Eight security guards from Australia's detention centre in Nauru who attended a recent Reclaim Australia rally and posted a series of anti-Islamic rants on social media have been stood down and face investigation.
Australian media reports say the group - seven of whom are former Australian Defence personnel - are part of the emergency response team on Nauru and are employed by Wilson Security.
A spokesman for Transfield Services, which engages Wilson staff as subcontractors, said the Facebook posts by the men, which included a group picture with Pauline Hanson at the Reclaim rally in Brisbane earlier this month, were unacceptable and would be investigated.
A spokesman for the Immigration Department says service provider staff were expected to act appropriately and with integrity in all their dealings with the people in their care.
