The Aussie crowd are very predictable as in wanting a fair go.
Even here on HC, we say, discuss the the company not the poster.
That was a setup with actors and cameraman, the crowd responded as predicted.
Who knows what their motive was.
I believe Muslims / islam are the instigator of hate.
Preaching death / hate to non believers and etc.in their book , on the streets and in Mosques.
Aussies are lovers , and are lay back fun seeking individuals at most.
They will defend anyone trying to take that lifestyle away from them and their children.
You are correct:
"The average Muslim is completely normal, the average Australian is completely normal."
but average normal people do not change the country or the World, they are just Pawns in the Game.
Read this somewhere:
"We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works."
Gun Owners are average normal people too.
Port Arthur comes to mind and the reaction with new Gun Laws.
Best way to go unnoticed is to assimilate and stop demanding special treatment.
