Mr. Pratt was the face of Australia’s richest family, presiding over a global recycled-cardboard and packaging empire. Like many in the blue-chip business world, he would become a late Trump devotee. Pratt tops the 2017 Financial Review Rich List for the first time since 2009, driven by the stellar growth of his Pratt Industries cardboard box manufacturing and recyling business in the United States. Pratt, who is executive chairman of Pratt Industries and the cardboard box and recycling giant Visy in Australia, took over the US business in 1991. He has overseen the rapid growth of Pratt Industries in America, where it now employs 7000 people. Pratt inherited the helm of Visy Industries from his late father Richard in 2009 and now spends more time in Australia, where his sisters Heloise Pratt and Fiona Geminder also have an ownership stake in Visy.
