This is a list of programs which made their premiere on an Australian television network that had previously premiered on another Australian television network. The networks involved in the switch of allegiances are predominantly both free-to-air networks or both subscription television networks. Programs that have their free-to-air/subscription television premiere, after previously premiering on the opposite platform (free-to air to subscription/subscription to free-to air) are not included. In some cases, programs may still air on the original television network. This occurs predominantly with programs shared between subscription television networks.
