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).
After working on the lower cards in Australia, Heffernan left his home country in 1953 and moved to America in the hopes of attaining more success there.
Costello mentioned his idea of an "Ultra Australian" tag team to fellow wrestler and future promoter, Joe Blanchard.
Costello and Heffernan made their debut as the Fabulous Kangaroos on 3 May 1957 for Stu Hart's Stampede Wrestling promotion in a match against Maurice LaPointe and Tony Baillargeon.
[1] After working in Stampede for a while, the Fabulous Kangaroos traveled across the United States, headlining shows wherever they went due to their ability to rile the crowd up with their heel (bad guy) tactics.
The fans began to throw fruit and stones after the match ended without a decisive winner, and the promoters had to step in, turn up the lights in the arena and play the National Anthem to stop a potential riot from breaking out.
Heffernan left Australia to tour the world and wanted to return to his homeland, while Costello was determined to remain in the United States at least for a while longer.
[1] Roy Heffernan returned to his native Australia and became one of the main wrestlers for World Championship Wrestling (WCW) (the Australian version) under promoter Jim Barnett.
