Four men have now been arrested for the sexual assault, which happened in May of this year.
The harrowing footage showed up to eight men in the room with the girl, some of who were married with children, and was taken on a GoPro device.
Most of the men were in their mid twenties, and they attacked a very young ‘and very slight-framed girl.’
Detective Chief Inspector peter Yeomans sid: ‘These adult males are quite large men - and some of these men are married with children.’
Police believe the girl was either unconscious or semiconscious at the time of the attack, which she did not report, though the police have now made contact with her.
The girl is now undergoing counselling for the horrifying incident, which is now being investigated.
Tristan Carlyle-Watson, who filmed the rape, had his previous convictions - which included stalking and intimidation - read out in court.
Police in Sydney have urged anyone with information on this or any other sexual assaults to come forward to Crime Stoppers on 1800 333 000.
