Australian 5yo dies after being found unresponsive in hot car

A five-year-old Australian girl, who was found unresponsive inside a car earlier this week, has died.

At around 4:30pm on Tuesday (local time), emergency services were called to a home in Tanilba Bay, Port Stephens, located in New South Wales' Hunter Region. The girl was found unresponsive inside a vehicle parked in the driveway of her family's home.

She was placed in an induced coma after being airlifted to John Hunter hospital in a critical condition, 7 News reports.

NSW Police have confirmed the five-year-old died early on Sunday morning.

According to temperature records, Tanilba Bay reached a high of 37.5 degrees shortly before 3pm on Tuesday.

It remains unclear how long the girl was left inside the sweltering vehicle.

Her death comes just one week after two sisters, aged one and two, were found dead after being "exposed to extreme heat" inside an airless black station wagon. The car had been parked in front of the family's property in Logan, south of Brisbane. 

Their mother, 27-year-old Kerri-Ann Conley, has been charged with two counts of murder for the death of her daughters.
