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.

^Originally, the fourth episode of Between the Lines was due to be the final episode broadcast on 2 June 2011; the Nine Network then decided to air the sole remaining episode produced the following week on 9 June 2011, however, they reversed this decision screening the first part of Polar Bear: Spy on the Ice. The final episode is therefore yet to air.
