A few years ago, the federal government dissolved the Australian Customs and Border Protection Service, which checked peoples passports and asked them stern questions about the suspicious grass dolls they bought in Vietnam. If you did something really stupid, a customs officer might point a pistol at you.
They replaced it with the Australian Border Force, who despite formally not being a military force (how-dare-you-suggest-it-you-unaustralian-piece-of-shit-do-we-need-to-check-your-passport) are armed with the same Steyr AUG assault rifles that are used by the Australian Army and very much like to show them off at all public appearances.
Within literally less than a month of it's formation the government attempted to deploy this new department, which is under unusually direct control of parliament for an armed force in Australia, to spot check for expired visas on the streets of Melbourne. Fortunately, we never got to find out how the Aussie Stazi were going to tell the difference between visitors and normal Australians. Australians are not required to carry ID and due to our wonderful melting pot of cultures cannot always be distinguished by accent. As it happened, Melbourne did us proud and brought the city to a halt in protest:

Meanwhile, in my home state, a new government has just been elected on the back of an unironic campaign promise to deploy sniffer dogs in schools to ensure children don't have drugs:

One of the reasons I left Australia is that I am expecting them to close the borders and start granting exit visas within the next 5-10 years. They've already successfully used "won't someone think of the children" to establish precedent for denying people freedom to exit the country: https://www.nytimes.com/2017/12/13/world/australia/pedophile...
The next step will be expanding it to preventing people with "dangerous ideas" from "embarrassing Australia and endangering our neighbors". I expect to see vocal anti-vaxxer proponents denied permission to travel within about 3 years. It'll creep from there.
Basically what's happening is that Australia is sick to death of its two identical political parties, and they're both losing support rapidly in both state and federal governments. Understandably, neither one is willing to accept that it might just not be wanted by the new generation, so both are grasping for provable victories they can display like trophies at elections. This has resulted in huge tax increases on booze and cigarettes, burdensome increases in the difficulty of teenagers getting drivers licenses and reductions in the utility of those licenses, sweeping surveillance and data retention laws, attempts to criminalize the teaching of encryption algorithms, big increases in security theater at airports and a litany of other annoyances.
Mostly I want the government to just fuck off and leave me alone, but it won't play ball. So I fucked off instead.
