An Irish family at risk of being deported because of their son’s cystic fibrosis has been given renewed hope with news their application for permanent residency will be reviewed.

The child was deemed a “burden” to taxpayers, as treatment for his condition exceeds $40,000 per year, which is not allowed under Australian migration law.

The mother of the child, Christine Hyde, says the family's biggest concern was their child’s medication was not readily available in Ireland and hoped their application for permanent residency would be approved.
