Parley for the Oceans and adidas have reunited to build a full-size sustainable tennis court in the middle of Australia's Great Barrier Reef. Over the last several years, Australia as a whole has been severely impacted by climate change, with the increasing number of bushfires and coral bleaching of its reefs. The goal of the campaign is to raise awareness and start a discussion about how the world may rid itself of plastic waste.

The adidas x Parley tennis ball is crafted with yarn created from upcycled marine plastic debris and illegal deep-sea gillnets. These nets, usually used to illegally fish for tuna, are collected by Parley for the Oceans' partner organization Sea Shepherd, which then sends them to a spun-yarn maker in Switzerland to be made into the specialized tennis balls used in this installation.

The floating court is part of adidas's "Run for the Oceans" campaign, which encourages awareness for ocean health through public participation. The collaborative project aims to raise US$1 million in donations, with all proceeds going directly toward Parley for the Oceans' projects that will serve to clean up the world's oceans.

The court will remain open for play through November 2018, and adidas x Parley tennis balls manufactured from illegal deep-sea gillnets are available in Australia this month.

Adidas collaborated with the Great Barrier Reef Marine Park Authority (GBRMPA) to turn one of its floating barges into a tennis court surface on which four of the brand's top athletes played a match in the new Parley x adidas tennis gear inspired by colors of the reef.

The platform is covered in navy-on-white colors with the slogan "Plastic waste is a problem. Innovation is our answer," printed on the sides. After the campaign, adidas will donate the tennis court to a local school and convert the material into a sports court.Since 2015, adidas has worked with Parley to eliminate virgin polyester from all of its items by the end of 2025.
