State attorney-general Vanessa Goodwin will meet with the chair of the Sentencing Advisory Council Arie Freiberg this week to discuss the abolition of suspended sentences.
Ms Goodwin said that phasing out of suspended sentences was a key Liberal election commitment and that she intended on progressing to consultation with the community and key stakeholders.
"The Liberal Government will work closely with the Sentencing Advisory Council and other key stakeholders to develop alternatives to suspended sentences that will genuinely reflect the gravity of crimes committed," she said.
Ms Goodwin said the government would also be addressing the former goverment's "soft stance" on sex offenders.
"They were happy to release sex offenders from jail without treatment," he said.
"The Liberal Government will ensure that every sex offender who goes to jail must receive treatment."
Ms Goodwin will also push legislation for minimum mandatory sentencing for people convicted of serious sexual offences against children.
