Born at Lambina Station, near Marla SA, Sadie Singer was a strong leader and a pioneering woman on the APY Lands. Sadie Singer was them mother of six children, and also worked as a school teacher, as one of the first remote Aboriginal Health Workers, and the first female Police Aide on the APY Lands.

Mrs Singer established the Iwantja art centre in Indulkana Community, together with Alec Baker. In the early 1980s Mrs Singer and Alec Baker travelled from Indulkana to both Adelaide and Canberra in their campaign for government support to set up an art centre in their community, and Mrs Singer’s leadership and guidance was pivotal to the success of Iwantja Arts.

Mrs Singer was a renowned multidisciplinary artist, and was in particular an exceptional and prolific printmaker. A number of Mrs Singer’s prints are held in the collection of the Art Gallery of South Australia.

Mrs Singer’s artistic legacy continues with her daughters Priscilla Singer and Trisha Singer now painting at Iwantja Arts.
