In this work, Sabrina Robertson depicts the sacred site of Pirlinyarnu, located 165 km west of Yuendumu, which is linked to the Dreamtime story (Jukurrpa) of Water (Ngapa).

Legend has it that in the Dreamtime - the mythical time of creation for Aboriginal people - two rain-making ancestors from the Jangala family called down rain with their songs, triggering a huge storm. This storm merged with another storm and moved across various clan territories. It was then seized by a brown falcon ancestor (kirrkarlanji) who let it fall on Pirlinyarnu, where a very large swamp (maluri) formed. This swamp still exists today and when it rains, hundreds of ducks (ngapangarla) gather there.
