There have been clashes between police and a large group of protesters outside the Melbourne Convention and Exhibition Centre where a major defence and weapons expo is being held.
Hundreds of officers have been called in for what Victoria Police say is their biggest operation since the S11 protests outside the World Economic Forum in Melbourne 24 years ago.
What's next?
Police and protesters are expected to remain on scene in large numbers throughout the conference.
[Premier Jacinta Allan] also defended the state government's sponsorship of the Land Forces conference, and said delegates attending the event had the right to gather.
"Any industry deserves the right to have these sort of events in a peaceful and respectful way."
When your industry is undeniably dedicated to murder and maim, you don't deserve peace (or, for that matter, respect).
