The impact dragged the Nissan for about 60 metres before it burst into flames, killing its driver, 21-year-old Shannon Lorenzo Juriansz, “almost instantly”, Senior Constable David Morris from the Major Collision Investigation Unit told the court.

Mr Currie’s Mazda 3 crossed over the centre median strip east into the oncoming traffic and travelled a further 50 minutes before stopping, according to the police's application to remand Mr Currie.

Jacinta Barnett, a rear seat passenger in the Mazda, was taken in a critical condition to The Alfred hospital, where she later died. An 18-year-old passenger remains in hospital in a critical but stable condition.

“The accused alighted from the vehicle and made a phone call to his father,” police said in their remand application.

“He did not call 000 or assist his friends in his vehicle or check on the welfare of the other driver.”

Under questioning by defence lawyer John Moore, Senior Constable Morris said witnesses overheard Mr Currie say on the phone: “I’ve T-boned another car and my car is f---ed.”

Mr Currie declined to make a comment when interviewed by police about 3.30pm on Wednesday, but admitted to being the driver, Senior Constable Morris said.

Police are still awaiting the results of a blood sample taken at the scene to determine whether Mr Currie had alcohol or drugs in his system, he said.

But police told the court that a reconstruction of the collision scene suggested that the teenager was travelling at speeds of between 120-130 km/h - or possibly higher - which police said was consistent with CCTV footage captured on Ferntree Gully Road and two other locations, and witness accounts.

“Dash-cam footage was seized from the vehicle and that shows the last recording of any data was the 25th [of September] - four days before the crash, but certainly there’s evidence on there of high speed driving,” Senior Constable Morris said.

“One of particular note is the vehicle being driven along the same stretch of the road at 177 km/h, dragging another car. A number of other incidents captured on that dash-cam suggests the accused has been driving at excessive speeds. There is evidence of burnouts in car parks.”

Senior Constable Morris conceded, under questioning by Mr Moore, that the dash-cam was not secured to the Mazda 3, but said Mr Currie admitted to the dash-cam belonging to him “before changing tack”.

“He did make comments about the dash-cam that it did belong to that [Mazda 3] car and he was the only one who drove that car,” Senior Constable Morris said.

“When there was incriminating evidence about the dash-cam, he changed tack … You can see the dash of the vehicle but we haven’t confirmed it is the same car.”

Mr Currie was living with his parents, 21-year-old sister and 14-year-old brother in Bayswater North before he moved out three weeks ago to live with friends in Glen Waverley.

As part of his bail conditions, he will move back in with his family, report to police three times a week and not drive a motor vehicle.

Mr Currie was expressionless as he watched on, only to say “I do, Your Honour” when asked by Magistrate John Doherty if he understood his bail conditions.
