I'm not sure what Australia you live in.
We are currently torturing asylum seekers, with unlimited detention periods (the only nation on earth who allows this). A recent whistleblower that showed corruption within the ATO (to Americans: the IRS) is facing charges that would land him with 160 years in prison. We've neglected and abused the native population to the point that Aboriginal teenager suicide rates are among the highest in the world. Our education system is failing to the point where our education system has the same standards as third world nations -- we rank lower in science and maths than Kazakhstan. In 2015, laws were passed to punish whistleblowers, journalists, AND THE PUBLIC if ASIO (Americans: the NSA) information becomes public. We are the only nation on earth to pass draconian anti-privacy laws that other nations' leaders can only dream of. We don't have any laws guaranteeing freedom of speech, privacy, or any other freedoms we take for granted -- and we are the only western democracy where this is the case.
Don't get me wrong, I hope Australia does get better -- after all, I deeply want it to because I've grown up here. But if you think that the Australia of today is in any way "one of the most open, free and fair places in the world" you're simply mistaken. Yes it's better than living in Saudi Arabia but that shouldn't be an accomplishment.
