World leaders convened in Brisbane, Australia for the 2014 G20 economic summit on Friday and were greeted not only by posh lunches but also by hundreds of protesters. The summit, which usually ends without many binding decisions being made, has become an annual gathering for protests of all shapes and sizes and on all sorts of issues.

From the entertaining, to the elaborate, to the downright serious, here’s some photos of the crowds that greeted the world’s most powerful leaders, including U.S. President Barack Obama, Russian President Vladimir Putin and Chinese President Xi Jinping.

The best costumes went to this group who made masks caricaturing world leaders. They were dressed as Australian lifeguards and were asking for equality on the world stage:
