Australia's richest person Gina Rinehart is moving to one day hand over the family's $10 billion dynasty to her youngest child.
Ginia Rinehart, 25, is being favoured as her three siblings challenge their mother in the NSW Supreme Court in an attempt to remove her as head of a family trust that controls a quarter of the family's fortune, The Australian reports.
In a major shake-up, Mrs Rinehart appointed Ginia as a director of the family's Hancock Prospecting on December 5, replacing the long-serving Terry Walsh.
Ginia has also been appointed as director of Hope Downs Marketing Company, the joint venture with mining giant Rio Tinto that runs the Hope Downs project in the Pilbara.
She has also replaced her older sister Bianca on the board of one of the family's key companies HMHT Investments.
The latest moves put Ginia at the top of the family dynasty, which includes mining projects in Western Australia and Queensland as well as key stakes in the Ten Network and Fairfax Media.
Gina Rinehart is the heiress of Hancock Prospecting and the daughter of the late mining magnate Lang Hancock, who rose to fame for discovering the world's largest iron ore deposit in 1952.
