Sonia was born by a billabong at Noonkanbah community. Her parents were Walmajarri whose movements led them to live by the Fitzroy River. Sonia has lived most her life at Noonkanbah. A compulsive artist, Sonia for a long time was a teacher's aid at the local school where she facilitated art making with the children. Illustrative of her attachment to the country where she grew up, an intimate life with the river, Sonia's art is a saturation of river country motifs, be it parlka (barramundi), brim, tortoise, stingray, pandanus trees or the water itself.
"Martuwarra is my river country; this painting is all about the Fitzroy River which flows down through Noonkanbah where I live. All kinds of fish live in the water, we catch big mob of fish here. I like Parlka (barramundi). We catch catfish and brim here too. Nganku (shark), Wirritunany (sawfish) and Stingray also live here. These fish live in these waters long after the flood has gone. Also this painting is about barramundi swimming on the surface of the water, you can also see the Wakiri (pandanus tree) and rocks all around. When the barramundi get tired they go back into the rock holes. These rock holes hold all the Parlka (barramundi) that live in the river. Kalpurtu (creator serpent-type being) also live in these rock holes and swim all around the Palma (creeks) and all around the Wakiri that grows in the river."
