The daughter of Mineral Resources chief executive Chris Ellison has earned millions of dollars in undisclosed fees after her company was given preferential treatment to help ship the group’s iron ore exports, according to governance advisory group Ownership Matters.

An analysis of port records shows that Ship Agency Services, founded by Kristy-Lee Craker in 2011, has made as much as $10 million through hundreds of ships that have loaded Mineral Resources iron ore since SAS was set up in 2011.
