BCV/GLV regional Vic, CTC southern NSW and TNQ Queensland. WIN own the NNSW NRN affiliate, and will probably hang out for a higher fee given how much they paid for it. Edit: or not…
It does get much more complex though - SCA half own all but one of the remaining joint-venture Ten channels, DTD Darwin, CDT Remote Central/East and TDT Tasmania, as well as fully owning SGS/SCN, but with complexities over separating that from the rest of the stations in the Spencer Gulf/Broken Hill market.
If they are in linear TV at all, they have to control their destiny. Leaving it up to affiliates as to if they are on the air is dangerous - and if they ever see a path forward to buying sports rights like NRL/AFL/Cricket, they can’t be in a situation where they have to explain to potential rights holders why they aren’t able to reach OTA viewers across the country.
Those sports rights are such a big component of Australian viewing habits - Ten/Paramount does pretty good without them, but not being able to be at the table would really hurt their chances of grabbing a share.
If the deal is Paramount buy it off SCA, or SCA Ten goes dark in unprofitable markets, you have to make the deal.
