Katrina Napaljarri Jingo was born in Alice Springs Hospital, the closest hospital to Mutijulu, a small Aboriginal community inside the boundary of the Uluru-Kata Tjuta National Park, in the shadow of Uluru. It is located 466 km south-west of Alice Springs in the NT of Australia. Her mother was originally from Papunya and her father from Alice Springs. Katrina grew up in Mutitjula and attended Yirara College, an Aboriginal boarding college in Alice Springs. When she finished school, she returned to Mutitjulu and worked for the Community Health Care. She also paints in her own community. She is married and has six children.
Katrina began painting with Warlukurlangu Artists Aboriginal Corporation, an Aboriginal owned and governed art centre located in Yuendumu in 2017 when visiting her cousin Jennifer Napaljarri Lewis. Jennifer lives in Nyirripi, originally an outstation of Yuendumu but now a small community, 160 km south west of Yuendumu. Katrina likes to paint Nguru Nyirripi wana (country around Nyirripi) with her cousin at the Nyirripi Art Centre, an outlet provided by Warlukurlangu.
When she is not painting, she spends time with her cousin, particularly when they go hunting out bush.
