The wealthiest woman in Australia has recently become the wealthiest woman in the world.
Mining magnate Gina Rinehart's fortune has reached a net worth of $29b, thanks in part to her iron-ore company becoming a stand-out player in Australia's booming mining sector.
As the price of iron-ore has shot up, so has Rinehart's wealth.
