Major Collision Investigation Unit detectives are appealing for dashcam footage following a single rollover which killed two children in Parwan earlier this week.
Emergency services were called to the intersection of Nerowie and Parwan-Exford roads just before 4pm on 8 September.
A female driver and seven children were inside the eight-seater 4WD, which rolled and came to a stop on grass between the road and a paddock.
Paramedics worked on a seven-year-old girl, but she sadly died at the scene.
An 11-year-old boy was airlifted to hospital with critical injuries where he later died.
Five other children were taken to hospital with non-life-threatening injuries.
The driver, a 34-year-old woman, was taken to hospital for observation.
Investigators are appealing for any motorists that have dashcam footage and travelled along Nerowie Road between 4-4.30pm to come forward, regardless of whether or not they witnessed the crash.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit an online confidential report at www.crimestoppersvic.com.au.
