Applications for bail in all courts are governed by the Bail Act 1985 (SA) which applies to South Australian and Commonwealth offences.
A bail agreement is an undertaking to the Crown to attend all court proceedings (except when excused from attendance by the court) and to comply with all conditions [see Bail Act 1985 (SA) s 6].
The bail agreement and guarantees end upon finalisation of the matter for which bail was granted, [see Bail Act 1985 (SA) s 20] or if revoked by the court as a consequence of breaching a term or condition of the bail agreement [see Bail Act 1985 (SA) ss 6(4), 6(5) and 18(1)].
