A man who raped his own daughter, forced her to wear bondage and pimped her to six other men told police it was fun while it lasted.
The father, who cannot be named, has been jailed for more than 22 years in what a judge described as one of the worst cases of its kind.
He pleaded guilty to 61 offences committed between 2013 and 2015 when the girl was aged between 11-13.
The graphic details of the 42-year-old's offending were revealed in the West Australian District Court on Thursday, including how he met the men through websites like Craigslist.
The abuse included giving the girl a stupefying drug, watching as others raped her and recording her while she was naked and in bondage.
In one incident, the girl was forced to wear a mask, gag and dog collar with the word "bitch" written on it.
As she struggled with the restraint, the girl pleaded with her father, saying: "Stop please, dad".
The girl was forced to shower with another man before being further abused.
The father told police he regretted his actions.
"I'm going to be honest, it was fun while it lasted but it went way over the line," he said.
In a letter to the court, the father expressed "remorse, regret and utter shame".
The father kept his head down and covered his face with his hand during proceedings.
He appeared to choke up and at times barely whispered his pleas of guilty when the charges were read out.
The father had originally faced more than 200 charges but 150 offences were combined into one and some others were dropped.
Prosecutor Justin Whalley said the girl, who lived with her father after her parents separated, looked to him for care and protection, but was instead subjected to "degradation of the highest order".
Mr Whalley said the group of offenders had been colloquially described as a pedophile ring and others in the community needed to be deterred from committing such depravity.
Judge Philip Eaton said the girl, who was now 14, had attitudes of loyalty to her father and trusted him to protect her and do her no harm.
"In fact, you were doing none of those things and you should have known so," Judge Eaton said.
"You in fact allowed complete strangers to treat your daughter as a sexual object and treated her like that yourself."
There would be lasting and probably irreparable consequences for the girl, he added.
The father was jailed for 22-and-a-half years and his earliest release date will be in October 2035.
Benjamin Simon Clarke was previously sentenced to three years in jail for his involvement, which included photographing the girl in lingerie and nude.
Former pastor and father-of-two, Dawid Volmer was sentenced to 10-and-a-half years after he admitted molesting and raping the blindfolded girl while her dad was present.
Four other men also face charges.
