Tim Ewington

CEO, Digital Futures Australia · Executive Coach

Tim brings more than two decades leading businesses in recruitment and workforce solutions, advising global corporates and public sector organisations on how they hire, develop and retain people. That background gives him a clear-eyed understanding of how hiring decisions actually get made, and where experienced professionals tend to get overlooked — not because of capability, but because of how they are presenting themselves in a changed market.

Before that, he played and captained rugby at a high level through the sport’s transition from amateur to professional — navigating real institutional resistance while everything around the game was changing. It shaped how he thinks about identity, transition, and what it takes to bring people through change. He draws on that same thinking in his coaching, helping professionals reframe their story and move forward with clarity.

Marcus works as a career transition coach helping executives and functional leaders on optimising their personal value proposition and how to best position themselves in the job market for their next role or career change.
