Three men have been found guilty of raping a 'mate' with a bottle on Australia Day.

A Brisbane courtroom has erupted at the conviction of three men for the rape of an unconscious teenager with a glass bottle at an Australia Day party.

Family and friends wailed in disbelief as Bailey Hayes-Gordon, Jacob Watson and Nicholas Jackson were found guilty on Friday by a District Court jury of assaulting a 19-year-old friend in 2015.

Their trial had heard the men were heavily intoxicated when Jackson, 19, rolled the teenager over and restrained him by the feet.

Watson, 18, then filmed with his phone as Hayes-Gordon, 18, inserted the bottle.

The video was shared on Snapchat and Facebook, with Hayes-Gordon writing in a chat: “(The complainant) passed out so we stuck a bottle up his arse and he just took it … Funniest thing I’ve ever seen, legit.”

A fourth man, 21-year-old Frazer Eaton, was given a wholly suspended 18-month jail sentence in Februray after he pleaded guilty to holding the young man’s shoulders and spreading his buttocks during the incident.

Eaton testified against the the other men and denied he gave evidence in exchange for a lighter penalty.

After a week-long trial it took the jury only a few hours to find the three men guilty of rape.

Supporters in the public gallery broke down in sobs and cried out, including one woman who shouted: “I’m going to kill myself”.

Another woman called Eaton a “liar”, prompting Judge Anthony Rafter to warn people to remain quiet as the sentencing submissions were handed down.

Hayes-Gordon’s lawyer said it was “extremely unusual” for there to be a rape with no aspect of sexual gratification.

But Judge Rafter said that was cold comfort to the victim who had been penetrated by the bottle.

“It’s still a violation of the victim’s body,” Judge Rafter said.

Crown prosecutor Caroline Marco had argued Hayes-Gordon was the principal offender in the rape but all three men had shown no remorse or co-operation.

The men have been remanded in custody with Judge Rafter expected to hand down the sentences on Friday afternoon.
