Can I use Yulunga games as skill or lead-up games in PE lessons?

Yes. The resource says many of the games can be played successfully as skill games or lead-up games in physical education lessons, or in specific sports practice sessions, rather than as major games in themselves. A large number can also be played as outlined in the book. Some types, such as wrestling and ball games, offer the chance to play different versions, and the games vary in the type and level of competition. The introduction describes them as primarily a contribution towards implementing Indigenous Australian perspectives across the education curriculum from Kindergarten to Year 12.
