Hayne, 32, was being cross-examined on the fifth day of a trial in Newcastle District Court on Monday over two counts of aggravated sexual intercourse without consent recklessly inflicting actual bodily harm. He has pleaded not guilty.

It comes after a woman - who cannot be named - accused Hayne of assaulting her using his finger and mouth at Fletcher on the night of the 2018 NRL Grand Final. The woman was left bleeding from her vagina.

Hayne says the encounter was consensual and the injury was caused by an accidental clip from his fingernail.

During cross-examination on Monday, Crown prosecutor Brian Costello took Hayne through his evidence from Friday, pointing out the former Eels fullback could not recall several details when questioned.

Hayne agreed he could not remember the photos he had sent the woman on social media, whether he ate or went to his accommodation first after arriving in Newcastle for a buck's party on grand final weekend, the names of the venues he visited during a pub crawl or making two late night phone calls to the woman that same weekend.

Mr Costello asked why Hayne's memory improved when it came to recounting how he had organised to visit the woman on the night of the alleged incident.

"Are you just making all that up?" Mr Costello asked.

"No, because I was going to Sydney so I was getting ready for a long trip," Hayne replied.

Mr Costello also asked Hayne why - given he made "a bit of a point" in the witness box of describing his near-signing with the Sydney Roosters and his affiliation with two of players participating in the grand final - he left the buck's party halfway through the game.

Hayne said he needed to return to Sydney.

Mr Costello said: "You weren't in such a rush you went straight to Sydney", putting it to Hayne that he went to see the woman "with the expectation of having sex".

He repeatedly asked why Hayne left the party when he did, with Hayne saying several times he did not understand the question.

Earlier during cross-examination, Hayne agreed that he had invited the woman to join him during the 2018 buck's party but she refused - instead suggesting they could meet for coffee or breakfast and telling him he was welcome to invite a friend.

Mr Costello put it to Hayne that the woman had knocked back his invitation on the Saturday - Hayne agreed - as well as one on the Sunday.

Hayne said he could not remember but "might have" invited her the second time.

He suggested to Hayne that the woman was "cautious" about meeting with the NRL star, but Hayne said she refused the invitation because he was at a buck's party.

Hayne agreed that the issue of the woman's consent to sexual activity was "up in the air" when he was in a taxi on the way to meet her the night of the alleged assault.

When Mr Costello put it to Hayne that messages from the woman in the days and weeks prior were a "promising sign" she may consent to sexual activity but that they did not constitute consent itself, Hayne agreed.

The court heard that Hayne did not believe there were "mixed signals" the night of the alleged incident, saying he would have ceased the sexual activity if the woman told him do do so, but "she never said no".

The trial continues.
