An Australind woman accused of stabbing and killing her de facto partner during a heated argument has been found not guilty of murder but guilty of manslaughter.

Rachael Elizabeth Boyd, 29, had pleaded not guilty to the murder of Trent Panizza, 29, at their Leschenault Parade home on January 28.

Boyd claimed Mr Panizza - from the well-known Panizza football family - stepped into the 15cm blade knife which she picked up to ward him off during a heated argument.

But the prosecution asked jurors to apply "commonsense" to the claim and argued Boyd had picked up the knife, intending to injure Mr Panizza during a momentary lapse of self control.

Justice Stephen Hall told jurors this morning they would have to consider whether Boyd meant to injure her de facto when she picked up a knife during an escalating argument over domestic matters, including Mr Panizza's drinking, his refusal to go with her to her parents' home and his smoking inside.

Justice Hall explained that determining Boyd's intention at the moment of picking up the knife was key to whether she could be convicted of murder.

"Did she stab him deliberately," Justice Hall asked.

Jurors were asked consider whether Boyd acted with gross negligence when she picked up a knife during a heated argument.

During the four-day trial much has rested on the Boyd's police interview where, deeply distressed, she tells detectives Darren Clifton and Mark Tweedale how she "just held the knife up at him".

"He'd already hit me down on the floor, he was saying I should calm down, he stepped into it.

"He's just pushing my buttons, so he's got an excuse to misbehave."

Boyd is expected to be convicted this afternoon.
