A baby born this week will remain at the Villawood detention centre in Sydney, where his mother is being detained after being deemed a security threat.
The baby was born at a Sydney hospital on Tuesday night and was named Paarheepan, which means 'lighting of the world in Tamil', CNN reported.
The baby's mother, a Sri Lankan woman named Ranjini, is part of a group of 56 refugees who failed security assessments by the Australian Security Intelligence Organisation (ASIO).
Ranjini has two other children with her at the Villawood detention centre, and decided to keep the new-born with her even though he is allowed to leave. Ranjini was granted refugee status at the end of 2012, after being held on Christmas Island since April 2010.
She was told she needed just one more security check before her and her children could be granted permanent visas. But that check failed, reports said.

Ranjini's case, along with 56 others, is being reviewed by retired Federal Court judge Margaret Stone.
She was appointed in October 2012, six months after a Senate Committee report suggested that cases of indefinite detention should be subject to review.
Because she has already been found to be legitimate refugee, Ranjini can't be deported, but her 'high risk' status prevents her from being released.
"Thus far, the federal government has maintained that all of these people should remain in indefinitely incarcerated on the basis of assessments by ASIO that these people pose a risk," Ranjini's lawyer, Refugee and Immigration Legal Centre executive director David Manne told the ABC.
Her husband Ganesh, who met her when she was living in community detention, is allowed to visit under the regular immigration department regime.
ASIO said in a statement it only issued adverse security assessments where serious security risks were identified.
"They make up less than half of 1 per cent of all visa security assessments undertaken," it said in a statement.
"Security assessments are not character checks - they are an assessment of the risk an individual may pose to security, and may refer to terrorism, the promotion of communal violence and acts of espionage or sabotage."
"ASIO does not disclose national security classified information to visa applicants where such information would reveal ASIO's sources, methods and capabilities."
The Department of Immigration and Citizenship has a policy of not commenting on individual refugee cases.
