In 2025, we are embracing the theme of 'Evolution, Insights, Into Impacts' a concept at the heart of our profession as occupational hygienists, in the beautiful city of Sydney, New South Wales.

Since AIOH21, our themes - Challenge for Change, Simple Sustainable Solutions, Future Ready, and Scientific Storytelling - have all pointed to one word: Evolution. AIOH25 explores the ongoing evolution of occupational hygiene and the challenges shaping our industry.

Post 2020, changes have placed occupational hygienists in greater demand than ever. Driven by legislative updates, technological advances, rising workplace expectations, and a world-class commitment to progress, it's an exciting time for our profession.

But key questions remain: Have we done enough? Are we truly future-ready? Are we guiding the next generation? What insights can we provide to make meaningful impacts?

AIOH25 will explore:

The next generation of occupational hygienists - how we promote, train, and inspire
Insights, the changes in legislation and what impact it is having
New sampling methodologies and cutting-edge technologies
How we continue to anticipate, recognise, evaluate, and control
And most importantly: Are we there yet, or is there still more to do?

Join us as we define the next phase in the evolution of our profession at AIOH25.
