Onur Dedeoglu was taking the then 17-year-old home after she'd been drinking to celebrate finishing trial Year 12 exams in August 2018.

He dropped two of her male friends off and then deactivated his Uber for a window of 18 minutes, at the end of which she woke to find him on top of her in the back seat.

A jury earlier this year accepted the victim's evidence that Dedeoglu, 39, said "it's OK" after she tried to push him off, realising he was kissing her and digitally penetrating her.

He was found guilty of two counts of indecent assault and one of sexual intercourse without consent.

Judge Nicole Norman today called the offending "out of character and opportunistic".

"Although approaching adulthood, the victim was still a child who was entitled to safety," she told the Downing Centre District Court.

"The offender took advantage of her vulnerability."

Dedeoglu claimed the girl gave consent and insisted he thought she was "in her 20s", however the judge said CCTV showed all three passengers looked young.

She sentenced Dedeoglu to eight and a half years in jail with a minimum of six years, accepting offences of this kind can have long-term psychological impacts.

In a victim impact statement the girl, who can't be named for legal reasons, said she felt violated, distraught and confused.

She said she now sees the world "through a different lens", where she "questions men's intentions more than I should have to".

"Finishing high school was meant to be one of the most enjoyable periods of my teenage years," she said.

"I'll have to live with the memory of that trauma for the rest of my life."

The court heard Dedeoglu's wife and young son have returned to Turkey and he had no family left in Australia.

He will be eligible for parole in April 2025.
