Immigration Minister Peter Dutton has refused to intervene in the case of Iranian asylum seeker Mojgan Shamsalipoor.

Ms Shamsalipoor's case has galvanised the community at Brisbane's Yeronga State High School, which has mounted a year-long campaign to get her out of immigration detention.

"Our school community most certainly will not give up the fight for Mojgan to be free," deputy principal Jessica Walker told Australian Story.

"We've been involved in actively campaigning for over a year now and we won't be stopping."

Ms Shamsalipoor fled Iran after enduring rape and domestic violence at the hands of family members.

She had also been forced to become the child bride of a 60-year-old man.

Her mother scraped together funds to send her to Australia, under the protection of her older brother.

Ms Shamsalipoor was 18 when she arrived on Christmas Island in 2012.

She applied for refugee status and while it was processed she was allowed out into community detention in Brisbane.

It was in Brisbane that she met her future husband, Iranian refugee Milad Jafari, at a youth camp.

Mr Jafari and his family had been granted refugee status and he was attending Yeronga State High School.

"Milad came to see me and said, 'Miss I've got this friend, can she come to our high school?'" Ms Walker recalled.

"When I met Mojgan I felt she'd be a really good fit for our school. I could see she was very committed to education."

Brought to school with a guard, sometimes searched

Soon afterwards Ms Shamsalipoor and Mr Jafari moved in together and after two years they married.

School friend Eden Boyd remembered that they were very open about their relationship at school.

"I remember her talking about being engaged in drama class and she was showing us her ring and was so happy," she said.

When the Department of Immigration found Ms Shamsalipoor did not qualify as a refugee, she was taken back into detention at the Brisbane Immigration Transit Accommodation.

Yeronga State High teachers negotiated for her to continue her schooling by way of day release.

"So each day, in Year 12, she was brought to school with a guard on a bus and sometimes she was searched when she came into school," Ms Walker said.

Despite these hurdles, Ms Shamsalipoor continued to perform well and planned to study midwifery.

In August last year, she was forcibly moved from BITA to Darwin's Wickham Point Detention Centre as a result of the Federal Government's decision to place rejected Iranian asylum seekers back into detention if they did not voluntarily return to Iran.

This action galvanised teachers, students and parents from Yeronga State High to organise protests and rallies in support of Ms Shamsalipoor.

"It was very shocking because she wasn't that far away from graduating, and when the news came it was kind of hard to comprehend," school friend Amber Moko said.

'She did not talk about her rape'

Ms Shamsalipoor's supporters ranged from a legion of schoolgirls to politicians who raised the case in state and federal parliaments.

Darwin-based lawyer Kevin Kadirgamar came on board and he took the view there was a case for ministerial intervention.

"When I read the decision refusing her protection visa, what was clear was that there were things left out in her story," he said.

"She did not talk about her rape or sexual abuse. We then went about formulating a submission explaining to the minister what a compelling and compassionate case this was."

Meanwhile, Ms Shamsalipoor continued her studies despite the difficult conditions in the Wickham Point Detention Centre. She completed Year 12 and graduated in absentia, leaving her husband to collect her certificate.

He would try to visit Ms Shamsalipoor in Darwin every couple of months.

"There is a guard in the corner, sitting, watching us. The first thing they said, 'you cannot hug inside the facility, you cannot touch each other that much, you cannot kiss'," Mr Jafari said.

"I hugged her and I wasn't allowed but I just tried to hug her very deeply and very hard and the guard was saying, 'that's it, that's it' and I couldn't stop hugging her."

Not giving up yet

In May this year, Wickham Point was marked for closure and Ms Shamsalipoor was returned to Brisbane.

Her husband tried to meet her at the airport, clutching a bunch of red roses. Ms Shamsalipoor appeared in the corridor before being whisked away.

Mr Jafari and his Brisbane supporters try to visit Ms Shamsalipoor as often as possible.

Visits must be booked in advance and the visiting times are often changed with little or no notice. There is a single public phone.

Last week, Ms Shamsalipoor heard that the Minister for Immigration had declined to reconsider her case.

A spokesman for Mr Dutton told Australian Story that "her claims were thoroughly assessed" and that the decision "has been affirmed by the Refugee Review Tribunal and in a subsequent judicial review in the Federal Court".

"Once these legal options have been exhausted and the courts have ruled an individual is not owed protection, the person is expected to leave the country," the spokesman said.

But Mr Kadirgamar has not given up.

"On the legal side, no stone will be left unturned for Mojgan. Every legal avenue will be explored," he said.
