Dissident artist Ai Weiwei has brought his campaign in support of refugees to Australia.

The 60-year old has become a vocal campaigner on migration as the number of people forced from their homes, largely by violence and war, reaches into the millions.

Ai has unveiled a giant artwork depicting asylum seekers.  It’s a 60-metre-long inflatable raft, carrying about 300 oversized human figures.

He will also premier his new feature-length film, “Human Flow” as part of the the Sydney Bieanale at the city’s Opera House tomorrow.
