On Saturday, 27 March at 8:30 pm. local time, Earth Hour, an Australian-grown initiative and now one of the largest global grassroots movements for the environment, will bring people together for one hour to #SwitchOff lights and make the #SwitchforNature in a symbolic call for more action on climate change and to join the movement calling for a renewables future.

Set to be the most important Earth Hour yet, 2021 is a pivotal year for the planet.

In the wake of the catastrophic bushfires of 2019-20, Earth Hour is encouraging people to make the #SwitchforNature to support Australia’s switch to a renewables-based economy. Not only does Australia have some of the best renewable energy resources in the world, we now have our best ever opportunity to harness them for national and global good.

The impacts of the climate emergency were felt across the country and globe in 2019-20. Bushfires burnt an area bigger than Ireland, took the lives of at least 33 people and nearly 3 billion native animals were impacted. Beyond the fire-stricken areas, cities were shrouded in toxic smoke, droughts devastated farms and regional towns, the Great Barrier Reef showed signs of another mass coral bleaching event, and millions of people marched in capital cities around the world for stronger climate action.

“Australia’s biodiversity has taken an unprecedented hit during these devastating mega-fires. Our forests and wildlife can’t speak up or sign a petition, so we must do what’s right for the places and animals we love by calling on our governments to deliver immediate action on climate change,” said WWF-Australia CEO Dermot O’Gorman.

By combining what our nation is famous for, namely, – endless sunshine, huge land area, powerful winds, world-class expertise, and strong trade relationships – it’s a no-brainer Australia should take the lead as a renewable energy powerhouse.

By switching your individual actions, you can help change the future of our planet. Whether you switch to solar power, switch to a reusable coffee cup, or just switch off, you can support our planet by taking part in the world’s largest movement for the environment.


An estimated 5 million Australians (1 in 5) will participate on 27 March. Households, businesses and iconic Australian landmarks such as the Sydney Opera House and Sydney Harbour Bridge will turn off their lights for one hour during the event.
