Walking along a Brisbane city street, Laurent Rutabagisha and another man came across a heavily intoxicated woman in the early hours of the morning.
They told her they would call her an Uber.
Instead they carried the woman to the nearby City Botanic Gardens and took turns raping her.
When Rutabagisha and the man encountered the woman in September 2021 she was "basically unresponsive", the crown prosecutor told Brisbane District Court on Tuesday.
"You could see she was vulnerable," Judge Tony Moynihan said.
Pretending to help her, the two men held the woman under each arm and led her into the park.
When they reached a rotunda, they lay her on the ground.
"The complainant, due to her intoxication, was incapable of resisting you taking her to that location or the assault," Judge Moynihan said.
After about 40 minutes Rutabagisha and the other man left, only to return with her phone asking for her bank password, the crown prosecutor said.
She took the phone off them and walked away "as best she was able", the court heard.
A passer-by then helped the woman and she was taken to hospital.
Judge Moynihan acknowledged the woman's bravery after she attended court on Tuesday.
In a victim impact statement read in court, the woman said she still can't go near the Botanic Gardens after the "dehumanising sexual assault".
"After the assault I lost myself completely," it said.
The woman said she had since suffered seizures linked with complex PTSD and looked over her shoulder "everywhere I go".
She said she would never be the happy person she once was because of Rutabagisha's "inability to have human decency".
"I have listened carefully to the account ... speaking of the substantial and devastating harm that this offence has had ... and continues to have for her," Judge Moynihan said of the victim impact statement.
"I acknowledge her brave appearance here today."
When police arrested him days after the assault they found Rutabagisha with a small amount of cannabis and a pipe.
The defence barrister said Rutabagisha had shown shock and remorse at his behaviour and had co-operated with authorities.
Rutabagisha is at risk of deportation after arriving in Australia in 2015 as a 12-year-old refugee on a humanitarian visa.
A psychiatrist's report said Rutabagisha's history suggested a somewhat immature, impulsive adolescent prone to being easily influenced by others, reflecting his response to early bullying and alienation experiences.
It said Rutabagisha was a victim of child abuse and recent substance abuse problems, assessing him as a low risk for future sexual offending.
Rutabagisha, 20, on Tuesday pleaded guilty to charges including deprivation of liberty and three counts of rape.
He received an eight year jail term with 727 days spent in pre-sentence custody declared as time served.
