Supreme Court of WA

Original judgment source is linked above.
(1) If the court hearing a restriction order application finds that the offender is a high risk serious offender, the court must -
(a) make a continuing detention order in relation to the offender; or
(b) except as provided in section 29, make a supervision order in relation to the offender.
(2) In deciding whether to make an order under subsection (1)(a) or (b), the paramount consideration is to be the need to ensure adequate protection of the community.
An offender is a high risk serious offender if the court dealing with an application under this Act finds that it is satisfied, by acceptable and cogent evidence and to a high degree of probability, that it is necessary to make a restriction order in relation to the offender to ensure adequate protection of the community against an unacceptable risk that the offender will commit a serious offence.
Whether or not a risk that an offender will commit a 'serious offence' is 'unacceptable' is a question which requires the court's judgment as to the nature and extent of the possible harm. The assessment of the nature and extent of the possible harm directs attention to the possible serious offences that might be committed and the harm they may cause. It also directs attention to the likelihood that the offender might commit such offences (that is, the likelihood the risk might eventuate). The extent to which deterrent factors have operated to reduce risk in the past feeds into the assessment of current and future risk, as does the offender's historical and current response to rehabilitation. These are all factors that inform the assessment of whether the risk is 'unacceptable'. They are by no means exhaustive. I am reluctant to attempt to provide greater definition, bearing in mind the caution expressed by the High Court in M v M against 'striving for a greater degree of definition than the subject is capable of yielding'.
If the risk is found to be 'unacceptable', the nature and extent of that unacceptable risk then informs the assessment of whether a restriction order is necessary to ensure adequate protection of the community. And, as Kiefel CJ, Keane and Steward JJ explained, the assessment of whether the order is necessary requires recognition that an offender's entitlement to be at liberty is not lightly to be denied.
(footnote omitted)
The court should make the order that is least invasive of the respondent's right to liberty, while at the same time ensuring an adequate degree of protection of the community, having regard to the paramount consideration stipulated in s 48(2). As was decided in respect of s 17(2) of the [Dangerous Sexual Offenders] Act, that requirement does not exclude other considerations. Further, the use of the word 'adequate' indicates that a qualitative assessment is required. It cannot simply be assumed that the most assured preventative measure is detention and, therefore, the protection of the community will always favour such an order.
(footnotes omitted)
(a) to ensure adequate protection of the community; or
(b) for the rehabilitation, care or treatment of the offender; or
(c) to ensure adequate protection of victims of serious offences committed by the offender.
The question of whether the respondent will substantially comply with the standard conditions of the supervision order requires consideration of all of the circumstances, both personal to him and external, which will affect him. External circumstances include the conditions of the supervision order, the available means to monitor, supervise and treat him, and any pro-social support available to him.
The requirement of appropriateness [in s 27(1)] imposes a duty on the Court to make only the additional supervision conditions required to ensure 'adequate' protection of the community, while imposing the minimum intrusion on an offender's liberty.

