A Catholic brother who sexually abused nine "vulnerable and marginalised" boys at a Queensland orphanage has been sentenced to eight years behind bars for his historic crimes.
Brisbane District Court judge William Everson on Monday denounced Francis Brophy as "a cowardly, evil pedophile" who preyed on defenceless boys at the Scenic Rim region facility between 1978 and 1983.
He sentenced the 87-year-old, who was convicted of a total of 38 offences, to a head term of eight years behind bars but set a parole eligibility date in August 2019.
The jury retired to start deliberations on Friday, returning on Monday afternoon to convict him of a total of five offences, including three counts of indecent treatment and two of carnal knowledge.
However, he was also acquitted of one count of each charge.
It came after the trial heard Brophy's victim, who had wanted to learn guitar, was first abused in early 1982.
But during what was meant to be a private lesson in a shed at the BoysTown facility the years of mistreatment began, crown prosecutor Michael Lehane said.
"(Brophy) in essence sexually exploited (the boy) in a very grave way," he told the jury in his opening remarks.
