As noted previously, the government and police have a habit of regarding protest as inherently disorderly and disruptive, if not as a "breach of the peace". And the application to the common protest tactic of blockading a building is obvious.
Fascinatingly, the bill's BORA vet finds that the anti-begging and anti-rough sleeping provisions are disproportionate limitations on the freedoms of expression and movement, but does not consider the obvious application to protests at all. Which both shows a distinct lack of imagination and is a complete dereliction of duty on the Attorney-General's part.
This law can be used to limit fundamental rights to protest. Given police attitudes, it will inevitably be used to do so. If that is not the intent, then it needs a Terrorism Suppression Act-style clause excluding its application to any protest, strike, or lockout. If the regime fails to add one, then we should regard the suppression of protest as their intent, and the destruction of our democracy as their ultimate goal. It is that simple.
