He said the man took every opportunity to be alone with his daughter.
"You offended against her in the most violent way, which no society, let alone a civilised society, would tolerate."
Judge McDonald said the man befriended the other girls through his daughter and who were asked to stay at his house.
He said the man would get himself in positions such as fishing trips with the sole purpose of abusing them.
One of the victims addressed the court on the effect of his offending on her.
Judge McDonald fixed a starting point for sentence at 18-and-a-half years and gave the man a discount for his pleas and remorse.
He said the pleas meant the victims didn't have to relive the trauma of giving evidence during a trial and be cross-examined by the defence.
The offences were "grossly serious" and the courts had to dish out a sentence that deterred people from behaving in a similar way and to denounce the offending, he said. The judge acknowledged the strength shown by one of the victims who spoke in court.
If the man's daughter had not requested name suppression for her father, Judge McDonald said he would not have granted it.
He sentenced the man to 14 years and nine months in prison and imposed a minimum non-parole period of seven years and four months.
The man sat in the dock motionless during sentencing while his family in the public gallery sobbed, particularly as the facts of his offending were read out.
Judge McDonald highlighted only part of the facts before saying the man offended on a weekly basis.
Arthur Fairley represented the man while Nicole Dore appeared for the Crown.
