The case confirms that sentences of 14-15 years' imprisonment are within the appropriate range for high-level suppliers of kilogram quantities of high-purity methylamphetamine in Western Australia. Disparities of 6-7 years between sentences of principals and middle men in drug supply operations are justifiable where the principals' culpability is at the very high end of the scale. Hardship to an offender's family, including a spouse's serious medical condition, plays a lesser mitigating role in serious drug offences where general deterrence is the predominant sentencing consideration.
