To help stamp out trachoma, you can donate to Fred Hollows Foundation to treat it directly or donate to a charity that helps communities emerge from poverty and break the cycle of infection and re-infection.

Despite High Income, Australia Faces Neglected Tropical Diseases
The number of people in Australia requiring intervention against Neglected Tropical Diseases has come down.
Line chart of numbers over time from 2010 to 2022 with a spike in 2013. 2010: 89,732; 2011: 72,560; 2012: 60,279; 2013: 144,692; 2014: 54,311; 2015: 17,476; 2016: 20,994; 2017: 20,123; 2018: 20,123; 2019: 13,700; 2020: 20,401; 2021: 18,286; 2022: 3,477

What Are Neglected Tropical Diseases (NTDs)?
Neglected tropical diseases are a group of conditions caused by viruses, bacteria, parasites, fungi and toxins, and can cause significant disfigurement, disability, and death.
They include preventable and treatable diseases that affect more than 1 billion people globally, especially impoverished communities in tropical regions.
These diseases are “neglected” because they’re barely present on the global health agenda. Limited resources are dedicated to tackling them.

The World Health Organization's List of Neglected Tropical Diseases: Buruli ulcer; Chagas disease; dengue and chikungunya; dracunculiasis; echinococcosis; foodborne trematodiases; human African trypanosomiasis; leishmaniasis; leprosy; lymphatic filariasis; mycetoma, chromoblastomycosis and other deep mycoses; noma; onchocerciasis; rabies; scabies and other ectoparasitoses; schistosomiasis; soil-transmitted helminthiases; snakebite envenoming; taeniasis/cysticercosis; trachoma; yaws

Have We Eliminated Trachoma in Australia?
Trachoma is a preventable eye infection that can lead to blindness. Australia's the only high-income country that has trachoma.
A couple of years ago, we reached the World Health Organization's threshold for “elimination as a public health problem”. The prevalence is really low now. So long as our trend of squashing it continues, we'll be able to declare it eliminated.
2025 could be the year!

For Day 23 of the #30DayChartChallenge, the prompt is "Log scale"

(Technically, this isn't actually a log scale but I wanted to play around with the idea of giving the more recent, more densely located data points more space)

A line and scatter plot showing the income share of the richest 1% from 1800 to 2020. It highlights sparse data in the 19th century, a sharp decline and rise across the 20th, and relative stability in the 21st. Different colours mark each period's trend.

These days you can look up air quality for a bunch of places, but those numbers won't help you with your cooking.

https://apps.des.qld.gov.au/air-quality/

Total Dust Emissions Across Australia
Airborne soil particles are worse in summer where ground is dry and there's less vegetation cover compared to winter.
A grouped bar chart of amount of dust in tonnes per hectare to June 2020 grouped by Emission, Dry deposition, and Wet deposition shows the highest emissions from Nov to Jan around 3k tonnes per hectare. Dry depositions are also much higher than wet depositions.
Data: Emmerson KM & Keywood MD (2021). Australia state of the environment 2021: air quality, © Commonwealth of Australia, CC BY 4.0, https://soe.dcceew.gov.au/
Chart: @DiDoesDigital

Dust Travels Everywhere
From July 2019 to June 2020, the estimated total dust emissions in Australia was 40 tonnes per hectare.
Dust that's swept into the atmosphere ranges from smaller than 2.5 micrometres to hundreds of micrometres.
The larger particles cause visibility issues and filthy solar panels. They “deposit” onto the ground swiftly, meaning they don't get to travel far.
The smaller particles, however, stay in the air longer and can waft thousands of kilometres onto cities far away.

Dust Can Be Gross
Airborne dust can muck up your respiratory system. Mineral dust contains metals like iron that cause lung inflammation.
Thanks to the extra droughts and bushfires from climate change, we’re likely to see an increase in the number of dust days too.
Vegetation programs might help keep the dust down.
Australia generally has great air quality, except during specific events like dust storms and bushfires. There’s increasing demand for real-time air monitoring to help people know when to close the windows or mask up.

Try a Low-Cost Sensor
More of the public are buying low-cost air sensors. They’re not super accurate but they can give you an idea about trends or when your over-cooked pancakes are hazardous.

For Day 22 of the #30DayChartChallenge and the prompt of "Stars", I found it quite tricky to make the income inequality data I've been working with fit the prompt.

Is it a radar chart?
Is it a star?
Is it a constellation?

I don't know whether I love it or hate it , but either way it's made with #RStats! For reference, the inner 'stars' represent 1%.

Down under, you can use the Southern Cross to tell time and direction.

Aboriginal Australians are among the world's first astronomers. The southern cross forms part of the Emu in the Sky, a dark constellation, which has featured in storytelling for thousands of years.

