Australian woman Sara Connor says she was bitten by the Bali police officer whom she is accused of killing, her lawyer says.

After more than three hours of being interrogated at Denpasar Police Station on Monday, the strain on Ms Connor was obvious, with the mother of two looking exhausted.

Her lawyer Erwin Siregar conceded there were many questions that remain unanswered.

The story she has so far given, he said, was "a little different" to that aired in the media by her British boyfriend David Taylor's legal team.

According to Mr Siregar, Ms Connor has told police that she and Mr Taylor had gone to the beach on Tuesday night.

While there, she lost her purse.

"She saw a man and she asked him by shaking his body, 'Where is my purse?'" Mr Siregar told reporters.

"At that time the victim (police officer Wayan Sudarsa) was lying face down on the beach ... Sara from behind asked 'Where is my purse?'."

Mr Siregar said Ms Connor did not realise Mr Sudarsa was a police officer as she couldn't see any of the badges on his uniform and only noticed the man was wearing a beige shirt.

When asked about bite marks Ms Connor had received on her hand and thigh, Mr Siregar said the police officer "bit her".

Sometime after this confrontation Ms Connor and Mr Taylor returned to their room at Kubu Kauh Beach Inn around 1.30am, showered and went out to buy cigarettes, before going back to the hotel and falling asleep.

"She woke up at 7.30am as was Sara's habit in Australia," Mr Siregar added.

He said no rape had taken place and the pair left Kubu Kauh Beach Inn on Wednesday, as they had always planned to.

It wasn't until the following day that an alert to immigration officials went out seeking Ms Connor and Mr Taylor for questioning over Mr Sudarsa's death.

His bloodied body was discovered at around 3.30am local time with 42 cuts, bruises and scratches across his face, head and hands.

A broken beer bottle was found nearby. Blood found at the crime scene is "identical" to that discovered at the Kubu Kauh Beach Inn in Kuta where the pair were staying, police allege.

According to Mr Taylor's lawyer Haposan Sihombing, his British client has alleged Ms Connor complained to him that she had been attacked by a "bad cop" at Kuta Beach on the night Mr Sudarsa was found dead.

"She told him that she was pushed and he lay on top of her on the sand," Mr Sihombing told AAP on Sunday.

"She screamed and there were some people helping her. And then the police officer left."

It is not clear as yet who this "bad cop" allegedly was.

Mr Sihombing said Mr Taylor would "tell the whole truth" on Monday. Interrogations of the pair are expected to continue into Monday evening.

Meanwhile, Ms Connor's ex-husband and father of her two children - Anthony 'Twig' Connor - said he will speak to the media on behalf of her family at a press conference in Sydney on Wednesday morning.
