OT28: 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. https://thriveiaq.com/wp-content/uploads/2025/10/20250909-State-of-Indoor-Air-in-Australia-final.pdf The Air Quality Matters Podcast in Partnership with Zehnder Group - Farmwood - Eurovent- Aico - Aereco - Ultra Protect - The One Take Podcast in Partnership with SafeTraces and Inbiot Do check them out in the links and on the Air Quality Matters Website Chapters 00:00:00 Introduction: Australia's First Indoor Air Quality Baseline 00:01:35 The Shocking Data Gap: Less Than 0.03% Coverage 00:02:46 Geographic Blind Spots: The Queensland and Western Australia Concentration 00:03:45 Residential Findings: Gas Cookers, Wood Heaters, and Bushfire Smoke 00:04:27 The Hidden Dangers: Formaldehyde and Volatile Organic Compounds 00:05:06 Office Buildings: Traffic Proximity and HVAC Design Matter 00:05:37 The One Take: Documenting Our Ignorance as a Catalyst for Change 00:06:19 Critical Questions for the Future: Building Codes, Infiltration, and Protection 00:07:01 Closing: A Call to Action for Indoor Air Quality
