A teenager charged with dangerous driving over a crash near Sydney that claimed five lives had his licence suspended twice for speeding, a court has heard. 

Tyrell Edwards was last night interviewed by police over the crash at Buxton, involving a Nissan Navara ute which collided with a tree.

Three girls and two boys, aged between 14 and 16, died, and Mr Edwards suffered non-life threatening injuries.

One of the victims was Year 9 Picton High School student Lily Van de Putte.

The ABC has received permission from Lily's father, John Van de Putte, to identify her but the other victims cannot be named for legal reasons.

Mr Edwards, 18, has been charged with five counts of dangerous driving occasioning death and was today refused bail.

Picton Local Court heard Mr Edwards has only had a provisional licence since 2021, and in that time he was suspended for two separate three-month periods over incidents of speeding.

The prosecutor told the court the Crown's case is strong and footage exists which supports "elements" leading up to the alleged offences.

The footage depicts "a high level of moral culpability", the court heard.

The court was also told the prosecution has concerns Mr Edwards, who comes from the small community of Bargo, is likely to come into contact with parties that have involvement in the proceedings and there is a risk he could interfere with witnesses.

His lawyer proposed conditions including that he live with his parents, report to police daily and abide by a curfew.

But Magistrate Mark Douglass said Mr Edwards's driving suspensions stood out.

"As a direct result of his driving inexperience, he was subjected to two demerit point suspensions," he said.

His licence was renewed in July this year and the magistrate said the driving history was "problematic" for the bail application.

He took into account that Mr Edwards has previously experienced anxiety and requires psychological treatment following the crash.

"However, given the egregious breach of trust, given the blatant breach of road rules that police allege occurred, this court has no confidence that this particular person would comply, given the history I've explained, with any bail conditions the court set at this particular point in time," he said.

"He was suspended for two three-month periods in perhaps less than 18 months.

"That was not enough, according to police, to stop what is a very serious course of dangerous driving, if proven."

Mr Edwards, who the court heard has no criminal history, appeared via audio-visual link wearing a dark hoodie and held his hands clasped together on a table in front of him.

A large group of supporters attended court, including his mother and father.

The case will return in November.

Earlier today, Premier Dominic Perrottet expressed his condolences to the families of the victims.

He said his government would do everything it could to help the community through this "horrendous tragedy".

"On behalf of everyone in NSW, we wrap our arms around you," he said.

All of the victims attended Picton High School and yesterday Mr Perrottet visited the campus.

"Obviously it's a very difficult time but I know they will get through.

"The government's allocated significant support and counselling to the teachers and students.

"It's through times like this that our state is at its best, it comes together, and I saw that yesterday in the community out in Picton."
