The three-year-old died in March 2013 after suffering horrific injuries.

A court in Brisbane heard evidence from Williamson that he ignored proof his daughter was being sexually abused, reports AAP.

Williamson said didn’t take his daughter to a doctor despite her vomiting green for days, having obvious bruising on her face, and leaving blood in her nappies.

He told the court: “I didn’t think anything of it at the time.”

After hearing two days of evidence, Justice Roslyn Atkinson was expected to sentence Williamson but the case was adjourned until March 16 after his defence barrister requested a report into whether his client has a "psychological abnormality".

This week the court also heard evidence from Williamson's flatmate Christopher Kent, who said he witnessed the dad regularly abusing the three-year-old while he lived with the pair.

Kent, who spent 19 months behind bars after also pleading guilty to Kyhesha’s manslaughter, said Williamson also used a rope to lock his daughter in her squalid room for hours at a time.

He claimed the dad would tie one end of the rope to her door handle and the other to her bed.

Williamson’s defence team has argued Kent inflicted the fatal injuries.

Williamson allegedly locked his daughter in the bedroom while he slept during the day and would become enraged when she went to the toilet in her room.

In the weeks before the little girl’s death, Williamson punched her in the belly and would hold her arm as he smacked her, Kent told the court.

He said: “It was like two adults fighting. She cried and cried and cried – and all Matt could do was yell.”

"He'd smack her and slap her," Kent added.

He told the court Williamson was asleep on the couch on the day Kyhesha-Lee died when he noticed the child's lips were blue.

Kent claimed he attempted to wake Williamson to help.

But Kent said: “He didn’t give a s***. He just wanted his coffee and smoke.”

Kyhesha's mother, Danielle Joughin, who sat through confronting evidence in the Brisbane Supreme Court this week, says it is “hard to comprehend” the harrowing details that led to her daughter's death.

She told The Courier-Mail outside court yesterday: “It’s hard to comprehend ­really. No one helped her. It’s disgusting.”

On top of the horrific internal injuries, Khyesha also suffered bruises to her face, cuts to her ear and lip, and a stomach injury consistent with a punch or kick.

Williamson denies causing the injuries but Kent told the court he witnessed his former housemate regularly abusing the three-year-old while he lived with the pair.

Kent has previously been convicted of sexual assault and has a criminal record dating back to 1989, but denies ever abusing Khyesha.

He’s currently in jail, he says, for driving while disqualified and is worried fellow inmates will find out he’s giving evidence.

Several other witnesses, including former neighbours, were expected to give evidence at Williamson’s ongoing sentencing hearing.
