The Association of Apex Clubs of Australia is an Australia-wide association of autonomous clubs dedicated to fellowship, self-improvement, and community service, similar to other service clubs such as Lions International but with a younger membership (18–40). Apex organises a range of activities such as public speaking and debating competitions, ute musters, and B&S balls. Members call themselves "Apexians".

A ute muster is an Australian festival which brings together large numbers of utes and their owners. These events typically include competitions and other side events, occur annually, and normally last several days and are held in rural and regional areas of Australia and New Zealand.
