"Farrell’s barrister pushed the point that “national security” was not relevant for operations that were unlawful and the government’s incursions into Indonesian waters, which were covered in some of these logs, were unlawful in his view."Guardian Australia’s barrister Tom Brennan told the hearing:
“Security in the Asio act goes beyond that which is dealt within the FoI act, because it’s not limited to the security of the body politic. It’s directed also to the security of people.“There can be no doubt that people-smuggling activities are a matter of significant public interest … they are not in my submissions ones that rise as high as touching the security of the commonwealth.”According to the report Major General Bottrell, Commander of Operation Sovereign Borders testified
“Our greatest asset now is the scepticism of the potentially illegal immigrants..” “Much of our effort is aimed at educating people sitting there, that people smugglers are convincing to get on boats.”People smugglers would use the information about turnbacks to inform asylum seekers about how close they had got in their previous attempts to reach Australia. “Our efforts are to educate them about the dangers of that journey.” Bottrell argued that hiding this information from the public and from people smugglers was essential as part of that education effort."Security of the Commonwealth"
The exemption relied upon according to these reports (there may be others) is Section 33(a)(i) of the FOI Act: “A document is an exempt document if disclosure of the document under this Act:(a) would, or could reasonably be expected to, cause damage to: (i) the security of the Commonwealth...
The exemption is absolute- there is no weighing of public interest or other considerations that might favour disclosure.
The meaning of terms used in the exemption received the usual thorough analysis recently from AAT Deputy President Forgie in Prinn and Department of Defence. [58-96] citing many precedents from court decisions but none that appear directly to address the argument reportedly advanced by Tom Brennan.
Guidelines issued by Australian Information Commissioner
Also of interest in the Prinn case [47-57] Deputy President Forgie parted company with Senior Member Popple (as she had last December in Wood) who most recently in Jones said
"The FOI Guidelines are not binding, but decision makers, including this Tribunal, should apply the FOI Guidelines unless there are cogent reasons to the contrary."Deputy President Forgie:
53. I agree that they are not binding but I disagree that decision-makers, including this Tribunal, “should” apply the Guidelines. The obligation is to have “regard” to them i.e. “... to take into account; consider. ...”. It is not to “apply” them i.e. “... bring to bear, put into practical operation, as a principle, rule, law, etc ...”. Regard can only be had to them if they are made lawfully i.e. within the scope of the power conferred by s 93A and consistently with the FOI Act. Decision-makers cannot be required to have regard to the Guidelines in so far as they relate to the interpretation of the FOI Act. Section 93A(2) limits the power to issue Guidelines for the purposes of the performance of a function or the exercise of a power under that legislation. For those purposes, regard must be had to them and there can be no doubt about that. A modern statement of the importance of guidelines of this sort has been made in Plaintiff M64, to which I have referred at  above.
