In the Australian legal system, a good behaviour bond is a type of non-custodial sentence which involves the condition of the offender's "good behaviour" for a set period.[1] The condition of "good behaviour" primarily requires the offender to obey the law, but may also include additional probation officer supervision, mandatory medical treatment or participation in rehabilitation, counselling and intervention programs.[2] These imposed conditions are determined by state legislation and at the magistrate's discretion.[2] A good behaviour bond may be established with or without a recorded legal conviction for the offence.[3] The specific conditions which constitute a good behaviour bond, as well as the consequences for breaching them, vary under each Australian state or territory's legislation, but overall are used most commonly for first-time and juvenile offenders.[3]
