It is not in dispute that you have an established diagnosis of schizophrenia and that you have been significantly methamphetamine-dependent for the past two to three years. You have also used heroin. Methamphetamine, combined with the absence of antipsychotic medication, has contributed to a significant decline in the stability of your mental health. You have a history of increased sexual pre-occupation whilst using methamphetamine. Dr Deacon opined that:
Methamphetamine appears to have generated the onset of an obsessive fetish-type sexual drive whereby he became motivated to access and often wear female underwear. Also, and more alarming, has been a history of intense sexual fantasies, experienced as imaginary sexual scripts, including the odd notion of finding a female stranger in a house during a burglary, leading to a fanciful consensual and non-coercive sexual interaction.
...
Dr Deacon concluded that you were obviously mentally unwell at the time you offended, mostly due to the impact of methamphetamine, combined with your non-compliance with antipsychotic medication. Dr Deacon states:
His altered mental state was mostly attributable to methamphetamine, but he was also in the grips of a psychotic process. The elevated sexual pre-occupation was the primary driver to the offending but the onset of auditory hallucinations further reinforced the compulsion to offend. He was not so impaired to not be able to understand the wrongfulness of his actions. His capacity to exercise reasonable judgment during the offending period was likely to have been significantly compromised. Notably he was immediately aware that he'd committed a serious crime after raping the victim. His unstable mental condition should be considered to have reduced his moral culpability of the offending conduct to at least a mild extent.
It is not in dispute that you should be considered more vulnerable in gaol than a prisoner of normal mental health. Dr Deacon indicates that you have already felt quite vulnerable amongst mainstream prisoners and that you could foreseeably be targeted whilst serving a sentence. I accept that you are likely to experience prison as more onerous given your mental illness and that prison may impact on your mental health although, currently, this Court was told that you are managing satisfactorily.
The question of whether your unstable mental condition should be assessed as reducing your moral culpability has been extensively canvassed during the course of submissions. I am far from persuaded that this contention has been established. In my view, it is significant that your offending on 29 April 2014 displayed a considerable measure of premeditation and, further, that upon being interviewed by police, you acknowledged that your use of ice and failure to take your antipsychotic medication, was the trigger for your sexual fantasies.
You have shown over two decades that you can be law abiding when taking prescribed medication. Your offending is a product of abusing methamphetamine which you preferred to your prescribed treatment. You well knew that your use of methamphetamine was intimately connected to your aberrant sexual conduct and caused dis-inhibition. Nonetheless you persisted to abuse that drug despite residential treatment and awareness of its effect upon you. Your aberrant conduct was the subject of a record of interview with police on 27 March 2014. Yet within 23 days of that interview you broke into houses and stole women's underwear and 10 days later you raped [K].
I am not persuaded, on the balance of probabilities, that your underlying mental illness lessens your moral culpability. Further, even if this Court were to find that your moral culpability was lessened as a consequence of your mental illness, in my view, other countervailing sentencing considerations, including protection of the community, would prevail.[13]
