Prosecutors are now pushing for Jake Elias Versteeg, a Canberra labourer, to be sentenced to a term of full-time imprisonment.

Versteeg was set to stand trial in the ACT Supreme Court last month, but he instead pleaded guilty to rape and committing an act of indecency without consent.

While he eventually admitted committing the crimes, there was a dispute on the facts of the case.

The court previously heard Versteeg went on a burlesque-themed cruise to Vanuatu with his mother, who is one of Australia's top burlesque performers.

On the ship, he met and developed an infatuation with the dancer who would become his victim.

In an incident at Versteeg's Canberra home in June 2018, he and the victim initially engaged in consensual kissing and touching.

The victim said Versteeg then held her down despite her protests, before raping her for between one and three minutes.

But Versteeg, described by his barrister Margaret Jones as "a lovesick puppy", claimed to have only sexually penetrated the victim "a bit" and for no more than one second in a momentary loss of self-control.

On Wednesday, Justice John Burns rejected Versteeg's version of events.

The judge said he could not determine beyond reasonable doubt how long the rape had lasted.

However, he was satisfied that it went on for longer than Versteeg claimed and that it only ended when the victim bit Versteeg on the shoulder.

Justice Burns also found Versteeg's penetration of the victim had been deeper than the labourer had said.

The judge found it telling that in Facebook messages a short time after the incident, Versteeg did not challenge the victim's assertions that he had held her down and sexually penetrated her after she had said "no".

In the messages, Versteeg accused the victim of overreacting to the incident.

He said in the messages that he "wasn't listening at all" when the victim said no and that it was "like being plugged into a game".

The victim had earlier sent Versteeg messages in which she told him to stop blaming her for not being more clear when she had said no "a thousand times".

"You tried every trick in the book to manipulate me into doing what you wanted," the victim said in one message.

Crown prosecutor Rebecca Christensen on Wednesday urged Justice Burns to lock Versteeg up, saying full-time imprisonment was the only appropriate sentence.

But Justice Burns said he needed to consider the possibility of sentencing Versteeg to an intensive correction order, which is a jail sentence served in the community rather than behind bars.

He ordered a pre-sentence report and an intensive correction order assessment ahead of the case returning to court on September 11.

Versteeg will remain on bail until that date.
