A day after Jody Gore was sensationally released from her murder sentence in an act of mercy by the WA Government, she said she hopes her case brings the "silent epidemic" of domestic violence out into the open.

Ms Gore was sentenced to 12 years in prison for stabbing her abusive former partner to death in Kununurra during a drunken argument in June 2015.

She was released on Thursday just four years into a life sentence, with the State Government recommending the remainder of that term be remitted.

Ms Gore touched down in Broome in Western Australia's Kimberley earlier on Friday.

She told the ABC she was enjoying her freedom, but was still getting over the shock of her surprise release.

"It feels so good, great, wonderful to be back home on my country, walking on the land in the Kimberly," she said.

"It's my country and my people, my family and friends.

"They couldn't believe it, they thought they saw a ghost.

"[There were] hugs and tears — tears of happiness."

Ms Gore was planning to attend to medical appointments on Friday afternoon and spend the next few days in Broome before returning to her home town of Kununurra.

Gore case 'not a precedent'

WA Attorney-General John Quigley said the substantial history of domestic violence was a factor her early release.

But he said the case should not be regarded as a precedent.

During her trial, the court heard she was regularly physically assaulted and verbally abused by her husband, and she acted in self-defence when she stabbed him with a knife three times.

Ms Gore told the ABC she hoped her situation would help people understand domestic violence.

"[I hope it] opens the eye up on domestic violence — shed a light on that," she said.

"We have the alcohol and drug epidemic, but there's also domestic violence, [it's] serious.

"It's silent, but now it's out in the open."

Self defence not an offence: expert

Acting chief executive for The Women's Council for Domestic and Family Violence Services Kedy Kristal said women who acted in self defence should not be jailed.

"Women who are victims of horrendous domestic and family violence who then go on to kill their partner to basically save their own lives are not people who should be locked up," she said.

She argued any case where a woman killed a partner after sustained domestic violence needed scrutiny — because they may have acted in self defence.

"We've had the self defence law in for a number of years, it's not being used by judges in the way it's designed to be used," she said.

University of Western Australia's law school associate professor Stella Tarrant said if the law of self defence was applied and someone successfully raised self defence, then they had not committed an offence at all.

Professor Tarrant said jurisdictions around the country failed to adequately apply the law of self defence because there was a lack of understanding of what it was like to live in a violent relationship.

"We have a very deep assumption, and I think it's a very general assumption, that unless we're being being attacked at that moment, at that second, then we're not in danger," she said.

"The argument we make is that there are forms of entrapment that are not about only [being] trapped against a wall with a knife at one's throat in that instant.

"We know that because may women don't survive those forms of abuse — they actually die.

"We know that in those situations, it's very dangerous, and lives are at stake."

The West Australian government said it would amend its criminal code to better account for circumstances where domestic violence victims act in self-defence.
