Laurence Roy Heffernan (12 July 1925 – 24 September 1992) was an Australian professional wrestler. Roy Heffernan toured all over the world, but is most famous for being one half of the original version of the tag team the Fabulous Kangaroos (with Al Costello). The Kangaroos used an "Ultra Australian" gimmick complete with Boomerangs, bush hats and "Waltzing Matilda" as their entrance music. The first incarnation of the Kangaroos is the most famous of all the Kangaroo versions and is often credited with popularizing tag team wrestling in the late 1950s and 1960s. Costello and Heffernan are also regarded as one of the top tag teams to ever compete in professional wrestling.
