The history of Australian TV is fascinating. It's the only major country I can think of where commercial and government TV were both created simultaneously - at the dawn of TV there in 1956, the biggest cities each had two commercial operators and ABC.
The modern Seven, Nine and Ten networks accreted gradually, starting with informal connections between the big-city commercial stations and eventually adding affiliations with smaller independent stations around the country.
In the last 25 years or so, it's turned into a mirror of Canada: each of the commercial networks ended up owning its stations in the big cities (Sydney, Melbourne, Adelaide, Perth) and in some cases the rural affiliates as well, so most of the old local brandings went away and everything is "Seven Darwin" or "Nine Canberra." There's local news in the big cities and not much else local left out there.
And the channel assignments are strange, too - there was the old channel 0 (which largely got moved to 10), plus the weirdness of channel 5A.
It's still a little unusual on a global level in that a lot of the DTV transmitters are on high-VHF (which starts on channel 6 there) instead of being exclusively UHF.
I'd love to do some tower hunting there!
I'm assuming that with the advent of digital, the affiliates of the respective "number networks" have PSIP mapping to the appropriate channel number, such that all Seven affiliates, regardless of OTA channel, show up as PSIP 7, Nine as PSIP 9, and so on. Is that the case?
I'm also assuming that they do have PSIP in Australia.
