The truck driver, a 65-year-old man from Newcastle was also uninjured. Both drivers were taken to Goulburn Base Hospital for mandatory testing.

Patrick Vidler was in a stable condition in Goulburn Base Hospital on Thursday.

Christian's father, Sydney man Gary Vidler said the news of his son's death had come as an "awful shock."

"Parents should not be burying their children," he said.

He described Christian as lovable and loyal man who'd had a challenging life but deeply loved his mother, who looked after his four children following his partner's passing.

He was born in Sydney, educated at Saint Greg's, Campbelltown, but left in Year 8.

Christian was on his way to Sydney at the time to deal with personal business. Mr Vidler said police had informed him that fatigue was likely a factor in the crash.

He is also survived by his twin sister Belinda and four children aged eight, 11, 13 and 15.

His funeral will be held at Campbelltown and burial at Camden on a date to be announced.

Police will prepare a report for the Coroner.
