2026 Women to Watch in Cybersecurity
2026 Women to Watch in Cybersecurity
In our recent “2026 Digital Trends Webinar”, we explored the powerful forces shaping Australia’s digital landscape. From AI acceleration and cybersecurity resilience, to the rapid evolution of data, cloud and human-centred design, one theme was unmistakably clear:
Women are breaking barriers across Australia’s digital transformation.
Across every sector, women are leading innovation, guiding strategy, strengthening resilience and championing the kind of inclusive, human-focused progress our industry needs. Yet, too often, their contributions go under-recognised, especially in the emerging and high-impact fields transforming our future.
That’s why we’re spotlighting the extraordinary leaders, builders, researchers, strategists and changemakers shaping Australia’s digital economy in 2026. Some are Women in Digital Award winners, others are rising leaders driving impact behind the scenes, but all represent the talent and vision powering Australia’s digital future. As we continue to navigate change and uncertainty together, these women remind us that leadership isn’t just about adapting to the future, it’s about shaping it.
