Military WITH GUNS walking down a suburbian street in Currajong NSW.

I tried to find some context online, but haven't been able to. There could be a very reasonable explanation for it but I can't find it.

Does anyone know the meaning of this?

Was it a drill? Email us if you know please admin@reignitedemocracyaustralia.com.au
