Who Is the Richest Woman in Australia
Gina Rinehart is the richest woman in Australia, with a net worth estimated at 37.1 billion dollars by Forbes in its latest billionaires ranking. She inherited a controlling stake in Hancock Prospecting and expanded the family mining business into a diversified resources group spanning iron ore, coal, and petroleum projects across Australia and overseas.
Rinehart remains the top-ranked Australian woman on the global billionaires list, ahead of other female founders and heirs in technology, retail, and healthcare. Her wealth is tied directly to the performance of Hancock Prospecting and its joint ventures with major miners, including Rio Tinto and BHP.
How She Built Her Fortune
Hancock Prospecting grew from a small cattle and mining enterprise into one of Australia's largest private resource companies after Rinehart took control following her father's death. The company holds substantial royalties and equity positions in major iron ore mines in the Pilbara region, which supply steelmakers in Asia and Europe.
Beyond mining, Rinehart has invested in agriculture, hospitality, and energy through Hancock Prospecting subsidiaries and strategic partnerships. Her portfolio includes stakes in Australian agricultural land, cattle stations, and renewable energy projects, with additional exposure to global resources via publicly traded holdings and private equity vehicles.
