A 42-year-old woman has died after being allegedly stabbed by her partner in the remote Northern Territory town of Lajamanu on Monday.
A 46-year-old man has been arrested and is expected to be charged later this week, NT police have said.
It's believed the woman was stabbed with an edged weapon.
A NT Police spokesperson said a large crowd had gathered around a local clinic where the critically injured woman had been taken at about 6.20pm on Monday.
Not long after police attended the scene, the woman was declared dead, the spokesperson said.
In the aftermath, the 46-year-old man was allegedly assaulted by unknown community members.
He was arrested nearby after suffering non-life-threatening injuries and remains in custody.
NT Police say two crime scenes have been declared, and Major Crime detectives have taken over the investigation.
On Tuesday, NT News reported NT Police Assistant Commissioner Travis Wurst said the woman's long-term relationship would form part of the investigation, as well as a report for the coroner.
It is the seventh alleged domestic violence-related homicide in the Top End since the beginning of July, whilst further two women remain in critical condition from alleged domestic violence attacks.
All the women are Indigenous.
"The Northern Territory cannot accept one death, let alone seven matters being investigated in this manner," Mr Wurst said.
"Not only is Northern Territory Police investigating those seven matters, but we have two other matters that have occurred in that same time frame where both the victims of serious assaults remain in the ICU at Royal Darwin Hospital undergoing intensive treatment.
"That is effectively nine matters where death has occurred or possibly could occur since July 1."
He said the tragedy only continued to mount.
"We wonder why we have young people on our streets who are committing crime and terrorising the community at times…part of that has to be linked back to domestic violence," Mr Wurst said.
He said everyone needs "to do better".
"Northern Territory Police need to do better. The community needs to do better."
The NT has the worst domestic violence rates in the country, with intimate partner homicides seven times higher than the national average.
Last week, a sistagirl (a term used by Aboriginal and Torres Strait Islander people to describe gender-diverse people that have a female spirit and take on female roles in the community) was stabbed to death at her home in an alleged domestic violence killing in Darwin.
A 34-year-old man, believed to be related to the victim, was arrested at the scene.
Earlier this month, a man was charged with the domestic violence-related murder of his 22-year-old partner in Katherine.
The 36-year-old man was also charged with aggravated assault for a separate historic incident against the same woman.
Her 57-year-old partner Desmond Frankie Booth was charged with murdering the 43-year-old woman, as well as breaching a domestic violence order.
