I'm glad I don't live in Australia. I have numerous items like the ones mentioned above. That certainly does not make me a terrorist.
This is just part of the evidence, they are not being prosecuted for having this in their possession, but for planning terror attacks.
Australia foils 'terror attack'

Australian police say they have foiled a terrorist attack in the final stages of its preparation, after 16 people were arrested in Sydney and Melbourne.
New South Wales police chief Ken Moroney said a "potentially catastrophic attack" had been averted.
One suspect was shot and wounded during a raid in Sydney. Chemicals, weapons, and computers were seized, police said.
The raids involved about 500 police officers and followed a 16-month investigation, officials said.
"I'm satisfied that we have disrupted what I would regard as the final stages of a large-scale terrorist attack, or the launch of a terrorist attack," Mr Moroney told Australia's ABC radio.
