Northern Territory Police has been told it must take responsibility for "missed opportunities" in protecting a young Aboriginal woman from being killed by her violent partner.
Miss Yunupingu, 29, was fatally stabbed in the heart by her partner Neil Marika in October 2018 after suffering 13 years of "torture".
The week-long inquest into her death concluded on Friday in Darwin.
"There's a missed opportunity, and that must be owned by NT Police," counsel assisting the coroner Peggy Dwyer said in her closing remarks on Friday.
The inquest was told Detective Sergeant David Buganey did not accept Miss Yunupingu back onto a government domestic violence support program three weeks before she was killed in 2018, despite knowing she was a "high risk" of death or serious harm.
"That is extremely regrettable ... and sadly, Det Sgt Buganey conceded she should have been accepted onto the safety framework or at the very least, been reviewed," Dr Dwyer said.
NT Police Senior Sergeant Daniel Whitfield-Jones told the inquest he believed Ms Yunupingu would be in "good hands" when he referred her to Darwin, but there was a "lacklustre" response from Darwin police.
"(Darwin FSF) did one or two checks of a location and found she wasn't there, so she was removed," he said.
"Shortly after she was killed ... I was so f***ing angry.
"Next I was briefing (her father) to tell him his daughter had been killed, our organisation effectively allowed it to happen."
Dr Dwyer said while there were communication breakdowns within NT Police when assessing Miss Yunupingu's risk, the blame for her death does not lie with the organisation.
"I do have to make clear that we can't be certain that a referral to the Family Safety Framework at that time would have saved her, but what might have happened is that the police would have been more proactive in finding her and (arresting) Marika," Dr Dwyer said.
It was noted that the crisis accommodation centre in northeast Arnhem Land that flew Miss Yunupingu to Darwin to reunite with her violent husband also missed an opportunity to save her.
"It's inescapable that when Miss Yunupingu presented to the crisis accommodation, information about the risk that she was under should have been known ... it was available but wasn't properly investigated," Dr Dwyer said.
"All it would have taken is a phone call ... and they would have said that it was not appropriate for Miss Yunupingu to be transferred."
Marika was arrested and convicted of reckless manslaughter. He will be eligible for parole at the end of 2024.
NT Corrections worker Natalie Walker told the inquest that programs to rehabilitate Marika were "woefully inadequate" due to staffing levels.
“(The staffing) makes it extremely challenging for us to provide adequate rehabilitation,” she said.
“Doesn't make it impossible?” Dr Dwyer asked.
“It’s very challenging,” Ms Walker replied.
There are currently more than 2000 prisoners in the Northern Territory and only 18 staff members are able to deliver rehabilitation programs, Natalie Walker told the inquest.
Next week, the case of Kumanjayi Rubuntja will be examined by NT Coroner Elisabeth Armitage as the final part of Australia's biggest inquest into domestic violence.
Ms Rubuntja was a prominent Central Australian anti-domestic violence campaigner, murdered by her partner in January 2021.
