Nirmeen Noufl, 55, pleaded guilty to the lesser charge of manslaughter just as her Supreme Court murder trial was due to begin last month.
The plea was accepted by prosecutors on the basis that it was a case of excessive self-defence.
According to the agreed facts in the case, Noufl told psychiatrists an argument became physical one night in May 2023, during which she was assaulted and tried to get away.
Mr Noufl's remains were placed in garbage bags and dumped in rubbish bins with the help of the witness, who cannot be identified for legal reasons.
Justice Peter Hamill today handed Noufl a sentence of six years and three months, with a non-parole period of three years.
Because Noufl has been in custody since her arrest, she will be eligible for parole in October next year.
The judge said the minimum term would ensure Noufl had a period of supervision, if released, to re-integrate.
Justice Hamill said he was not satisfied beyond reasonable doubt that the offender intended to kill the victim, but that her conduct in disposing of her husband's remains was a "disturbing" feature of the case.
The court documents say Mr Noufl had met another woman during a 2022 trip to Egypt, where they owned property, and had told his wife he planned to marry the other woman.
