James Chessell steps down as editor-in-chief of The Australian Financial Review to join a new media start-up, according to reports from multiple outlets. His departure triggers a leadership change at the paper.

Following Chessell’s exit, The Australian Financial Review’s editor Cosima Marriner is appointed as editor-in-chief. Sources say her appointment makes her the first woman to hold the editor-in-chief position at the publication. Coverage across the outlets focuses on the transition in senior leadership, highlighting both Chessell’s move and Marriner’s new role.

While all accounts agree on the key facts of the personnel change and Marriner’s appointment, they primarily differ in framing and regional emphasis rather than providing conflicting details about the transition itself. The reports consistently present the shift as a planned change in editorial leadership connected to Chessell’s next career step, with Marriner taking over the top role at the paper.
