Someone’s freedom to protest is not more important than someone else’s freedom to use that same space to get to work, live their life, etc. Protests have always needed to be booked in advance and are essentially always approved (with police protection included for neo nazis etc).
You seem to be describing the freedom of America (a right to a gun, but not a right to be free from the fear of getting shot) but it’s not like that everywhere, see even more extreme examples like the “guilty until proven innocent” case of libel in Australia.
I’m not saying either way is better or worse, just that this is the status quo really for Australia.
