Aussie are no different to the average Brit, American or any other first world country..
We allow governments and corporate to continue to accumulate data about us without regard for the consequences. We freely post the minutia of our lives on so called social media, once assembled it so easy, the things one would dumpster dive is now laid out conveniently at our finger tips to search and correlate.
And we howl when this gets abused, yet we do little to change the situation, we line up for our free email account, knowing full well its being mined. We accept governments excuses we need to store and link everything together in one place. We put identifiers on census data so we make sure everyone completes it, for want reason likely nothing more than some mindless compliance.
For years others have been warning of the consequences of these honey pots, and to those would would blame the programmers, network and systems engineers have a look at yourself.. Is everything you have done is perfect. I certainly cant make that claim.
There does need to be consequences for corporate's and government but these consequences need to be painful and serious. Not some dinky fine that is a cost of doing business. Start jailing directors and you will quickly find the C-Suite quickly finding the $$ to properly support the necessary workers and upgrades.
But we also need to accept some responsibility as individuals.. The excuse is its inconvenient, too hard, or too slow I have heard a myriad of excuse to lower barriers. Privacy matters, but over time we have allowed or been lulled into thinking you don't have the right to privacy (or in Aussies case we don't have "rights"). Maybe I should misquote Benjamin Franklin
"Those who would give up Privacy, to purchase a little convenience, deserve neither Privacy nor Safety."
