The making of Australia’s first Dark Sky Community at Carrickalinga
In a world increasingly illuminated by artificial light, the beautiful night skies of a small coastal town in South Australia have attracted international recognition. Carrickalinga on the Fleurieu Peninsula is Australia’s first official Dark Sky Community. The title rewards a dedicated community effort to combat light pollution and preserve the natural environment at night.
The journey began three years ago when I was a PhD candidate at the Australian National University, working on the value of night skies. I was a regular visitor to Carrickalinga, but this time conversations at a picnic one evening turned to the clarity and brilliance of the stars. I was inspired to work with the locals to nominate Carrickalinga as a “Dark Sky Place”.
My recent research suggests restoring dark skies would be worth US$3.4 trillion(A$5.16 trillion) to the world, annually. That’s largely because light pollution is disrupting nocturnal pollinators, altering predator-prey interactions, and changing the behaviours of nocturnal species.
Light pollution has detrimental effects on wildlife, human health, and ecosystem functions and services. But there are simple solutions. By embracing responsible lighting practices, everyone can contribute to a healthier future in which the wonders of the night sky are accessible to all.
