Company Overview

The inspiration and story of the Widi Ngaruwa brand: Widi Ngaruwa means Black Duck in the language of the Wajarri people and tells the story of Robby Mallard and his journey and continued growth as an Aboriginal business owner. Through consultation with the Elders and Community, Robby was granted the use of these Wajarri words to represent our business. We pay our respect to Wajarri for this great privilege.

Our logo is a contemporary interpretation of an artwork created for Robby, by Yamatji woman, Loretta Egan. At the heart of the brand is the Black Duck – symbolic of vigilance, protection, balance, adaptation and strength. It is simplistic in its application and the design showcases movement. Widi Ngaruwa is in flight; powerful and commanding attention.

The three feathers in our logo are also a shout-out to our growth partner – Delta Group – and represent the enabling strength of our ally and friend in the achievement of business growth and the Widi Ngaruwa mission.
