In 2023, the British Council for Offices (BCO) updated the ventilation guidance for offices:
💨 The *minimum* recommended ventilation rate was increased from 12 to 14 litres of outdoor air per sec per person.
Now guess what the ventilation rate is in a typical UK classroom…❓

UK research reveals indoor CO₂ >1,000 ppm impairs cognition: 15% worse word recognition in schools, 7% slower math speed, 2.2% longer reaction times. Bedroom spikes to 2,395 ppm vs. 835 ppm cut next-day logical thinking by 3%. Stuffy air leads to foggy brain. Full findings here: venti-group.com/docs/what-is…

A Public health department FINALLY produced a video explaining how airborne viruses work. Next step, getting videos like this on TV and all over social media. Too many people think handwashing will prevent covid or the flu🫤

The NHMRC yesterday announced final allocations for the year. The 2025 success rate for Ideas grants was 10%, Investigator grants 13%, and Clinical Trials 9%.
Australia's total spend on healthcare and technology innovation in medicine and biotech from the Medical Research Endowment Account and Medical Research Future Fund this year will equate to the cost of 0.004 submarines.
We're spending more on a single submarine than we'll spend on medical research in 30 years.
Medical research matters. A clever country invests in the things that matter.

When Addenbrooke’s Hospital in Cambridge upgraded its face masks for staff working on COVID-19 wards to filtering face piece 3 (FFP3) respirators, it saw a dramatic fall – up to 100% – in hospital-acquired SARS-CoV-2 infections among these staff. 👇 cam.ac.uk/research/news/upgr…

Why I Still Mask
I still wear a mask. Not because I’m paranoid, not because I’m weak, but because I understand that the air we share carries risk. COVID-19 has not gone away. It’s still disabling people, it’s still taking lives, and it still spreads silently. Pretending otherwise doesn’t make me brave—it makes me careless.
Masking is a simple act of self-respect and respect for others. I don’t know who I might be sitting next to on a bus or standing behind in a shop queue. Maybe they’re recovering from surgery, maybe they’re caring for an immunocompromised child, maybe they’re just hoping they won’t get sick before payday. I choose to do the small thing that helps protect them as well as myself.
There are people who sneer, roll their eyes, or make comments. They think intimidation or mockery will get me to fall in line with their comfort zone. But I won’t. Why should I be pressured into gambling with my health—or theirs—just to fit in? The truth is, taking off the mask doesn’t make the virus go away. It just makes people feel less uncomfortable about their own choice not to protect themselves.
I won’t be shamed into ignoring reality. My health matters. The health of strangers matters. Science is clear: masks reduce transmission. I’d rather stand out for doing something protective than blend in while putting myself and others at unnecessary risk.
So yes, I’ll keep masking. Not out of fear, but out of responsibility. And no amount of smirks or side-comments will change that.

The success rate for NHMRC Ideas Grants announced yesterday was just over 8%. That means 11 of every 12 people who applied got rejected. This is a culture changing level of rejection and frankly a point of national shame. The Federal Government needs to take urgent action. This is a crisis for research.
As the CEO of the Australian Society for Medical Research I will not rest until we see this resolved.

72% of Australians support a total ban on gambling ads.
It’s been 881 days since the Murphy Report recommended that Parliament ban gambling advertising.
30% of Australian children aged 12 to 17 gamble - they lose nearly $20 million every year.
Backbenchers agree, but the govt's refusing to act.
We need a conscience vote on gambling ads.

