World Oceans Day is celebrated on 8 June 2024. 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.

Even though World Oceans Day is a global day to celebrate our oceans, there's plenty that can be done locally to support ocean life around our coasts. 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.

The history and significance of World Ocean Day

The history of World Oceans Day dates back to the early 1990s.

The concept of a dedicated day to honour the world's oceans was first proposed by the Canadian government during the Earth Summit held in Rio de Janeiro, Brazil, in 1992. The Canadian government suggested the idea of establishing an international day to celebrate the oceans and their significance in our daily lives.

The proposal gained support from various organisations and governments around the world, and in 2002, World Oceans Day was officially recognised by the United Nations General Assembly. The United Nations Division for Ocean Affairs and the Law of the Sea (DOALOS) was designated as the focal point for coordinating and promoting the observance of World Oceans Day.

Since its official recognition, World Oceans Day has been celebrated globally with a wide range of activities and events. These activities include educational programs, beach clean-ups, art contests, film screenings, public lectures, and other initiatives aimed at raising awareness about the vital role oceans play in sustaining life on Earth and the need to protect and conserve marine ecosystems.

World Oceans Day provides an opportunity for individuals, communities, and organisations to come together and emphasise the importance of ocean conservation and sustainable practices. It serves as a platform to highlight the various threats facing the oceans, such as pollution, overfishing, habitat destruction, and climate change while promoting solutions and encouraging collective action to address these challenges.

Through the years, World Oceans Day has grown into a global movement involving millions of people across the globe who are committed to protecting our oceans and ensuring their long-term health and vitality. The day serves as a reminder of the interconnectedness of all life on Earth and the need for sustainable practices to safeguard our oceans for future generations.
