Luke Andrew Lazarus, 23, is being sentenced in Sydney's Downing Centre District Court having last month been convicted of the attack on the 18-year-old woman behind Soho on Victoria Street, Potts Point, in May 2013.

Lazarus' father, Andrew Lazarus, is a part-owner of the club, as well as popular Bondi Junction hotel The Eastern.

The sexual assault occurred in an alleyway behind the club after Lazarus told the woman, who was on her first night out in Sydney, he would take her to a VIP area.

In court on Thursday, a victim's impact statement was read out on behalf of the woman, who said she would never be the person she was before the attack.

"I thought that once I left the alleyway the pain would go away ... but it didn't," the woman's statement said.

"Everything that made me who I was stayed in that alleyway."

The woman said she spent days sitting in a bath after the attack and, in the two years since, had cried until she "couldn't breathe, crying until I physically couldn't any more".

"I'll never be who I was. I had to rebuild myself with what I had left," she said in the statement.

"A part of me died that day, the part that trusted others."

During the trial it was heard that Lazarus approached his victim on the club's dance floor.

He claimed to be a part-owner of the club and asked if she wanted to meet the DJ.

Lazarus then told her: "No, we will go to a VIP area" before he took her out of a back exit into an alleyway.

The pair kissed but the woman said she wanted to go back to her friends because she was uneasy being in an alleyway.

He told her to put her hands up against the fence before demanding that she "just get on your hands and knees and arch your back".

The woman, fearful of what he would do if she did not comply, then knelt on the gravel and put her hands on the ground.

Lazarus then sexually assaulted the woman for 10 minutes during which time his victim told him she was a virgin.

When he had finished, he told her to put her name into his phone.

After the attack, the woman returned to the club, met her friends and left.

Police were informed the following morning after the woman told her older sister what had occurred. Detectives seized CCTV footage from Soho, which showed Lazarus leading the woman out into an alleyway.

They also intercepted calls on his mobile with nightclub staff during which he talks about having sex in the back alleyway.

In a text message to his friend the afternoon after the attack, Lazarus also said: "I honestly have zero recollection of calling you ... Was a sick night – took a chick's virginity."

His friend replied: "bahahahaha nice popping does cherries ..."

Lazarus replied: "... it's a pretty gross story tell ya later".

The note section of his phone also contained a list of female names, with his victim's name appearing on the end of the list.

During the trial before Judge Sarah Huggett at the Downing Centre District Court last month, Lazarus' lawyers argued that the sex was consensual. But a jury convicted Lazarus of one count of sexual intercourse without consent.

The hearing continues.
