He stresses that culture change requires alignment, leadership, and patience—it’s not a linear process, but one that can drive sustainable improvement.

Angela Ewers, Chief People Officer | ARN Media
Angela Ewers shares a deeply personal and practical reflection on her journey driving leadership and culture change at ARN. The decision to focus on these areas stemmed from a clear need to shift the organisation to meet both internal challenges and evolving external demands. The business strategy required transformation—and with that came the realisation that developing the right leaders, demonstrating the right behaviours, was the key to unlocking meaningful progress.
Angela emphasises the importance of helping leaders grow their capability and confidence—to “let go,” coach instead of control, and inspire teams to do their best work. By helping people shift their thinking styles and understand how those styles influence behaviour and results, the organisation saw clear improvements in engagement, innovation, teamwork, and pride.
Rachel Glasbergen, Senior Business Leader | Sanitarium Health and Wellbeing
Rachel Glasberger shares a powerful and inspiring story of how a constructive culture has been the cornerstone of success at Sanitarium—especially in the launch and growth of its new business unit, The Alternative Dairy Co. In just four years, this innovative brand, developed in response to a growing consumer trend for plant-based milks in specialty coffee, has grown to over $80 million in value. According to Rachel, culture was not just a contributor—it was a key enabler of that success.
Rachel’s leadership approach blends ambition with humility, structure with empowerment. She believes in setting a clear direction but also creating the environment for others to shine. As a result, the business hasn’t just achieved financial success—it’s unlocked people’s passion, built new capabilities, and strengthened partnerships both internally and externally.
