This move by the Federal Government is absolute nonsense.
The only reason why an armed terrorist might board an aircraft here in Australia is if he was pissed off with our government for interfering in overseas countries, or perhaps for allowing our country to be controlled by overseas organizations. It is only minutely possible that metal detector and handgoods x-ray processes would not detect such a minimal threat.
It is far more likely that, like in the US, a rebel is set up with some minor or fake explosive device with the intention of proving the body scans necessary.
The solution would be for our foreign policies to be based on humane principles.
Meanwhile, thousands of innocent passengers are subjected to unnecessary scrutiny, inconvenience, probable health risks and delays, while the Federal Police and security organizations play games to earn their pay.
