A Supreme Court jury was expected to retire on Tuesday to consider its verdict in the trial of Kevin Willcocks for sexual intercourse without consent.

Mr Willcocks was cross-examined after a week of evidence given about the buck's night party at which the alleged assault happened in the Darwin rural area in 2017.

He is accused of penetrating the woman with his beer bottle during a dildo show she had been hired to perform.

He does not deny the act but has pleaded not guilty to the charge, which involves acting with knowledge of or being reckless to a lack of consent.

Mr Willcocks told the prosecutor in cross-examination that he had not heard the woman lay out any "rules" before the performance but did accept that there were "boundaries", that he said could shift.

Asked if he thought the woman had to specify a rule that no one should put a beer bottle into her vagina, he answered: "no".

"Do you accept that a bottle being placed in her vagina is one of those boundaries?" the prosecutor asked. Mr Willcocks replied: "I've seen worse things [in strip shows at] the Winnellie Hotel."

Before that the prosecutor had asked if the woman was a "plaything", to which Mr Willcocks said: "well she was that night, she was playing with the boys".

He added: "I didn't lie down and rape her if that's what you mean."

Mr Willcocks told the court that he does not recall how the beer bottle came to be in the woman's vagina but thinks he must have approached her "being a larrikin" and inserted it.

He said he was taken aback by the woman's reaction, which was different to what he had expected it to be, so he removed the bottle and apologised to her.

He said that it had not been his intention "to hurt anyone, it's not in my nature".

Inappropriateness of conduct 'not the point': defence

In his closing address, Mr Willcocks's defence lawyer said there were inconsistencies in the woman's evidence and two witnesses for the prosecution had contradicted parts of her version of events.

He said while there was no question the woman was distressed before leaving the party it was not clear whether that was because of the alleged incident or because she could not find her phone.

And he said prosecutors had not proved the elements of the charge.

"This matter brims with reasonable doubt," the defence lawyer said.

"Where is the evidence in the Crown case that demonstrates that Mr Willcocks knew at the time … that she was not consenting?

"Where is the evidence in terms of recklessness in that regard?"

He said the context of the situation was "absolutely vital", involving "a stripper, at a buck's party, who is in the business of firing dildos out of her vagina".

He said it was beside the point of the legal question whether the jury thought what Mr Willcocks did was appropriate or poor conduct.

He said character witnesses testified that Mr Willcocks was "a family man, who is a hard worker, and an honest man who has a good reputation in the community".
