A man with serious criminal convictions is to be deported to New Zealand because he is too much of a risk to the safety of Australian citizens.
Marouna Williams, 24, is a New Zealand citizen who spent most of his childhood in the Cook Islands and has lived in Australia since 1998.
He has told the Administrative Appeals Tribunal of Australia that he has no recollection of living in New Zealand.
Marouna Williams has convictions for unprovoked attacks on train passengers which left one man in a coma for months.
Some of his offences were committed with his older brother and two cousins.
The tribunal has upheld a decision of the Minister for Immigration and Citizenship to deport Marouna Williams to New Zealand where his parents are living.
His father, Abela Williams, who lives in Hastings, says his son considers Australia home.
"We're devastated because we didn't think he would be deported and we were hoping that he'd remain in Australia because he paid for his penalty."
Abela Williams says his son's partner and nearly all of his siblings live in Australia.
Mr Williams says his son was very young when he committed his crimes and he doesn't believe he'll reoffend.