Here’s the sober reality, and it dwarfs any fantasy about “asbestos in wind turbines” by several orders of magnitude.
Australia isn’t dealing with a few grams of asbestos in imported brake pads.
We are dealing with millions of tonnes of asbestos left across the continent from a century of mining, construction, and industrial use.
Here are the key facts, drawn from the Australian Asbestos Safety and Eradication Agency (ASEA), state health authorities, and historical mining records.
⸻
THE REAL ASBESTOS RISK IN AUSTRALIA: MILLIONS OF TONNES FROM MINING, NOT RENEWABLE ENERGY
1. WA’s Wittenoom (blue asbestos): 3 million tonnes of tailings
Wittenoom Gorge was once the largest crocidolite (blue asbestos) mine in the world.
•3 million tonnes of asbestos-laden tailings dumped across the landscape
•Tailings used as road base, building fill, and even playground surfaces
•Townsite now contaminated across hundreds of hectares
•WA government still removing families and demolishing structures into the 2020s
•Thousands of workers and residents dead or sick
This is the largest contaminated site in the Southern Hemisphere.
Nothing in renewable energy comes remotely close.
⸻
2. NSW’s Baryulgil (white asbestos): contaminated soils + community health crisis
James Hardie operated the Baryulgil chrysotile mine for decades.
•Tailings used for roads, yards, community areas
•Chronic mesothelioma cluster among Bundjalung families
•Asbestos present in soil, drainage, and building materials
Again: actual, widespread environmental contamination.
⸻
3. Queensland asbestos mines: widespread diffuse contamination
QLD had several dozen chrysotile mining and milling sites.
•Contaminated pits
•Abandoned mine waste
•Residual fibres in soils
•Remediation still ongoing at multiple sites
These are real contamination sites, not hypothetical.
⸻
4. South Australia: Woodsreef (near Barraba)
One of Australia’s largest asbestos dumps.
•25 million tonnes of asbestos-containing waste rock
•Piles up to 70 metres high
•Fibres still blowing in dry conditions
•Ongoing state monitoring since the 1990s
This alone makes the “asbestos in a lift brake pad” story laughable.
⸻
5. Building legacy: 6,000+ products, millions of homes
Between 1940 and 1990 Australia imported and manufactured over 1 million tonnes of asbestos-containing materials.
This includes:
•fibro sheeting
•lagging
•insulation
•adhesives
•concrete pipes
•roofing
•brake pads
•cladding
•gaskets
•vinyl tiles
•electrical boards
ASEA estimates:
•1 in 3 Australian homes contains asbestos
•Many schools, hospitals, sheds, garages, and outbuildings still contain it
This is the real asbestos burden.
⸻
TOTAL ESTIMATE: Tens of millions of tonnes of asbestos-containing waste remain across Australia
Between abandoned mines, contaminated soils, industrial tailings, and asbestos-containing building materials, Australia is dealing with:
➡️ 20–40 million tonnes of legacy asbestos-containing material
➡️ Millions of contaminated sites
➡️ Hundreds of thousands of affected structures
Compare that to:
•a few grams of bonded asbestos inside lift brake pads in sealed machinery at a handful of wind farms.
It’s not even in the same universe.
⸻
THE LINE THAT CUTS THROUGH THE HYSTERIA
Australia has millions of tonnes of asbestos scattered across old mine sites, tailings dumps, roads, yards, and 1 in 3 homes — yet anti-renewables activists want you to panic about a few enclosed brake pads inside sealed tower lifts. It’s theatre, not public health.

Smart countries don’t cut funding to their world-leading science and technology research organisations.
The Albanese government has to step up and provide adequate support for research and development in Australia - it has to invest in our future. abc.net.au/news/2025-11-18/c…

100's of jobs cut at CSIRO when it has never been more important for govts to invest in science & research. Why can Labor find $$ for AUKUS but not our nation’s premier science, industry & research org? The Greens implore the Albanese government to commit funding & prevent cuts.
Rachel Uren retweeted
It’s not merely @CSIRO that’s in trouble in research. Medical research @AAMRI_Aus & Universities is unsustainable with institutes facing same issues or worse as @CSIRO. Govt must release the full MRFF yield of 1.1bn pa & stop shortchanging medical researchers & our community

School attendance has, once again, been a hot topic of debate these last few weeks.
Last week, we had some schools publicly sharing their attendance campaigns on social media.
This week, we've had the Government announcing the dawn of AI generated attendance targets.

The "airborne airborne and airborne" are for colds, flu and the infection that must not be named.
If you inhale virus - its airborne!

Check out this handy guide to find out when your child should stay off, and when they can go back to school if they are well enough to do so.
If your child is unwell and you have concerns about their symptoms you should speak to your GP.

Today we’re in Canberra standing with @Mon4Kooyong and the research sector to call for urgent action to unlock the full $1 billion MRFF.
Half the funding means half the future.
