Josh Robenstone is probably Melbourne's best photographer. Not only does he have an impeccable sense of composition, but he knows a good cause when he sees it and doesn't hesitate to get involved. Over the years he has shot everything from the cities of Melbourne, Beijing, and New York to series on Melbourne's street artists and the G20 riots, all while finding the time to mentor aspiring young photographers.

The images in this feed are taken from his documentary series on Qatar's migrant workers, who are today's equivalent of slaves, often becoming trapped in labour camps with unsanitary living conditions and little to no pay.
