A jury found Trevor Dunmall, 58, guilty of multiple charges, including two counts of sexually penetrating a person under the age of 12.
The court heard that the crime began in 2015 and continued for a period of two years; the Cranbourne man’s victims only emerged in the years following the abuse.
Dunmall has always maintained his innocence and forced his young victims to undergo a lengthy cross-examination.
Despite this, Judge Felicity Hampel reduced his sentence for suffering from ill health, including type 2 diabetes.
“Imprisonment in a time of COVID is more severe and as a result a sentence should be reduced,” Hampel told the County Court today.
“There is also the fear of being exposed to COVID in an environment where you no longer have control over who you see and when you see them.”
Hampel sentenced Dunmall to eight years and six months in prison, with a non-parole period of five years and six months.
In 2020, the former security guard was interviewed on 9News after he was smashed into a random attack on Cranbourne Park shopping center.
He will remain on the sex offender registry for the rest of his life.
