Victorian authorities are investigating the death of a 3-year-old who died of a cardiac arrest after being placed on hold by emergency staff for nearly two minutes.
The family of the child waited for one minute and 41 seconds, longer than the target time of five seconds, while on hold to triple-0, Australia's emergency number.
Ambulance Victoria said paramedics were dispatched "without delay" after being called to the cardiac arrest at 6.29pm on Monday.
Advanced Life Support crew first arrived on the scene at 6.43pm and loaded the girl in to take to the hospital.
However, the girl died while in their care.
