My question is to the Minister for Transport and Regional Services. I refer to the minister’s answer yesterday and to his answer again today, for which I thank him, where he claimed that a new security fence was in place to secure the airport while construction was under way at Sydney airport. Is he aware that, until the matter was raised in this House yesterday, people accessing the construction site could get to the secure area of the airport through a hangar simply by removing a wooden chock—not unlike this one—from the hangar door? Minister, is a wooden chock like this the best practical measure the government can find to protect the Australian public from terror attacks at our busiest airport?
