Hundreds of climate protesters gathered at the Melbourne Convention Centre to stop the international mining conference.
Starting at 6 am on Tuesday, activists from 11 different groups began to block access to the Melbourne Convention and Exhibition Centre in police-intensive conditions.
A video broadcast by the Nine Network showed a clash between the police and the protesters, protesters shouting and raising slogans calling for mining to be “shut down” as they tried to push back to the police line.
The International Mining and Resources Conference is Australia's largest annual industrial event, attracting delegates from the resources, investment and technology sectors.
More than 7,000 delegates from about 100 countries participated in the three-day conference, and organisers said the protests were based on misunderstandings about the mining industry.
