REFUGEE advocates “fabricated’’ claims that a 23-year old Somali woman allegedly raped on Nauru still wanted an abortion in Australia, Immigration Minister Peter Dutton has said.

The cost of her charter flight to Australia for the abortion, which the Prime Minister insists she “changed her mind’’ over could be over $100,000.

The Sunday Telegraph understands she was the only asylum seeker passenger on the international charter flight to and from Nauru for the purpose of travelling to Australia for an abortion, but was accompanied by security and medical escorts.

Two asylum seekers have alleged they were raped on Nauru. The woman flown to Australia for the termination has never made a formal complaint to police according to Naurun officials.

The 23-year old is believed to be around 14 weeks pregnant.

In an earlier privacy breach, a second alleged rape victim, 26, had her name and intimate details of her case was published by an Australian based PR company working for Nauru.

The 26 year-old Somali woman’s alleged rape was reported and investigated. However, Nauru police have closed the case arguing there is insufficient evidence. Her lawyers have argued the perpetrator is a member of the Nauruan police reserves, suggesting it may have contributed to a lack of enthusiasm for investigating the matter.

Refugee Action Collective yesterday claimed the 23-year old woman had told advocates that she had not “changed her mind’’ about the termination as Prime Minister Malcolm Turnbull asserted but had simply sought counselling.

However, in an strongly worded attack, Mr Dutton said last night some advocates should “ashamed of their lies’’ over her pregnancy termination.

“A woman was flown by charter flight from Nauru to Sydney for a pregnancy termination,’’ Mr Dutton said.

“The woman has decided not to proceed with the termination. Comments from some advocates to the contrary are a fabrication, while others appear to be using this woman’s circumstance for their own political agenda.

“They should be ashamed of their lies. The woman was chartered back to Nauru. The woman was bought to Australia for medical attention not for a migration outcome.’’

Lawyers for the Somali woman raped on Nauru who had asked for an abortion in Australia have flatly rejected Prime Minister Turnbull’s claim the woman decided against an abortion after she was flown to Australia for the procedure.

“The information I have is that woman in question changed her mind about seeking a termination and was deemed fit to fly,” Mr Turnbull told reporters in New Zealand on Saturday.

Special counsel for Shine Lawyers George Newhouse, said his client still wanted an abortion.

“Our client has not decided to refuse a termination and you have completely misunderstood or misconstrued her position.’’ he said.

“Our client has the right to counselling before a termination and to understand the procedure.’’

Mr Dutton warned that Australia would now allow medical treatment to be used by lawyers as a ruse to deliver legal outcomes.

Last week he accused some refugees of running “a racket’’ to use medical treatment as an excuse to come to Australia and then seek legal injunctions to prevent their returns.

Greens Senator Sarah Hanson-Young has called for an independent investigation into the matter.

“It is hard to fathom a more brutal way of treating a scared young woman who has been raped and is struggling with the decision to terminate the pregnancy,” Senator Hanson-Young said in a statement.

“Malcolm Turnbull must call his immigration minister into line. This beating up of vulnerable refugee women and abuse of their rights to lawyers, doctors and freedom has gone way too far.”
