The Australian Financial Review’s investigation into the tax dealings of Mineral Resources founder Chris Ellison, in-depth look at Fortescue’s Andrew Forrest, and visual deep dive into the opaque world of philanthropy have scored gongs at Australian journalism’s top honours, the Walkley Awards.

At a ceremony at the ICC Sydney on Thursday night, Mark Di Stefano and Neil Chenoweth were given the award for best business journalism for their investigation into Ellison, which sparked a share price rout and (now broken) promise from the billionaire to step down as chief executive.
