What is Australia’s Most Identical about?

Nearly one in every 250 pregnancies in Australia results in identical twins, making them a valuable resource for our knowledge on genetics. But can some twins be more identical than others?

Over two big nights, Australia’s Most Identical seeks to answer this question by bringing together 100 sets of twins from diverse backgrounds and putting them through a fascinating series of tests and challenges, ranging from mind-boggling 3D facial scans, to tests of their creative capabilities, and more.
