Karra was a visual arts project devised for the 2000 Adelaide Festival. Its focus was the River Red Gum, once the most widespread tree in south eastern Australia and quite justifiably an Australian icon. The project comprised an installation by three artists Chris De Rosa, Agnes Love and Jo Crawford in the Artspace Gallery, Adelaide Festival Centre, from 1 March to 20 April, and a 40 page publication with essays and visual material from many contributors. As curator, Thwaites' intention for Karra was for people to consider their connection with the tree as well as the urgent problems facing this ecosystem, such as salinity, diminished water flow and environmental degradation.
