Georgina Rinehart, 57
$9 billion
Mining, Australia
High iron ore prices and rising exports to China more than quadrupled her fortune in one year, but it was domestic issues that put her in the headlines. A new “super-tax” proposed by the Australian Government on iron ore and coal triggered a sharp reaction by the normally reclusive Rinehart who, in one cameo performance, mounted a flatbed truck with fellow iron ore billionaire, Andrew Forrest, to chant anti-tax slogans. That performance was followed by a surprise purchase of a 10% stake in a television network, perhaps to further her crusade against the mining tax. Rinehart is expanding her fortune via direct interests in mining, initially iron ore, but with coal likely to come if a trial mine performs as expected.
