Safeguarding our starry skies for future generations

About Us
The Australasian Dark Sky Alliance (ADSA) began in 2019, inspired by a pivotal gathering of 100 delegates at Siding Spring Observatory – in Australia’s first dark sky place, the Warrumbungle National Park.
From that moment, a core group of volunteers came together to take action, tackling the growing threat of artificial light across Australasia.
Today, ADSA is an independent, not for profit organisation dedicated to reducing light pollution and preserving the night for people, wildlife, and future generations.
We unite communities, researchers, businesses, and policy makers to raise awareness, champion best practices, and save energy, money – and the stars.
"Did you know that globally, about 80% of the world’s population lives under light-polluted skies, and roughly one‑third of people can no longer see the Milky Way with the naked eye."

Enlighten, Educate and Empower
Light pollution affects everyone – but not everyone knows what it is. Learning about artificial light at night, its impacts, and how to reduce it empowers better choices at home, in business, and across communities.
Our Impact
ADSA is not just raising awareness - we’re building a coordinated, evidence-based response to one of the fastest-growing forms of environmental pollution.
Key Achievements
ADSA’s partnership with ABC Science for National Science Week 2024 led a dark sky campaign with 45 media interviews. Public events, including a Guinness World Record webinar, engaged 15,000 people from 76 countries. The Valuing Darkness Symposium gathered 210 delegates from councils and conservation groups.
ADSA’s network grew tenfold, and it continues supporting Australia’s Dark Sky Legacy by assisting certified Dark Sky Places and developing lighting now in the Sunshine Coast Council’s plan. ADSA fosters collaborations with councils, conservation groups, and federal departments.
