An expansion to the definition of murder in Queensland will is set to be introduced, with parents and carers who cause fatal injuries to their children as a result of abuse to face life in prison.

Attorney-General Yvette D'Ath announced an expansion of the definition of murder on Wednesday while also endorsing recommendations to amend sentencing laws for child homicide.

It would bring Queensland into line with other jurisdictions and follows widespread community outrage over recent child killings.

Under the changes judges can still impose a sentence that considers individual circumstances of each case while acknowledging community expectations that killers should spend more time behind bars.

It comes after a review of child homicide rulings in Queensland courts found prison sentences handed to child killers are too low.

Ms D'Ath said she would introduce the law changes as soon as possible when state parliament resumes next year.
