Ian Everitt Atkinson, 63, was most recently jailed for offences including possessing more than 45,000 child exploitation images, and was previously imprisoned for sexually abusing two girls, aged seven and eight.
Jonathon Neal Lewis, 32, was most recently jailed for the online grooming of a 14-year-old girl.
Under WA’s dangerous sex offender laws, the court can keep predators locked up beyond their prison sentence, or free them with very strict conditions.
In separate applications, the state applied for both men to stay behind bars, but WA Supreme Court Justice Joseph McGrath instead imposed five-year community supervision orders in each case.
In Atkinson’s case, Justice McGrath imposed 49 conditions, including electronic monitoring and a curfew.
“I am satisfied to a high degree of probability that Mr Atkinson currently presents an unacceptable risk to the community that he would commit a serious offence,” Justice McGrath said in his judgment.
“(But) there are conditions that may be imposed under a supervision order that will provide adequate protection of the community.”
For Lewis, Justice McGrath imposed 52 similar conditions.
“I do not accept the state submission that Mr Lewis should be incarcerated for another two years to undertake treatment when that treatment may be completed in the community while the ongoing risk is managed by a supervision order,” Justice McGrath said in his judgment.
“The protection of the community may be properly and satisfactorily advanced by a supervision order, rather than a continuing detention order.”
