Gaypalani is the eldest daughter of renowned artist Wukun Waṉambi (1962–2022), whom she assisted as she was growing up. Their family home doubled as an art studio from her earliest years. The verandahs or the lounge room would invariably be the scene of art production, with a large pole or bark being worked on by her parents and siblings. Her father’s renditions of thousands of tiny fish demanded ultimate patience and precision. She carried much of the workload of assisting him, including grinding the ochre pigments.

​

Before her father’s sudden death in 2022, Gaypalani had begun to produce work in her own right and under her name with his blessing. By this time, her father had broadened his practice to include innovative digital work through the Mulka Project and was a member of the Found group of artists who engraved recycled road signs. After her father’s passing, cultural protocol required her to avoid using his designs. Instead, Gaypalani began to create artwork from the epic song poetry relating to the journeys of Wuyal, the Ancestral honey hunter.

Gaypalani was a 2023 Telstra NATSIAA finalist and in 2024 won the Ravenswood Women’s Art Prize. Her work is held in the collections of MAGNT, Parliament House (Canberra), Powerhouse (Sydney) and numerous private collections.
