The boy was handed a two-month minimum term on Thursday after being found guilty in May of attacking the girl over a two-hour period on a mattress in the house's living room.
Both offender and victim cannot be identified for legal reasons.
Following the bail decision, the victim's father criticised the minimum term and called for the suppression on the boy's identity to be lifted.
"Two months in jail equals one month for each hour that he raped and choked our daughter," the father told AAP on Friday.
"When you look at the damage he did to our daughter, the sentence is blatantly too short. The justice system is not treating rapists in the tough way the public wants them too.
"Given his total lack of contrition ... our family want the justice system to publicly name him. The public have a right to know his name."
The boy was charged in 2021, tried this year and found guilty of six counts of sexual assault and one count of intentional choking. He was acquitted of other charges.
The magistrate on Thursday said the most serious sexual assaults, involving penile penetration, must result in youth detention.
While he'd shown no contrition, she deemed his rehabilitation prospects as "strong" based on character references and his family and social ties.
His full term runs nine months, with a one-year probation period for some sexual assaults and the choking offences also hanging over his head.
The court was told the girl didn't like the boy but was heavily affected by alcohol when she agreed to some consensual activity and then pushed him away.
She has described the boy as a "monster" who'd left her "ashamed and irreversibly damaged" and struggling with nightmares, psychological issues and low self-esteem.
"He violated me and he took away my virginity," she said through her lawyer Michael Bradley on Thursday.
"He took away my confidence, my mental health and the healthy life I led before the attack."
The boy's appeal will be heard at a later date.
