The father of one of two girls who died after being left in a hot car has issued a heart-wrenching tribute.
The children were pronounced dead on Saturday. The vehicle was reportedly parked in front of the family's south Brisbane property as the temperature outside surpassed 30C.
Their 27-year-old mother has been charged with two counts of murder.
Two-year-old Darcey Conley's father - who wishes to remain anonymous - described his daughter and one-year-old sister Chloe-Ann as "two peas in a pod".
He told Courier-Mail the girls would have been inseparable when they got older, and considered himself a "father figure" to Chloe.
"Unfortunately, we don't get to see them grow into beautiful young people."
Tributes of flowers and kids' toys have been placed against the front fence outside their home.
"There's a shrine outside the house because people don't know what else to do," Australian correspondent Jason Morrison told The AM Show.
"It's a sort of feeling, that perhaps they could have done something if only they'd known."
A family friend told 9News she hopes justice will be served.
The mother will appear in Brisbane Magistrates Court on Monday.
