Baby Ferouz spends first birthday in detention

THE Australian-born baby who is the subject of a high-profile legal challenge surrounding his citizenship has spent his first birthday behind razor wire in a Darwin detention centre.

Baby Ferouz's plight made headlines across the nation after the Federal Government denied him a protection visa saying he was an unauthorised maritime arrival.

Lawyers for the baby challenged the ruling, but the Brisbane Federal Circuit Court rejected the application last month.

Ferouz was born prematurely in Brisbane's Mater Hospital in November, 2013, after his mother was transferred from the detention centre on Nauru due to concerns about her pregnancy.

Maurice Blackburn senior associate Murray Watt said on Thursday Ferouz's first birthday was another sad reminder of the huge human and financial cost of keeping children and families in detention.

"The first birthday of any child should be cause for celebration, but for Ferouz and his family it will be just another day behind razor wire," he said.

"Most Australian kids would be spending their first birthday with cake, presents and learning to walk and play outside.

"Instead, Ferouz, who was born in Brisbane, remains locked up in detention, with an uncertain future."

The Federal Court's decision last month is the subject of an appeal.
