Hey @ricardoa, sorry I missed this when you commented.

Yes, I remember having the same realisation around 2012... I talked to protestors at Occupy Melbourne and they said how the police had "kettled" them, stolen their musical instruments and broken them, thrown the instruments in garbage bags with horse poop on top. Soon afterward the Victorian government introduced a "move on" law which to me sounded very much like an anti protest law. Around that time I started to consider quitting the country quite seriously

I recommend Pimsleur or Michel Thomas audio courses to start learning Spanish. That definitely makes things easier. You don't need a visa to enter Mexico, but generally it makes it easier if you get one in Australia
