I agree that Australia is being used as the canary in the coalmine for these authoritarian-leaning laws because the Australian people are, in general, entirely apathetic to politics that doesn't immediately affect them (Australians historically vote for the simple, and therefore unlikely in reality, immediate advantage - often in the form of tax cuts or inverse threats of tax hikes - at the expense of the future) - which therefore normalises these laws for the rest of the 5-eyes / western world.
I have my thought-fingers around an idea to offer some kind of privacy-as-a-service service, but it'd have to be incorporated outside of Australia and its ownership made opaque through the use of shell companies - thankfully (/s) Australia has no legislation against conducting business in the country with such untraceable ownership (I think it was the Panama Papers that revealed both Wilson[0][1] Security and SA Power Networks[2][3] had opaque international ownership structures and it was essentially unknown which individuals were actually responsible for their operations - Wilson Security has government contracts and SA Power Networks literally run the power grid in South Australia).
Australia doesn't have a terrorism problem, and yet is leading the charge in writing legislation to combat it. It smells long-rotten, but most of the Australian population have their noses buried in their socials.
Australia has a corporate tax collection problem that neither side of government want to touch with a ten-foot pole.
The small fish are easy to catch and therefore easy to score political points from. Legislation follows from this realization.
