Section 4 states that a court cannot, at the point of sentencing, set a default period of imprisonment for non-payment of the offender levy. When a fine and an offender levy are imposed together, any payment made will first discharge the levy. If an offender defaults on paying a fine and is imprisoned, or given a supervised activity order, the court may remit such part of the levy which remains outstanding. Where an offender has been given a determinate sentence of imprisonment or detention (which is not suspended) and has made payments towards discharging the levy through deductions from earnings whilst in prison, any outstanding levy amount will be discharged by statute on the full expiry of their sentence i.e. when they are no longer eligible for recall to custody for deductions from prison earnings to recommence.
