Ngoia paints her father“’s country, which is a sacred Walpiri territory. The oval shapes in her paintings are an iconographic representation of the swamps and lakes near Nyrripi (Talarada) north west of Mount Liebig , approx 200kms west of Alice Springs. The finley detailed dots represent the water drying up and the cracks in the ground forming. This is where her father hunted prior to white settlement.
