Somali asylum seeker, known as Abyan, claims she was raped and – as a result – made pregnant as she remains on the Nauru detention centre.
After thousands of people petitioned Immigration Minister Peter Dutton earlier this month, Abyan was flown to Australia for a termination.
But she was returned to Nauru days later, with the Department of Immigration and Border Protection saying she had changed her mind.
Abyan argues she never changed her mind.

Mr Dutton has now confirmed she will again return to Australia.
“She will travel to Australia for the medical treatment she needs,” Mr Dutton said.
“I will be guided by what is in her best interests, and I will be guided by the advice of the doctors as to what is in her best interests.”
Mr Dutton says Abyan’s “individual privacy is very important”, and would not speculate on whether she would go ahead with the termination.
He did say that Abyan will also receive mental health treatment while she is in Australia.

The decision comes just hours after the United Nations High Commissioner for Human Rights Rupert Colville, called on Australia to provide medical care fast.
"She needs an option to obtain adequate mental and physical care and to terminate her pregnancy if she desires," he said.
Rupert Colville says the UN is disturbed by the state of affairs on the small Pacific island.
“We are aware of a growing number of sexual assault and rape allegations since Australia restarted its policy of transferring asylum seekers to Nauru for processing in 2012," Mr Colville said.
There was also further pressure today from refugee advocates who rallied against the operator of the detention centres on Nauru and Manus Island.
The chant "free the refugees, free the refugees" echoed throughout Sydney’s CBD.
The epicentre of the passionate cries: The Mint on Macquarie Street, outside the Annual General Meeting (AGM) for Transfield Services.
Transfield operates the detention centres on Nauru and Manus Island.
Protesters are angry about its operations.

"We need to bring asylum seekers to Australia and do the processing here," said one of the protesters named Pip.
"Until the camps are closed we are going to follow Transfield. We have been hunting them down since early 2014," added fellow rallier Liz Thompson.
Mohamed Ali Baqiri, who was held at Nauru for three years from 2001 to 2004, says Abyan's case is not an isolated incident.
"We as kids we were witnessing so many horrible things like fellow detainees trying to commit suicide," he said.
“The conditions there were disgusting. Ten years later, people are still suffering.”
A report by activist group No Business in Abuse, which is associated with GetUp!, has detailed 47 abuse violations on Australian detention centres.
In response, Transfield says it cannot be held responsible for Government policy.
In a statement, the company claimed the report "continues to materially misrepresent statistics in order to support unjustifiable claims”
Transfield added it has “zero tolerance for abuse".
But Shen Narayansamy, who oversaw the report, believes Transfield is “clearly responsible”.
"What we are talking about is the mass violation of international law, and no company and no human being is allowed to do that just because the Government asked them to," she said.
Unions who represent staff who work at the detention centres say they are also worried.
They believe Transfield needs to ensure it upholds human rights principles for all detainees.
Meanwhile, federal government efforts to strike a deal with the Philippines to permanently relocate asylum seekers now held in Australian detention camps on Nauru and Manus Island have hit trouble.
The president of the Philippines, Benigno Aquino, has said his country has "no capacity" to assist Australia.
"If this proposed agreement is not one of a transitory nature, is not one of just being a transit point but actually relocating this people here, and we feel we are not in a capacity at this point in time to afford permanent residency to this people," President Aquino said.
Opposition leader Bill Shorten believes that should not be the end of the matter.
“To me, the Government needs to redouble its efforts with Thailand, with Malaysia, with Indonesia, with the Philippines,” he said.
Peter Dutton says he welcomes those comments, but remained coy on the next move.
