So you think just because you live in Australia we are immune from what's happening to America? How do you feel about traffic cameras being set up to photograph your family in your car and recording your travel movements and putting all that information into a data base?
Who gave our government permission to do this? What do they intend to do with the information? I guess, what does it matter? Your mobile phone records all your personal movements. Your new GPS unit records your vehicular movements from satellites in space (GPS records in the UK are already being used to convict criminals). Your front yard has been put on Google Maps Street View, your backyard on Google Earth. Is this the Australia you remember from your childhood? It's all happened in the last 20 years.
A control grid of Orwellian proportions is being imposed upon us by stealth. You say "if you're not doing anything wrong, why would you be concerned?" If the apparatus is there to be used against the suspect, it can equally be misused against the innocent, if it suits the agenda of those in control.
So what should we do? I'll leave that for you to ponder. But bear in mind, one day, maybe sooner than you think, you may be forced to carry an implanted RFID chip that will be necessary to buy or sell anything. That sounds alot like the "mark of the beast" from Revelation, doesn't it? Thinking about where this could all be leading may help you know what you should do today whilst there is still an opportunity to do anything.
