Her clothes and the sleeping bag were discarded in one location, while her naked body was dumped in another.

Evans appeared in the Townsville Supreme Court on Wednesday where he was sentenced to nine years' jail for Ms Lapham's manslaughter in 2010.

The court heard the 30-year-old mother became annoyed at Evans on April 19 of that year, after she arrived home to see an empty bacon packet and knife in the kitchen sink.

She came towards her partner with the two items, before swinging the knife in his direction and knocking the beer bottle out of his hand.

A fight ensued and the pair struggled until they fell on one of the beds.

Evans then proceeded to punch Ms Lapham repeatedly in the head.

Justice David North said the fight could only be described as a "brutal bashing" over something as trivial as a bacon packet.

"You took your time after you beat her senseless, then gathered her body and disposed of her naked, depriving her of the opportunity of a funeral and a burial," he said.

Justice North recalled how Evans had told a psychologist he felt Ms Lapham's "skull give way" when he punched her.

However, he also found Evans was remorseful and accepted blame for what happened.

He would usually be eligible for parole after he had served 50 per cent of his sentence, but Justice North said he deserved some credit for taking police to where he dumped her body.

As a result, he said Evans would be eligible for parole after he had served four years.
