As an aside, are the protests in Melbourne still mainly by construction workers? I believe your press calls them tradies.
Strictly speaking, there's a bit of a difference between tradies and construction workers - a lot of construction workers are tradies, but not all tradies are construction workers :).
Honestly, I'm not sure who the protesters are right now. Yes, it started out with construction workers but a lot of others got involved and now it seems to be made up of all sorts of people with disagreements with the government some of which aren't compatible. My feeling is that construction workers only represent a small proportion at this point, but I haven't checked.
And construction workers are allowed to go back to work on Tuesday, the two week suspension of work being over (unless the Premier changes his mind) - the ones who object to mandatory vaccinations will still have a beef at that point, but a lot of the protesting was about the fact they weren't allowed to work and that's not going to be the case anymore.
