One idea could be to purchase him a piece of artwork by an Aboriginal Australian artist. You can search for galleries or online stores that specialize in selling authentic pieces. Another option could be to get him a book on the history and culture of Aboriginal Australians or a cookbook featuring traditional Indigenous Australian recipes, allowing him to learn more about their culture and cuisine. Additionally, you could consider gifting him a didgeridoo, if he enjoys music and would like to learn how to play it.
Or you can get him a star map with the date when he was born.
