Was browsing ExplorOz whilst Googling for UHF radios and came across this- which I found very interesting! I honestly had no idea it was against the law to speak on some channels.

Below you will find a list of UHF Radio channel allocations. There are many channels that have been established by law including the Emergency channel 5 and the data transmission channels 22 and 23.
- 1 to 8 - These channels, which are established by law, can be used when sending a signal to a repeater which will help increase the communication distance
