A six-year-old South Africa-born boy may face being deported from Australia if local authorities don't renew his passport. The child's father, a Durban electrician, and his former partner, the boy's mother, have taken the Minister of Home Affairs and its director-general to the Durban High Court to remove a block on the issuing of a passport for the boy and to process a renewal application for him.In the father's affidavit, lodged in July, he said after he and his partner split up, he found she was taking his son to Australia. He approached the Children's Court in Durban in March 2010 to stop her leaving with the child by asking the Department of Home Affairs to block the child's exit.He was granted the order, but it was not implemented immediately."There was a delay in the Children's Court informing Home Affairs to put a hold. Home Affairs were informed only in August 2010, when my son had already left with his mother," said the father.He said he was initially very angry with his former partner for leaving with their son, but they came to an understanding that it was in the child's best interest for him to remain in Australia with his mother."I instructed the offices of the Family Advocate to withdraw the application in May 2011. It informed Australian authorities."He did not deal with the stop on the Home Affairs system and the child's passport expired in February last year.He said his child's mother had been liaising with a Home Affairs employee in Pretoria, who advised that only a court order would suffice to have the block lifted."This stop was requested at my request. My child's mom and I are now in agreement that it is in the child's best interest that the stop be removed," he said.He said because his son's passport had expired, he could not obtain a new visa and faces the possibility of losing his place in school, his medical care and being deported from Australia.The boy is able to stay as the family have obtained a bridging visa, but they are uncertain if this can be repeatedly extended."It is important that my son remain in Australia. Not only has he settled in a stable family environment, surrounded by grandparents, aunts, uncles, cousins and siblings, he has been enjoying his time at school."..
