Australia is being encouraged to take a lead in ending modern slavery by formally establishing a "Modern Slavery Act."
A federal inquiry is underway and has moved to Melbourne, where it has heard testimony from a slavery victim and a Hollywood superstar.
Modern slavery describes a range of exploitative practices including human trafficking, forced labour, wage exploitation, forced marriage and debt bondage.
It's found in a range of economic activity such as domestic work, construction, agriculture, manufacturing, sexual exploitation and forced begging.
The 2016 Global Slavery Index estimated there are almost 46-million slavery victims around the world.
Two-thirds of those live in the Asia Pacific region, with about 4,000 thought to be in Australia
