Call of the Running Tide Environmental Sculpture and Multimedia Festival is a biennial arts festival located in the Port Douglas area. Its aim is to respond to local, regional and global environmental issues. Jill Chism, a local, nationally renowned, environmental and public art practitioner, initiated the concept in 2017. Call of the Running Tide (CRT) supports the region's significant history of environmental activism.

The context of this body of work is the threatened ecology of the oceans, which frames the complex concerns and increasing awareness of the impact of climate change, rising sea levels, coastal development, over-fishing and ocean pollution and, specifically, plastic pollution.
