A former Liberal Party staffer did not seek medical treatment after she was allegedly raped in Canberra's Parliament House, but took a pregnancy test weeks later while working on the federal election campaign in Perth, a court has heard.

More of Brittany Higgins's police interviews were played to an ACT Supreme Court jury today on the second day of the trial of her alleged rapist, Bruce Lehrmann.

Mr Lehrmann, also a former Liberal staffer, is accused of raping his then colleague Ms Higgins after the pair had been out drinking in March 2019.

He has pleaded not guilty and denies he had sex with Ms Higgins.

In one taped interview from May 2021, played to the jury today, Ms Higgins told officers she took a pregnancy test because of the alleged assault but had not sought medical treatment.

When police asked her about a text she had sent to a former partner, telling him she had been to a GP, she explained the text was to placate him because he was worried about her and she had not visited a doctor.

However, she told officers she later visited a GP about her mental health problems related to the alleged assault.

When police asked her if she had taken the morning-after pill, Ms Higgins said she had not.

Ms Higgins also described the aftermath of the alleged rape, saying she was left feeling "trapped" and "not human".

She said that, after Mr Lehrmann allegedly finished sexually assaulting her, "he didn't say anything and he left the room".

"I do remember that he got up and he looked at me, and it was a strange moment of just … eye contact and, at that point, I didn't say anything to him anymore," she said.

Ms Higgins told police that, during the alleged incident, Mr Lehrmann "wasn't looking at me, he was looking over me".

She also said that when she became conscious, she thought Mr Lehrmann had already been penetrating her for some time.

"I was coming late to the party and it felt like me saying no … it was like this strange sort of afterthought," she said.

"He wasn't reactive to it. He was almost finishing so it wasn't acknowledged, he just kept going."

In the interviews, Ms Higgins said she cried during the alleged assault and told Mr Lehrmann "no".

The court heard that parliamentary security staff later woke her in the office of then Liberal minister Linda Reynolds, where she and Mr Lehrmann worked.

She said she ate a box of chocolates, vomited in the toilet in the minister's office and then left.

Ms Higgins said she next saw Mr Lehrmann several days later at work.

She said they did not discuss the alleged incident and he "did not seem ashamed" or "upset".

"He didn't really approach me, which I remembered and … I didn't really try and actively approach him for any work-related stuff," he told police.

"It was kind of like this weird stand-off. It wasn't really, like, adversarial," she said.
