Three men involved in the rape of a teenage friend with a glass bottle at an Australia Day party in 2015 will spend six months in jail.

Bailey Joseph Hayes-Gordon, Nicholas William Jackson, and Jacob Michael Watson — all aged 21 — pleaded not guilty on the opening day of their trial in the Brisbane District Court on Monday, but a jury was convinced otherwise and convicted the trio on Friday.

The court was told the victim became intoxicated and passed out in a downstairs bedroom after which he was rolled over. Hayes-Gordon then sexually assaulted him with the bottle while Jackson held his feet.

Watson filmed the incident.

The sexual assault of the 18-year-old was filmed and later posted on social media.

The trio appeared shocked when the jury read out the guilty verdict and sat with their head in their hands crying, while family and friends cried out in the court room.

Judge Anthony Rafter SC threatened to remove them from the courtroom and extra security was then brought in.

"The verdicts can't have come as any surprise to anyone who has seen the evidence in this case," Judge Rafter said.

'No sexual gratification in the rape'

The men were sentenced to two years in jail, which is to be suspended after six months.

In sentencing, Judge Rafter said none of the men were appalled or disgusted at what had taken place and in social media conversations the next day it was clear they all considered the incident was "somewhat amusing" but it was not "some sort of harmless prank".

Prosecutor Caroline Marco said the trio betrayed the trust of their friend and made degrading comments about the incident online.

"They should have realised when they were sober the gravity of the recording and not posted the material online," Ms Marco said.

Judge Rafter acknowledged all three had apologised to the victim prior to a committal hearing, there was no sexual gratification element to the offence and they all had good prospects of rehabilitation.

But he said: "The offence has had a significant impact on the victim."

Hayes-Gordon, Jackson and Watson were all handed two years in jail, suspended after six months.

A co-accused, Frazer John Eaton, pleaded guilty for his role in the rape in February and was sentenced to 18 months in jail, wholly suspended.
