(1) the respondent requires supported accommodation;
(2) without significant daily support in supported accommodation in the first six months of release, and ongoing support beyond that time, which could only be funded through the National Disability Insurance Scheme (NDIS), there was an unacceptable risk that the respondent could not cope with the pressures of living in the community, would become non-compliant with his medication, may resort to substance use, and be at a high risk of committing a serious sexual offence; and
(3) the respondent requires ongoing treatment for his delusional disorder.[3]

The clear intention of the review process is to allow for the possibility of a change of circumstances. Detention under the DSO Act is not a punishment for a past offending: it is a protective mechanism designed to prevent the risk of future serious sexual offending from being realised. If circumstances change such that the risk of reoffending reduces or can be adequately managed in the community, then the continuing need for detention must be considered...It does not follow from this that a court conducting an annual review is bound by the factual findings made at previous hearings. In practice, however, there is usually little prospect that expert evidence on a review will call into question the previous finding that the respondent was a serious danger to the community...
It is a significant thing to deprive a person of his liberty, not for something he has done but for something that he might do in the future. In order to justify detention on these grounds the evidence must be acceptable and cogent and establish the existence of a serious danger to the community to a high degree of probability: s 7(2) DSO Act. Such a finding requires satisfaction that there is an unacceptable risk that the person would commit a serious sexual offence if not placed under a supervision order or detained.
The risk of reoffending may change over time. It may be affected by age, health, or the successful completion of treatment. The availability of new technology or resources in the community may also affect whether the risk of reoffending can be managed by a supervision order. There is also the possibility that the risk may increase because of a failure of treatment or a relapse into deviant thinking.
The justification for making a continuing detention order is the existence of an unacceptable risk of serious sexual offending that cannot be adequately controlled by conditional release. However, detention also serves the purpose of allowing treatment and care in a secure environment: s 17 DSO Act. This confirms an obligation on the part of prison authorities to facilitate change by offering programmes and access to counselling.
If the risk changes or resources improve to enable more efficacious conditions then the need for detention may dissipate. In these circumstances, continuing detention may be unjust.
The review process is intended to ensure that detention only continues where necessary. It mitigates the otherwise draconian effect of imprisoning people for crimes that they have not committed. Reviews are not, therefore, a mere welfare check: they are an exercise of judicial power to affirm, vary or rescind a detention order. Continuing detention should not be ordered unless that course is justified by the circumstances existing at the time of the review. The court should choose the order that is least invasive of the person's right to be at liberty, whilst ensuring an adequate degree of protection of the community...[5]
Matters to be considered pursuant to s 7(3) HRSO Act Antecedents and criminal history
Reports prepared under s 74 for the hearing of the application and the extent to which the offender cooperated in the examination required by that section
Any other medical, psychiatric, psychological or other assessment relating to the offender
Propensity to commit serious offences in the future and whether or not there is any pattern of offending behaviour
Any efforts by the respondent to address the cause or causes of the offending behaviour, including whether the respondent has participated in any rehabilitation program, and whether the participation in any rehabilitation program has had a positive effect on the offender
The risk that, if the offender were not subject to a restriction order, the offender would commit a serious offence and the need to protect members of the community from that risk
Is the respondent a high risk serious offender? Is there an unacceptable risk that the respondent will commit a serious offence?
Is it necessary to make a restriction order to ensure adequate community protection against the unacceptable risk that the respondent will commit a serious offence?
Continuing detention order or supervision order?
In choosing between an indefinite detention order or a supervision order, the fact that the paramount consideration is the need to ensure the adequate protection of the community does not exclude other considerations. The use of the word 'adequate' indicates that a qualitative assessment is required. In considering whether a supervision order would adequately protect the community, account must be taken of conditions which can be placed on a supervision order so as to ensure the adequate protection of the community, the rehabilitation of the respondent and his care and treatment. The Act does not require that there be no risk of reoffending. Such a requirement could never be met and would mean no person to whom the Act applies would ever be released. The question is whether the risk is reduced to a reasonably acceptable level that ensures adequate protection of the community. That requires a weighing of the nature and degree of risk in the context of methods for the management and reduction of that risk. If, after considering all the evidence, the court is left in doubt as to whether the conditions of a supervision order would adequately protect the community, because the paramount consideration is the need to ensure the adequate protection of the community, the court must expressly decline to rescind the continuing detention order.[105]
Has the respondent satisfied the court on the balance of probabilities that he will substantially comply with the standard conditions?
