"The seats were not certified and did not contain any seatbelts for the rear passengers to utilise."
Having left Queenstown, the group in the van socialised for some time before some went to sleep.
Upon reaching Winton, Collinson stopped the van for a short time before continuing his journey south on State Highway 6.
At approximately 4.30am, he left the Winton boundary where he drove past a slippery when wet sign warning drivers that for the next 2km the road could be slippery and had a temporary 50km/h limit.
At the time, the road was damp and Collinson was driving at 100km/h.
A short distance out of the town boundary, Collinson steered left around a bend and the vehicle, at this point, drifted towards the left side of the road, crossing the fog line and driving into the water table ditch on the side of the road.
At the same time as the vehicle did this, it collided with the 50km/h temporary zone sign. It was estimated at that time that he was driving between 96 and 108km/h.
The van rotated sideways and rolled approximately six times over a distance of about 49 metres into a paddock.
The passenger's siding door came off, flying into the air and hitting the power lines immediately above the crash scene.
"As the van was rolling all occupants who were unrestrained in the rear of the van were thrown from it at different points as it was rolling," the summary of facts said.
Miss Newport was thrown from the van and her body became trapped under the vehicle on the driver's side. She died at the scene.
Seven other people sustained a number of injuries, ranging from moderate to serious.
Collinson told police the back of the van went into the opposite lane of the road and, as he saw a pole in front of him, he tried to avoid it before the van crashed.
He was not affected by alcohol or drugs.
The court heard reparation of $12,000 was being sought for the damage of the van.
Defence counsel Richard Smith told the court all victims were friends and he would seek in his submissions a disqualification, reparations and supervision sentencing for Collinson.
Community Magistrate Simon Heale remanded Collinson at large until sentencing on November 12.
