Four Pakistani brothers, who had emigrated to Australia, were jailed for between 10 and 22 years on Thursday for the gang rape of two teenaged girls in Sydney.
The court heard the men repeatedly raped two girls aged 16 and 17 at knifepoint at the brothers' family home in Sydney in July 2002.
The girlfriend of one of the brothers told the court she had been told by one of the accused that they raped the girls "just for fun".
The brothers, aged between 17 and 25, migrated to Sydney at different times from 2000 and during their trial claimed they knew nothing of the Australian justice system.
They cannot be identified because the two youngest brothers were under-18 at the time of the crime.
Sentencing judge Brian Sully rejected the men's claim that police had framed them because they were Muslims, saying cultural differences were no excuse for sexual assault.
"Neither the law nor the culture of Australia recognises multiculturalism, providing in any way or to anybody a convenient justification either for rape or for any other form of sexual abuse," Sully said.
Prosecutors presented DNA evidence, mobile phone records and other incriminating evidence against the brothers.
Two, aged 25 and 17, were jailed for 22 years, third aged 23 received a 16-year sentence and another aged 19 received 10 years.
A fifth man aged 25, not related to the brothers, committed suicide in police custody last week while awaiting sentencing over the same attack.
