Channel 0 is at 46.25MHz. I don't think it was part of the inital allocation when TV started as I've seen ads in 60s magazines for companies offering to convert tuners to receive the then new channel. Initially used by the ATV network before their move to channel 10, later used by SBS before they moved to UHF Channel 28. No longer used.
Channel 1 is at 57.25MHz. Usually used for the modulated output from VCRs, early game consoles and home computers. Channel 1 is as low as most modern tuners will go, some TV tuner cards can't quite make it. Used by the ABC network in some rural areas
Channel 2 is at 64.25MHz, used by the ABC network in capital cities.
Channel 3, 4 and 5 occupy 86.25MHz to 107.75MHz and are no longer in use. The allocation of these TV channels delayed the introduction of FM radio here. Some rural areas where channel 4 was used as an ABC repeater didn't have any FM radio until the repeaters were eventually moved to UHF in the 90s. This is also the reason the the "A" version Australian models of some 60/70s receivers (eg, Sansui 210A) are AM/SW rather than AM/FM.
Channel 5A is at 138.25MHz, I don't know when it was added. All the sets I've seen recently have had it, I don't remember if the older sets I've seen in the past had it. Still in use in some rural areas.
Channels 3, 4, 5 and 5A are oddballs that put us out of step with the rest of the world. Most VCRs and multisystem TVs can't tune them. Most imported european sets (Grundig, Normende, Luxor, etc) couldn't tune them.
When analog broadcasts are turned off there will be no TV at the lower end of the VHF bands.
Channels 6 to 9 occupy 175.25MHz to 201.75MHz. Digital broadcasts start at channel 6. Analog broadcasts are at channels 7 (HSV network) and 9 (GTV network) in capital cities, channel 8 in some rural areas.
Channel 9A at 203.25MHz has been allocated for digital TV.
Channels 10 to 12 occupy 209.25MHz to 228.75MHz. Channel 10 is used by the ATV network in capital cities. Channel 11 is used in various rural areas by different networks. Channel 12 is used for digital.
UHF is pretty standard with channels 21 to 69 from 478.25MHz to 819.75MHz.
When AMPS analog mobile phones were in use you could often hear them by tuning to the top of the UHF band. The continuous UHF tuners on some sets could get up a bit further than intended.
