Oh, there have certainly been problems in Australia recently - especially in my state of Victoria where the state government has gone very dictatorial.
But there is a huge difference between what a state government has been doing and what the country as a whole is like.
Australia is not any sort of dictatorship - Victoria, specifically, arguably could be said to be flirting along those lines.
As for why there have been large protests in Australia - that's a lot more complicated than you probably know.
While allowing for a generous amount of exaggeration, what I read about what is going on in Australia is extremely concerning.
