Around 300 Melburnians have lined up to become part of the world's largest toilet queue.
They are hoping to break a world record, along with people from around the world, to raise awareness about the lack of clean toilets and water in developing countries.
About 4,000 children die each day from preventable diseases in some parts of the world.
WaterAid Australia chief executive Adam Laidlaw says the worldwide Guinness World Record event kicked off at Federation Square this morning.
"Because of the time difference, Australia and Melbourne will be the first event," he said.
"And then we'll see events in 70 countries around the world from Sudan to Sweden, Benin to Brazil, in fact it's a kind of A to Z of events around the world to draw attention to this issue."
