A Queensland man whose "systematic and persistent" torture of a defenceless newborn led to her death has been jailed for nine years after pleading guilty to manslaughter.

Baby Paige was only 31 days old when she died from blunt force trauma in September 2012 after suffering almost a lifetime of "gratuitous" violence at the hands of her mother's partner Michael John Humphreys.

There weren't many parts of the baby's body that weren't injured, Justice David Boddice said.

There weren't many parts of Paige's body that weren't injured, Justice David Boddice said on Friday.

The Brisbane Supreme Court heard she had endured repeated blows to the back of her head, a blunt object had been forced into her mouth like a finger or pacifier, her limbs had been either twisted or shaken and a handprint-shaped bruise was found on her spine.
