World Oceans Day is celebrated on 8 June 2023. Each year on World Oceans Day we raise awareness about ending overfishing and protecting our oceans.


Why do we need World Oceans Day?

Our ocean needs protection.

  • Our ocean covers 70% of the planet and supports life as we know it
  • Every second breath we take comes from the ocean
  • Our ocean feeds billions of people
  • Our ocean hosts 80% of the world’s biodiversity.

However, our oceans are in crisis. They are being threatened by pollution such as abandoned fishing nets, overfishing, bycatch, and the effects of climate change.

We know the problems. We know the solutions.

World Oceans Day is a day to take action and raise awareness.

Whether you live beside the Indian Ocean or South Pacific, near the Coral Sea, Tasman Sea, or by the Great Australian Bight – there's no denying we're island nations who depend on the sea for food, jobs in fishing and tourism, recreation and lifestyle.
