The Hero Defense League of Australia, or HDFL was a superhero team that was dedicated to protect Australia from harm.
The team was a government founded team of superbeings, created in 2016 in order to protect Australia from enemy threats during World War III. Most of the team went overseas to help combat enemy forces, while a few stayed behind to protect Australia. The team stayed together after the war.
Several members of the team were members of the Australian Defense Force, though others were not, having been recruited because of their skills. After joining however, they were registered as being members of the ADF, and were considered as such.
