The Migration Amendment Bill 2015 is currently before parliament. This bill gives security officers in Australia's off-shore detention centres unchecked power to use force against asylum seekers in any circumstance they think reasonable. The bill introduces a subjective test whereby security officers themselves get to decide if violence is warranted. Where excessive force is used in most cases the officers will be immune from legal action.
Meanwhile Transfield Services, who runs the off-shore detention centres, has warned staff they can be fired as a result of who their friends are on Facebook, who follows them on Twitter or for being a member of a church or political party opposed to asylum seeker policy.
So while Transfield and the government trusts security officers to decide for themselves whether or not they can beat up asylum seekers, they don't trust them to talk with anyone who thinks that might not be a good thing.
