The Wurrungwuri sculpture is a bequest from the estate of the late Ronald Johnson in Sydney's Royal Botanic Gardens, overlooking Farm Cove. The sculpture resulted from the tireless efforts of his Trustees - Garry Boyce, Garry Clifford and David Gamson - over a period of eight years. The Trustees administered an International competition to select the artist before choosing Chris Booth.

Consisting of two parts, one made of 260 sandstone blocks in wave formation and weighing 350 tonnes, cascading towards Sydney Harbour. The other part is a monolith built from 16,000 threaded quartz pebbles and decorated with a pattern from a rare Aboriginal shield - the ''Sydney shield'' - after obtaining permission from Aboriginal elder Allen Madden on behalf of the Gadigal people.

The sculpture encourages native flora and fauna to take up residence and inside the woven quartz monolith are boxes in which small bats can roost.

Officially opened to the public by Her Excellency Professor Marie Bashir AC CVO, Governor of New South Wales on 9 March 2011, the Wurrungwuri sculpture makes a dramatic enhancement to its setting, responding to the forms of the landscape, the culture of the local indigenous people, and the natural flora and fauna of this sandstone country.
