A Muslim man who left his wife to die for five days after he said he found her tied up and badly injured in their home has been jailed for at least eight years.

Mohamed Naddaf pleaded guilty to the criminally negligent manslaughter of Ashlee Brown, 25, who died in their 'unkempt and dirty' Craigieburn home in Melbourne's north in November 2016.

Justice John Champion said Ms Brown was found in the passenger seat of the couple's car after having been subjected to a 'deliberate and frenzied assault' and tied up with clothesline wire.

The mother of three children under five had been bashed, stabbed, gagged and had her long strawberry blonde hair cut off.

Ashlee Brown suffered more than 100 blunt and sharp force injuries. The mother of three children under five had been bound, gagged and had her long strawberry blonde hair cut off

Naddaf helped Ms Brown to the bathroom, putting her down on a flannelette sheet on the floor, and fed her water through a syringe for five days.

He finally called triple zero on November 6 after Ms Brown died from complications arising from more than 100 injuries including internal and external bleeding.

Right-wing activist group, the Australian Liberty Alliance, staged a protest outside the Victorian Supreme Court, condemning what Ms Brown's mother Siobhann believed was an 'Islamic honour killing'.

Justice Champion said he did not accept Naddaf's claim that Ashlee asked him not to call for help in case their three children were taken by authorities.

'All that was required was a phone call,' Justice Champion said. 'Her death was slow, avoidable and miserable.'

Justice Champion said Naddaf's motivation was unclear. The court heard Naddaf had a significant criminal history and was a long-term drug user, taking heroin, marijuana and ice.

'The Crown is not in a position to prove who inflicted the injuries upon Ms Brown,' Justice Champion said.

'It is not possible to say exactly when Ms Brown died but... she suffered to a considerable degree.'

Siobhan Brown told reporters after the sentencing she believed Naddaf should have instead faced a murder trial for the death of her daughter, who had converted to Islam and had not spoken to her for five years.

'I am here today to raise awareness to the horrific, torturous death that Ashlee endured,' Ms Brown said outside court.

'My daughter's injuries and circumstances surrounding her death had all the hallmarks of an Islamic honour killing.'

Naddaf was sentenced to 11 years' imprisonment and must serve at least eight years before being eligible for parole. He has already served 621 days in pre-sentence detention.

Ms Brown told Daily Mail Australia last week she had had not heard from her eldest daughter since a phone call five years before she died.

Her daughter told her she was marrying a Muslim man and was three months pregnant with her first child.

Ms Brown had met Naddaf when Ashlee visited the family's home in country Victoria when she was about 18.

Ashlee was a fun-loving girl,' Siobhann Brown told Daily Mail Australia. 'She was giving. She was loving. She loved the sun, the beach. She loved singing, dancing, having fun'

'She introduced him as "Macca",' Ms Brown said. 'It was very brief.

'He seemed like a nice, very polite, young man. It pains me to say that. I didn't see him again after that.'

HOW DID ASHLEE BROWN DIE? Ashlee Brown was found dead on her bathroom floor at Craigieburn, in Melbourne's north, on November 6, 2016. Her husband Mohamed Naddaf, 37, told police he had found Ashlee bloodied and beaten in their garage four or five days earlier. Naddaf said he had 'cared' for Ashlee instead of calling an ambulance because she had asked him not to. A post-mortem examination found Ashlee had suffered more than 100 injuries to her head, torso, buttocks and limbs. She had been stabbed in the thighs and had bruising to her right side, including her breast. Naddaf was originally charged with assault and false imprisonment. He was later charged with killing his wife but pleaded guilty to manslaughter based on negligence. Naddaf is not accused of causing any physical harm to Ashlee. Advertisement

There was no communication for some time before a phone call came 'out of the blue' that would mean the end of all contact between Ms Brown and her daughter.

When Ashlee was about 20 she rang to say she was pregnant and wanted her mother's blessing to convert to Islam and marry Naddaf.

'She said to me, "Mum, I need your blessing to become Muslim". She said "I'm three months' pregnant and I'm engaged to Mohamed. I would really like to marry him, mum, and settle down and have a baby".

'I said to her, "Darling, I don't know anything about the Muslim religion. As long as you know what you're doing".

'I said, "Do you have to wear one of those burqas or hijabs?" I didn't know what they were called.

'She said, "No mum, only when I go into the mosque because it's disrespectful for a woman to show her face before God".

'I said to Ashlee, "As long as you're making a fully informed decision and it's what you really want".'

Ashlee said that it was.

'There was a pause after that,' Ms Brown said. 'She said. "Thank you, mum". And then her voice seemed to change and she said, "It's Islam". That didn't mean anything to me at the time.

'We said goodbye to each other and we hung up and I didn't hear from Ashlee again.'

Ms Brown said she was convinced the lack of subsequent contact with Ashlee was solely down to her religious conversion and Naddaf controlling his wife.

'I believe Islam killed my daughter,' the 46-year-old said.

'If I could have taken that phone call back I would have not have given her my blessing. I would have said "No, sorry love".

'I'm not against Muslims. That's not what it's about.

'I'm not telling Ashlee's story to make friends. I don't want to tell lies, I'm not going to sugar coat it. I'm telling Ashlee's story for it to be known.'

Ms Brown could not believe her daughter would willingly cease all contact with her mother and three siblings who are now aged 11 to 22.

Ms Brown also believed the legal system let her down.

'It was explained to me that they didn't have enough evidence to successfully convict him of murder,' she said of Naddaf's manslaughter plea.

'I feel let down. I feel there should have been a trial. Where was our fight? We didn't have one.

'The offence of murder needs to be redefined.'
