Conley, 27, will face Brisbane Magistrates Court today on two counts of murder after her girls were pulled unresponsive from the car outside a home in Waterford West about 1.35pm.

The temperature in the area at 1.30pm was 31C.

The shattered father of Darcey-Helen, who he called "Pumpkin", told The Courier Mail he was devastated, also being a father figure to Chloe-Ann.

"Darcey and Chloe were loved by anyone and everyone who met them. I absolutely adored them both," the father, who asked not to be named, said.

"Darcey had a contagious laugh and Chloe really, although they were 12 months apart, wasn't really that far behind Darcey. I think she learnt a lot off Darcey, mannerisms."

He said the pair giggled all the time and repeated everything others said.

"They were just two peas in a pod," he said.

Family and friends of accused child murderer say they made multiple attempts to alert the authorities about concerns they had for the two children.

"I know of four people that made reports to them and other agencies and nothing was done," the family member told The Courier-Mail.

"(They) just got told they would look into it and do a property check of who lived there."

Neighbours, who have paid tribute to the "gorgeous little girls", said they saw them soaking wet.

"The police were carrying the girls out … their shirts were ripped open like they'd tried to save them," one woman who did not want to be named told The Sunday Mail.

The Australian said it was understood police were investigating whether drugs had played a role in the tragedy.

The newspaper also spoke to a woman who regularly babysat the girls who said there had been previous complaints to authorities about the children being left in the car.

Detectives investigating the deaths are now seeking a new witness seen in the area on CCTV.

The man was wearing high visibility clothing and walking along Logan Reserve Rd about the same time the children's bodies were found, 7 News reports.

Police say the man is not a suspect but they believe he may have important information and are keen to speak to him.

Nine News reported it was "believed (Conley) had fallen asleep inside the home" while the children were in the car.

Queensland Police are urging members of the public who may have any information regarding the matter to contact them.

Detective Inspector Mark White said it was a very tragic incident.

"The two children exhibited signs of being exposed to extreme heat and that is forming the direction of our investigation," he said.

"We'll be speaking to quite a number of people to establish what was taken place.

"We are speaking with the parents of those children and it's just a very, very tragic incident that has occurred."

A friend of the family described the girls as "two beautiful angels".

"Darcey had a very caring heart for her sister and us all and the most amazing cuddles and kisses, and just as any toddler does, she liked to see how far she would get with being a bit mischievous," she told The Courier-Mail.

Neighbours said the family had moved in as recently as six months ago.

People have been laying flowers and tributes at the scene today.