The offending occurred on 23 February 2017. The victim, Ms Button, was aged 38. [Mr Yamalulu] had been in a relationship with Ms Button for about three or four years. They had one child who was aged three at the time of the offence.
When the offending occurred, the relationship between Ms Button and [Mr Yamalulu] had ended. There had been a history of domestic violence. A violence restraining order was in force at the time of the offence for the protection of Ms Button. The order prohibited [Mr Yamalulu] from contacting her or being within 50 m of her.
On 23 February 2017, between 8.00 pm and 9.20 pm, Ms Button was at a house in the Mindi Rardi Community at Fitzroy Crossing. She was with [Mr Yamalulu's] brother. [Mr Yamalulu] had been drinking heavily and was intoxicated. He returned to the house and found Ms Button having sex with his brother. The brother ran from the house.
[Mr Yamalulu] violently assaulted Ms Button. He grabbed her, twisted her arm and threw her to the ground. When Ms Button was on the ground, [Mr Yamalulu] jumped repeatedly onto her chest, legs and head. He then walked outside and sat down. Other people heard Ms Button screaming and pleading with [Mr Yamalulu] to stop attacking her.
[Mr Yamalulu] did not render first aid or seek any medical assistance for Ms Button. He fled when he saw a police car arriving at the house. [Mr Yamalulu] was arrested the following day. He had attempted to hide from the police and, initially, gave the police a false name.
After the police found Ms Button unconscious in the backyard of the house, she was taken to the Fitzroy Crossing Regional Hospital. Medical practitioners sedated and intubated her. Ms Button was then flown to Royal Perth Hospital. Initially, she was cared for in the intensive care unit. Later, she was treated in the trauma unit and the internal medicine unit.
Ms Button suffered very serious injuries including a broken right mandible, a subdural haematoma, cervical and thoracic spinal injuries, significant bruising and contusions, strangulation bruising around her neck, broken ribs and a broken clavicle. The most serious injury suffered by Ms Button was the subdural haematoma. This has resulted in quadriplegia.
[Mr Yamalulu] committed a frenzied, savage and relentless attack upon a vulnerable, unarmed and defenceless woman. He inflicted shocking injuries. [Mr Yamalulu] ignored Ms Button's repeated pleas for him to stop attacking her. He showed no mercy. Ms Button is permanently disabled and has an exceptionally high level of impairment. Her prospects of improvement are limited.
On or about 8 July 2023 [Mr Yamalulu] and the victim, RB, had been in a relationship for about three months. [Mr Yamalulu], who was intoxicated, jealously questioned RB about some recent travel on her part. She ran away and he chased and caught her. He took off her shirt, leaving her in her bra, and then punched her in the head and her upper back, about seven times. At some point, he also stabbed her in the right rib cage with an unknown implement. She screamed for help. Afterwards, it hurt her to breathe and she had a cut on her nose and a sore head. It was only later she realised she was bleeding from her chest, and [Mr Yamalulu] told her he had stabbed her. The next day, [Mr Yamalulu] made RB walk across the road, where he punched her again in the back. He made her help him look for his phone. When she found it, she messaged her mother for help. When he saw the message, he smashed the phone. RB was later found to have a punctured lung and a lacerated scalp.
(footnote omitted)
... [Mr Yamalulu] has been convicted of a number of relevant violent and other offences, namely three offences of aggravated unlawful wounding (2014, 2015, 2023), two offences of aggravated assault occasioning bodily harm (2008, 2023), and one offence each of aggravated common assault (2011), assault occasioning bodily harm (2010) and assaulting a public officer (2012).
The most likely scenario of a serious offence under the HRSO is an assault on his intimate partner. [Mr Yamalulu] may misinterpret her behaviour as 'cheating' even in a social situation when she engages in a conversation with another male. There is also a possibility of infidelity on both parts, which would lead to an argument which is likely to escalate to significant violence specially when alcohol is involved. His risk is likely to escalate if there is a threat of the relationship breakdown. He may escalate to violence with a weapon, resulting in serious physical harm, including death of the victim and any person who attempts to intervene in the situation.
Another scenario may include the community members including police. He would easily be influenced by his peers and engage in violent behaviours as a means of conflict resolution or to meet his demands. The violence will be instrumental to achieve compliance. The likelihood of [Mr Yamalulu] assaulting a public officer or a member of the community is considered to be chronic.
If [Mr Yamalulu] reengages in criminal activity, it has the potential to occur frequently. His risk is chronic and is directly related to his inability to resolve interpersonal conflict, an entrenched substance misuse habit and antisocial lifestyle.
His offending behaviour has been maintained by difficulties with emotional and behavioural regulation especially the expression and/or inhibition of angry or aggressive impulses, willingness to use weapons, the presence of antisocial personality traits and cognitions, procriminal/proviolent attitudes, values and beliefs, substance misuse, history of family dysfunction, trauma and abuse and the long term effects of complex trauma including over-arousal, affect regulation difficulties, impulse control issues, aggression, self-destructive and risk taking behaviours and distorted beliefs about [one's] safety and the trustworthiness of others, impaired judgment, an aggressive response to threat and poor consequential thinking.
It will be important for [Mr Yamalulu] to have access to intervention, counselling and support that targets intimate partner violence and relationship issues as well as alcohol and drug use. Without access to counselling, interventions and support his ability to succeed in the community and lead an offence free life will be compromised.
... absence of employment, financial stress, unstable lifestyle, limited prosocial supports, limited meaningful engagement in community based hobbies or leisure pursuits, and reliance/dependence on welfare have all contributed to Mr Yamalulu's risk of reoffending in the past.
... I said to him it will be six months, it's going to be really challenging. He seemed to understand what the requirements were and was still committed to that.
Community Supervision Assessment Report by Ms Hartland dated 4 September 2025

...
The South Hedland facility is situated approximately three kilometres from the nearest Adult Community Corrections Centre, and approximately three kilometres from the South Hedland Police Station which functions 24 hours, seven days a week. Urinalysis testing is available at the Hedland Health Campus which is also approximately three kilometres away and can be facilitated Monday to Friday from 10am - 1pm.
Treatment options report of Ms Cashmore dated 21 August 2025
Neuropsychological reports of Dr Vuletich dated 20 September 2017 and 5 October 2018
Mr Yamalulu displayed some insight into his offending by acknowledging the connection between his alcohol misuse issues and anger management issues within intimate relationships to his offending. He was able to suggest strategies of distancing himself from family or peers who insist on consuming alcohol and to walking away from future relationship arguments if he is unable to communicate in a calm manner.
