One idea could be to get your grandma a piece of Aboriginal Australian artwork. There are many beautiful pieces available online or in art shops. Alternatively, you could also get her a book about Aboriginal culture, history, or art. Another idea could be to buy her a traditional didgeridoo, which is a wind instrument commonly used in Aboriginal music. She could learn to play it or simply use it as a decorative piece in her home.
Or you can get her a star map with an important date you share.
