Samuel Jade Lincoln Jingle has been sentenced to life in prison, with a minimum of 19 years, for the murder of Ms Murray in the Kimberley town of Fitzroy Crossing.
Jingle, 37, subjected Ms Murray to years of physical abuse before stabbing and strangling the 32-year-old First Nations woman in December 2024.
On Tuesday the WA Supreme Court was told Jingle stabbed the mother of three children 14 times.
Ms Murray's aunt had tried to stop Jingle, but couldn't because of his size and strength, and called for other men to intervene.
The ABC reports Justice Michael Gething described the attack as "impulsive and unsophisticated", saying Jingle had a "high level of anger".
The court heard Jingle had been drinking heavily and using methylamphetamine, and that Ms Murray was physically smaller and vulnerable.
The ABC reports the court was told Jingle and Ms Murray had been in an on-again, off-again relationship for 10 years, and that Jingle had committed violence against her before and served terms of imprisonment for some offences.
Jingle pleaded guilty to murder and his minimum sentence of 19 years was backdated to December 2024, when he was first taken into custody.
Ms Murray's brother, Gavin Smith, told media outside the Supreme Court the family was satisfied with the sentence, but were still grieving.
He said he wanted people to remember his sister as a loving person.
"Loving, kind and respectful person, happy-go-lucky lady, my little sister," he said.
"I'm hoping we don't experience this kind of behaviour in the Kimberley anymore, with violence and all this stuff happening on a regular basis."
Mr Smith said he believed action could have been taken sooner over Jingle's "abusive behaviours".
