Although not trained as a potter and never technically superior (his works, large and small, frequently exhibit cracking), the power of his vision of a modern Australia that embraces Aboriginal spirituality and respect for the natural world was his general message throughout his artworks.
From 1949 to 1960 he made frequent trips into Central Australia to live with Pitjantjatjara and Arrernte Aboriginal Australians, whose traditions and culture inspired his sculpture.
He left many of his central Australian works at Pitchi Richi near Alice Springs – a bird sanctuary run by his friend Leo Corbet – as he considered the landscape integral to these sculptures.
To many, including academics such as Marcia Langton, Bruno David and Mitchell Rolls, Ricketts is considered a controversial figure with his beliefs and his sculptures steeped in racism, exploitation and primitivism.
His trips to central Australia were viewed as controversial and filled with misunderstanding and tensions with Ricketts having incorrect preconceived notions of the roles of the Anangu people.