Find South Using the Stars
In the southern hemisphere, you can use the Southern Cross (aka “Crux”) and The Pointers constellations to find South.
The chart of the Southern Cross and The Pointers shows a line drawn from the highest star of the cross, Gracux, through the lowest star of the cross, Acrux, and another line drawn perpendicular from Alpha Centauri and Beta Centauri, and the two lines marked as roughly south, not far from where the South Pole is marked.
Chart: @DiDoesDigital

Check the Star Clock: Part 1
Imagine a 24-hour clock face. Around 1st April, Crux appears high in the sky at midnight. At the 20 hour mark, it's ~8pm.
The 24-hour clock face has 0 at the top, labelled (midnight), 6 to the right, 12 at the bottom, labelled (midday), and 18 to the left. The Southern Cross constellation is positioned at the 20 hour mark with repeating, fading copies of it clockwise indicating the direction of travel. The chart is labelled 1st April 8pm.
Chart: @DiDoesDigital

Check the Star Clock: Part 2
For each month after April, take 2 hours. At 1st May, if Crux is at the “20” mark, subtract 1 month × 2 hours to get 18: ~6pm.
The 24-hour clock face has 0 at the top, labelled, 6 to the right, 12 at the bottom, and 18 to the left. The Southern Cross constellation is positioned at the 20 hour mark. An arrow points anti-clockwise, labelled "Subtract 2 hours". The chart is labelled 1st May 6pm.
Chart: @DiDoesDigital

You Can Find South and the Time!
Around 1st June, when Crux appears at the “6” hour mark, subtract 2 months × 2 hours to get 2, which means it’s ~2am.
The 24-hour clock face has 0 at the top, labelled, 6 to the right, 12 at the bottom, and 18 to the left. The Southern Cross constellation is positioned at the 6 hour mark. An arrow points anti-clockwise, labelled "Subtract 4 hours". The chart is labelled 1st June 2am.

Are you also pleased to know that the Tassie geo database has 97 results for "fossiliferous"?

This shows the number of listed geosites in the Tasmanian Geoconservation Database by era.
Bar chart of sites by era from Oldest first. Mesoproterozoic: 7; Neoproterozoic: 43; Paleozoic: 249; Mesozoic: 66; Cenozoic: 748; and Unknown: 14.

Our Geological Heritage is Precious
Geoheritage helps define Australia through its iconic landscape. Our geoheritage has significant aesthetic, cultural, economic/tourism, and environmental value. It also informs our future climate.
Like biodiversity, geoheritage is a form of natural heritage but benefits from separate recognition. For example, it requires different conservation strategies to plants and animals.
Australia has an old and stable land mass, so we have heaps of preserved geological features rarely found elsewhere.
McConnell A, Janke T, Cumpston Z & Cresswell I (2021). Australia state of the environment 2021: heritage, independent report to the Australian Government Minister for the Environment, Commonwealth of Australia, Canberra, DOI: 10.26194/7w85-3w50.

Tasmania Has Special Old Rocks
Tasmania is a global geodiversity hotspot with rocks of every geological period from the Mesoproterozoic.
Unlike most of Australia, Tasmania keeps a nice record of geoconservation sites. You can find info about:
- 39 globally significant sites
- 26 rarities
- 32 outstanding references
Entries in the Tasmanian Geoconservation Database also include the geoconservation values the sites encompass, their significance to conservation, their sensitivity to disturbance, and advice on site management.
Data: Natural Values Atlas (www.naturalvaluesatlas.tas.gov.au), 21 Apr 2025, © State of Tasmania · Analysis: @DiDoesDigital

Can We Protect Our Geoheritage?
The pressures having the greatest impact on geoheritage include:
- “Inadequate resourcing for heritage conservation/management.”
- “Inadequate protections (poor statutory controls and poor governance)”
The highest priority action to improve the management of geoheritage is:
- “Improved recognition, including at the statutory level, and moving beyond land-based-only heritage”
Vote for representatives who pledge conservation action.

Given the year we've had, I don't have high hopes that Australia's press freedom index ranking will improve next month. Let's make some changes!

Australia's Press Freedom is Bordering on Problematic
The World Press Freedom Index shows Australia's score is declining (0 is worst, 100 is best).
The line chart shows the score from 2014 to 2024. The scores are: 2024: 73.42; 2023: 78.24; 2022: 73.77; 2021: 80.21; 2020: 79.79; 2019: 83.45; 2018: 84.54; 2017: 83.98; 2016: 82.16; 2015: 82.97; and 2014: 83.09. The "problematic" range of 55–70 is shown. An arrow points to the recent "satisfactory" scores just above problematic.
Note: The methodology changed in 2022. Data: Reporters Sans Frontieres (2025).

The World Press Freedom Index Compares the Level of Freedom for Journalists and Media Globally
"Press freedom is defined as the ability of journalists as individuals and collectives to select, produce, and disseminate news in the public interest independent of political, economic, legal, and social interference and in the absence of threats to their physical and mental safety."
