Channel Nein will show all finals FTA and live for 2013 as they have for the past few years.
Whenever FTA games are shown either live or delayed, such as the Friday night second game and Sunday games, Foxtel have a delayed telecast after the FTA telecast. It has something to do with contractual rights between the NRL, Nein and Foxtel.
The same goes for the major autumn and spring horse racing meetings. Channel 7 will show it live FTA and Sky Channel will have a audio broadcast simultaneously and vision a few minutes later.
Just checked the Foxtel guide but it isn't updated to mid September yet. Later in the month it should be available.
