The Australian Government has legislated that channels 5 & 35 on the UHF CB Band are reserved for emergency use only
As at January 2007 the maximum penalties for the misuse of the legally allocated CB emergency channels are:
  • For general misuse – if an individual 2 years imprisonment, otherwise $165,000 (a $220 on-the-spot fine can be issued in minor cases); or
  • For interference to an Emergency call – if an individual 5 years imprisonment, otherwise $550,000 
If you interfere with another persons conversation just select another channel and do not provoke troublemakers that may deliberately search out other people provoke a reaction, Just ignore them remember
