensland woman Kerri-Ann Conley left her daughters, Darcey-Helen, two, and Chloe-Ann, 18 months old, inside a black station wagon with no shade and all the windows shut.
The two girls were found dead nine hours later, on November 23 2019. Police recorded temperatures of over 50C inside the car and the girls showed evidence of extreme heat exposure.
An inquest into the deaths is set to be held in April 2024 and will look at any failings in the lead-up to the girls' deaths.
A report obtained by 9News detailed worrying behaviour presented by Conley just 10 days before the children's deaths.
The report stated back in 2018, Conley told Child Safety Services she wanted to swap her unborn child, Chloe-Ann, for an iPhone and later that year she also told Child Safety Services she had been using methamphetamine.
It also found three weeks before her death, Darcy-Helen was seen running around with her mother's bong in her mouth. The toddler was taken to the hospital where she was found to be underweight, pale and suffering from diarrhoea.
A week later on November 13, 2019, police received a report Conley was selling and using meth while her children were locked in another room.
However, despite the warning signs, Conley was deemed to be a "willing and able" parent.
The report said child safety officers did not further look into Conley's case due to "workload demands".
At a pre-inquest hearing on Monday, counsel assisting the coroner, Simon Hamlyn-Harris, told the Coroners Court it will consider the responses by Child Safety Services, Logan Hospital and Queensland Police Service, and hear from a psychiatrist about drug usage and parenting.
Police investigations revealed Conley had a habit of leaving the girls inside the car for long periods of time and that she was a regular user of methamphetamine, Hamlyn-Harris said.
She was described as a mother whose behaviour put her daughters at a "significant risk of harm".
Conley was sentenced to nine years behind bars earlier this year after pleading guilty to two counts of manslaughter.
