Nine Chair Catherine West to Step Down as Peter Tonagh Named Successor in November

The move follows a governance reset after a culture crisis, with cash from the Domain sale shaping the next phase under new leadership.

Overview

  • Catherine West will resign as chair and leave the board at Nine’s annual general meeting on November 7, ending about 18 months in the role.
  • Peter Tonagh, who joined the board in January 2025 and previously served as ABC deputy chair, will assume the chair after the AGM.
  • West’s tenure included commissioning a workforce culture review that reported bullying and sexual harassment concerns and set reform in motion.
  • Nine sold its 60% stake in Domain for about $3 billion, receiving roughly $1.4 billion and paying a special dividend, leaving significant cash for strategic decisions.
  • Major shareholder Bruce Gordon holds 19.9% of Nine with derivatives lifting his economic interest to about 25%, and reporting suggests he may seek greater influence as investors weigh governance, including a 17% vote against West’s re-election in 2024.
