The Great Indoors - Why Australia's First Indoor Air Report Changes Everything

Welcome back to *Air Quality Matters* and *One Take,* where we unpack the latest research shaping our understanding of indoor air and the built environment.

*The State of Indoor Air in Australia 2025,* produced by the Thrive Research Centre and key Australian institutions, represents the first real national stock take of indoor air quality in a country that has been measuring outdoor air for decades.

*The Shocking Reality:*
Australia has been producing national state of the environment reports for decades, but they have almost exclusively focused on outdoor air. The great indoors—where Australians spend 90% of their time—has been a massive blind spot. This document is the first real attempt to answer a very simple question: *What do we actually know about the air inside our buildings?*
The answer is a bit of a shock.

*The Big Takeaway:*
The most important finding of this report is not about specific pollution levels—*it's about the sheer vastness of what we don't know.* The report's great contribution is that it authoritatively documents our collective ignorance. It holds up a mirror and shows us a reflection that's mostly blank.
This report is intended as a baseline, a starting point, and a catalyst for a national conversation and hopefully a national strategy. After decades of focusing on the sky outside, it's time to finally pay serious, coordinated attention to the air in the rooms we actually live, work, and learn in.
This isn't just a report. It's the start of a very important piece of work.
