60 The appellant points out that, when he later turned to consider the question of indefinite imprisonment, his Honour concluded that the offender's condition was treatable and that treatment required an extended custody-based biological and psychological treatment programme, together with compulsory post-release treatment and monitoring (at [58]). It is submitted that his Honour's apparent finding, at that point, that compulsory post-release treatment was necessary in order to ensure protection of the community, was not consistent with his conclusion in relation to parole. However, it is to be noted that, in discussing the question of the necessary duration of custodial treatment, his Honour referred, at [55], to the five years of custodial treatment which Dr Srna thought was necessary and the one to three years' treatment in custody estimated by the psychologist, Mr Merriman. (I would add that the psychologist, Ms Zuin, considered that he needed individual psychological treatment, apparently in custody, for "at least" two to three years, followed by possibly a group programme, again apparently in custody.)
