Alicka  was born on the 9th May 1998, in Alice Springs Hospital, the closest hospital to Yuendumu, a remote Aboriginal community 290 km north-west of Alice Springs in the Northern Territory of Australia. She is the daughter of Maria Nampinjinpa Brown and Grand-daughter of Wendy Nungarrayi Brown, well-known artists in their own right. She has one sister Antoinette Napanangka Brown who also paints for Warlukurlangu Art Centre. Alicka comes from a long line of artists and has a good grounding in painting, watching her family paint and listening to her stories since she was a child.

She mainly paints her Grandmother’s Yanjirlpirri Jukurrpa (Star Dreaming) and her father’s Yarla Jukurrpa (Bush Potato Dreaming), stories that relate directly to the land, its features and the plants and animals that inhabit it. She began using traditional iconography but because of her love for pattern and colour she has developed an individualist style using pattern and design in a variety of contexts to depict her traditional jukurrpa.
