GRAPHIC CONTENT WARNING: This story includes graphic detail of sexual assaults.
A 52-year-old man found guilty of 11 sex crimes against children has been described as 'predatory'.
Crown prosecutor Jody Dennison said the man's crimes were not opportunistic, but the result of the man's efforts to actively create opportunities to be alone with the children.
On Wednesday, the man was found guilty of three counts of maintaining a sexual relationship with a young person, six counts of indecent assault and two counts of rape.
The offences were committed against six children from three North-West families between 2012 and 2018.
Throughout the two week trial, Mr Dennison said it was the state's case the man gained access to the children through friendships with the three families.
Two of the families were neighbours of the man and the third family lived in his house for about six months in 2014, though no offending during that time was alleged.
Mr Dennison said the man used the friendships to abuse the children, and the abuse only stopped when police became involved and not voluntarily.
The man was first charged with offences against two of the complainants in 2017 and was bailed, but has been in custody since being arrested and charged with the remaining offences in December 2018.
Mr Dennison said the man committed offences against children who were as young as nine-years-old at the time of offending.
He said one of the complainants was subject to years of sustained abuse from age 11 which started with grooming, progressed to masturbation and anal penetration which the child was forced to reciprocate on the offender.
Mr Dennison said by finding the man guilty the jury had also accepted the Crown's case the man sought to ejaculate on his victims.
"Anal penetration by the penis is a demeaning and degrading form of sexual abuse," Mr Dennison said.
"Ejaculating or seeking to ejaculate on a child is equally degrading or demeaning."

Mr Dennison also said the man's lack of relevant prior convictions should not be taken into account, as that allowed him access to the children.
"He has breached the children's trust, he has breached the trust of the parents," Mr Dennison said.
Defence lawyer Donal Craig told the court the man was sexually abused as a child, and his lack of prior convictions for sexual matters should be considered.
He also referred to the witnesses which gave evidence of the man's otherwise good character and work ethic.
The man will be sentenced Wednesday, August 14.
