As long as theres a communication blackout, the Australian state can do whatever it wants to the Truckers without consequences. Anyone in Australia who can make it, ought to carpool, and drop off volunteers to film the protests, so the police can't get away with anything. There will need to be people also willing to pick up these videos, and upload them from somewhere else because the next thing the state is going to do is use radio and cell jammers, or geofence the area.
