"The Citizen Band Radio Service (CBRS) is a twoway, short distance, voice communications service that can be used by any person in Australia. CB
radios provide a cheap and reliable means of communications.
The service operates in two distinct frequency bands—
the high frequency (HF) band (26.965–27.405 MHz)
and the ultra high frequency (UHF) band (476.425–477.400 MHz)."
Anyone can use any frequency with the following exceptions.
"There are specific calling channels in the two CB
bands. Channel 11 (AM – 27.085 MHz) and
channel 16 (SSB – 27.155 MHz) are the calling
channels in the HF band and channel 11 (476.675
MHz) in the UHF band.
Once you have established contact with another
traveller, switch to another channel to continue
talking."
"Data can only be transmitted on UHF
channels 22 (476.950 MHz) and 23 (476.975 MHz),"
"channel 9 (27.065 MHz) in the HF band
and channel 5/35 (476.525/477.275 MHz) in the
UHF band.
These channels are designated as emergency
channels and non-urgent traffic must be confined to
other channels."
"Channels 5 and 35 are dedicated for emergency
communications ONLY."
