Police are set to interview a disqualified learner mini-bus driver who was involved in the crash which killed a toddler yesterday afternoon.
The tragic incident in Kemps Creek saw a mini-bus carrying nine people and a Mercedes Benz commercial van collide on Mamre Road just after 1.30pm.
The two vehicles are believed to have collided in the northbound lanes.
A two-year-old girl sustained critical injuries in the crash and later died in The Children's Hospital, Westmead.
A 59-year-old man in the front passenger seat of the mini-bus was also critically injured, while a 23-year-old woman sitting in the middle row suffered two broken legs.
They are both being treated in Liverpool Hospital.
A boy and girl, both 16-years-old, are also being treated at the same hospital.
A 10-year-old girl, a nine-month old boy and a three-year-old boy were taken to the Children's Hospital.
The 20-year-old disqualified learner driver who was driving the mini-bus is being treated for abrasions.
According to NSW Police, it is believed that the people travelling in the van were all a part of the same family.
