The Australian Greens say Immigration Minister Scott Morrison should be sacked after his admission that some of the information he released after deadly rioting on Manus Island may have been incorrect.
Immigration Minister Scott Morrison says the "majority of the riotous behaviour" that killed an Iranian man and injured 62 other asylum seekers on Manus Island this week happened inside the Australian-run immigration detention centre, contradicting his earlier claims.
An independent investigation into the death of 23-year-old Reza Berati in Papua New Guinea is expected to take several months, but initial reports that the violence took place outside the centre's perimeter already look wide of the mark.
Greens leader Christine Milne on Sunday accused Mr Morrison of repeatedly misleading the Australian public over Manus Island, and called on Prime Minister Tony Abbott to sack him from the ministry.
"Prime Minister Abbott must take personal responsibility for thedeath of Reza Berati on Manus Island," Senator Milne told reportersin Hobart.
"He must close down Manus Island immediately and sack his minister Scott Morrison."
Mr Abbott and Mr Morrison had a duty of care for asylum seekers at the Manus Island facility, she said.
"A young man has been murdered in their care," she said.
Defending his initial version of what happened at the facility, Mr Morrison said it was important to providing a briefing in the immediate aftermath because of the "tragic death" of Iranian Reza Berati, 23.
"Information is rarely perfect so soon after the event," he said on Sunday.
"Any early reports are always qualified along these lines, as my report on that morning was."
The mistake was "regrettable", he said, but the information had been provided in "good faith".
In a statement, contractor G4S said that 'following new information to hand, G4S's earlier statements about events at Manus Island are currently under review.
Labor frontbencher and former immigration minister Chris Bowen said Mr Morrison had a "lot of explaining to do".
"These are difficult circumstances, and as a former immigration minister I think the primary responsibility on Scott Morrison is to be up front with the Australian people, to be transparent."
Opposition immigration spokesman Richard Marles said Morrison was unaware of what was happening at Manus Island.
"This is a man who has no idea of what the facts are", he said.
MORRISON BACKTRACKS ON STATEMENTS
Mr Morrison said on Saturday night that "further information I have now received casts further doubt on the initial advice that his injuries were sustained outside the centre."
"The precise nature of these events are the subject of the review and police investigation that has been initiated. It will be the task of that review and the police investigation to determine the facts of this incident."
Mr Morrison reiterated his position that it was in the best interest of those held in the centres to "conduct themselves appropriately", but said security workers must also behave properly.
"Service providers must conduct themselves lawfully and consistent with the service standards set out in their contract," he said.
"The independent review established by my department will look at the conduct of the service providers present on that evening, along with any other persons found to be present within the compound that night."
Security firm G4S handed control of the detention centre to Transfield Services on Saturday, with both firms promising to co-operate with the inquiry.
The review will be led by Robert Cornall, who undertook a previous inquiry under the Labor government into sexual abuse allegations on the PNG island.
The Prime Minister said on Sunday he had confidence in Mr Morrison, who was performing well in a job which was not for 'wimps.'
