Once again this needs context that I'm assuming most international viewers/commentators lack,or can't be bothered with, or are deliberately omitting.
Firstly, the livestreams are good for seeing what's going on on the ground and for tracking where things are operating during the day (like when a small group of protesters invaded a shopping centre carpark/playground/picnic area a day or two after that protest... in an area that borderline openly hostile to them). This is important for people like me living this at the moment who are literally just trying to head out with their toddlers and don't want to be caught up with the radical/violent protesters. Just looking up in the sky is often a good hint for us as the police helicopters generally follow that days main groups. But one has to be careful viewing the footage afterwards, as it's often deliberately edited and taken out of context for propaganda purposes.
therealrukshan (the linked streamer) for instance is far from independent or objective media. he's far-right/trump aligned (yes, it's Australia, no it doesn't make sense) and has been known to give running commentary bordering on "reality denial" imo. in the background we also have telegram and messaging groups going on at the same time, so watching one view after the fact still often departs from the context of what was happening or being said at the time.
It happens that I was watching the particular stream linked in the video (and others) in real time, so I'm pretty familiar with the events and context of that protest.
For those wondering, this was day 3 of a series of events. If I've got my timelines right, the violent protests in the previous article happened the weekend before and have another additional layer of context on top (they happened after police shut-down the public transport into the city, and my neighbourhood, for the morning to try to hinder an organised protest that would be taking part during our latest delta-ourbreak: keeping in mind we don't yet have widespread vaccine coverage due to supply failures/AZ hesitancy AND practically no recieved immunity due to elimination of the earlier coronavirus transmissions here locally).
Following that, a series of unfortunate events took place. Restrictions (and compulsory vaccines) were announced on the construction industry, which compared to other industries during our lockdowns had been allowed to operate with relative freedom.
Subsequently a borderline riot took place outside a union office in the city that afternoon: comprised of legitimate construction staff, but with the context of the far right groups also messaging people to buy/wear uniforms and get down there to generally cause trouble. long story short: shut-downs of construction for two weeks announced.
the next day what I'll call the tradespeople march happened primarily in the city, which was easily the largest protest so far. predominantly men affected by the previous decisions + a smattering of the far right still "strategising". they basically took over the (comparatively abandoned) cbd and then marched down and blocked a freeway. they promised to continue protesting every day against the shut-downs/ lockdowns/vaccine mandates. This was not a union (who is pro- vaccine anti mandate) mandated protest, which is a whole other layer of context itself. police were present in large numbers after the previous days/weekends violence, but large scale destruction/clashes were more or less avoided.
the next day a smaller protest started in the city again, and after ambling around for a while ended up spontaneously marching to and occupying a war memorial just south of the city. This in itself was a somewhat "controversial" action (and personally, partly responsible for the fizzling of any popular remaining support, as amongst the community it was seen as borderline sacrilege/profanity). this is the edited footage above. it resulted in a multi-hour stand off with riot police while they occupied the space. the police offered safe passage away from the shrine for several hours for protesters, and numbers dwindled into the late afternoon until there were a couple of hundred more radical holdouts remaining at the end of the day refusing to leave. this was when the police cleared the space with the riot-squad.
from this point, popular support seems to have dwindled. the tradespeople have largely stopped taking part in the numbers of the earlier days, and the following protests have numbered in the small hundred (if that) compared to the relative success/numbers of the first tradespeople protest, and seems to largely now be composed of the remaining telegram/facebook brigade of far-right and... with all due respect...relative deluded crazies.
