CB Emergency Channels
The Australian Government has legislated certain channels on the CB bands for emergency use only. The use of these channels for non-emergency communications can not only incur heavy penalties under the CBRS Class Licence and Radiocommunications Act, it could also cost someone their life if a call for help is missed due to interference.
The legally allocated emergency channels are:
- on the HF or 27MHz band - channel 9 (on 23 or 40chnl sets).
- on the UHF band, channels 5 and 35.

The UHF CB band used in Australia is unique to Australia and New Zealand. In Australia both channels 5 AND 35 have been legislated as emergency channels. Why? Very simply, channel 35 is used by repeaters operating on channel 5 as an input channel, so any transmissions on channel 35 can totally block any nearby channel 5/35 emergency repeater. In other regions, channel 35 is allocated for use as a secondary emergency channel.
Many people do not realise that UHF 35 is also an allocated emergency channel, and so they use it to chat between themselves potentially blocking any emergency call from being received on a repeater they probably don't even know exists! But an even bigger problem is the use of 5 and 35 by those totally unaware they even have a UHF CB. ALL of the now popular UHF hand-held units, sometimes called Communicators, FRS, Personal UHF Radio, or simply 40 channel UHF Radio, operate on the UHF CB band and are subject to these allocations. These sets are becoming more popular as toys for children, or for families to use to chat from car-to-car while travelling.
Emergency Repeater Locations
There are a number of repeaters operating on UHF 5 and 35 across Australia. These are licensed as Emergency Channel repeaters and are provided by a number of different organisations and businesses. To locate repeaters in any region of Australia visit the TropiNet website.
Some people claim that the emergency channels are not legally allocated by any government legislation, or are nothing more than a "gentlemans agreement" that does not need to be observed or can not be enforced. This is totally incorrect!
Since the legalisation of CB in Australia certain channels have been allocated for use for specific purposes. These were call channels and emergency channels, with road channels (commonly called truckies channel) legally recommended for such use. When individual licences were abolished these regulations were not removed, they were implemented into the Class Licence that automatically covers every person that uses a CB. The Radiocommunications (Citizens Band Radio Stations) Class Licence is federal legislation that replaces the need for each person or station to hold an individual licence, but it still governs how CB can and can not be used, and sets penalties for improper use. The Class Licence is made under the powers of the (federal) Radiocommunications Act 1992, and is enforced under that Act. The following is an extract from the Radiocommunications (Citizens Band Radio Stations) Class Licence 2002.
6 Conditions - generalA person must not:
(a) except in an emergency - operate a CB station on:
(i) carrier frequency 27.065 megahertz; or
(ii) carrier frequency 476.525 megahertz; or
(iii) carrier frequency 477.275 megahertz; or
Note: In an emergency mentioned in subsection 49 (1) of the Act, if a carrier frequency mentioned in this paragraph is not accessible, it is preferable that a carrier frequency mentioned in paragraph (b) should be used.
The frequencies referred to above are:
- 27.065 megahertz - HF CB Channel 9
- 476.525 megahertz - UHF CB Channel 5
- 477.275 megahertz - UHF CB Channel 35
For those that would like to read the text from the original source, you can view the legislation:
The ACMA define an emergency in the Radiocommunications (Interpretation) Determination 2000, Schedule 1:
Schedule 1 Dictionary
emergency signal means:
- a request for assistance; or
- a signal of distress; or
- a message that is related to a request for assistance or a signal of distress.
Operating in a manner that contravenes the conditions of the Class Licence is punishable under the Radiocommunications Act due to subsection 132, paragraph 3, of the Act, which specifies:
So, in essence, if you operate contrary to the provisions specified within the Class Licence, you could be liable to prosecution for operating an unlicensed radiocommunications device:
46 Unlicensed operation of radiocommunications devices(1) Subject to section 49, a person must not operate a radiocommunications device otherwise than as authorised by:
(a) a spectrum licence; or
(b) an apparatus licence; or
(c) a class licence.
(a) if the radiocommunications device is a radiocommunications transmitter:
(i) if the offender is an individual-imprisonment for 2 years; or
(ii) otherwise-1,500 penalty units; or
(b) if the radiocommunications device is not a radiocommunications transmitter-20 penalty units.
In January 2007 ACREM sought information from the ACMA on the current penalties for misuse of the emergency channels. The response from the ACMA advises that the following penalties can apply:
- For misuse of the emergency channels such as using for non-emergency purposes, the operator can be prosecuted for operating without a licence, as indicated above. Maximum penalty is 2 years imprisonment, or a fine of up to $165,000. Alternatively the ACMA can issue an infringement notice for an amount of $220 for minor offences.
- For interference to an emergency call in progress then section 193 of the Radiocommunications Act provides for a maximum penalty of 5 years imprisonment or $550,000. This offence can only be dealt with via court.
Section 193 of the Radiocommunications Act 1992:
193 Interference in relation to certain radiocommunications(1) Subject to section 196, a person must not, without the ACMA’s written permission, use a transmitter in a way that the person knows is likely to interfere substantially with radiocommunications carried on by or on behalf of:
(a) an organisation specified in the regulations that is:
(i) a fire fighting, civil defence or rescue organisation; or
(ii) an organisation providing ambulance services; or
(iii) any other organisation the sole or principal purpose of which is to secure the safety of persons during an emergency; or
(b) the Royal Flying Doctor Service; or
(c) the Australian Federal Police or the police force of a State or Territory.
(a) if the offender is an individual-imprisonment for 5 years; or
(b) otherwise-5,000 penalty units.
Our thanks to the NSW Regional Office of the ACMA for providing this information.
More information on this subject can be obtained from the federal agency that enforces the Class Licence and the Radiocommunications Act - the Australian Communications & Media Authority (ACMA). Although many people think that the ACMA don't care, ACREM has been involved in a number of instances where, following information provided by ACREM members, operators causing interference to the emergency channels have been located by ACMA field staff using Radio Direction Finding equipment and issued infringement notices or charged to appear before a court. Even mobile stations or those using low powered hand held equipment can be tracked and located, and a number of operators using this kind of equipment were located in late 2006 by ACMA staff in Brisbane and issued infringement notices due to their operation on the UHF emergency channels. ACREM continues to work with the ACMA to help keep these channels clear for their allocated use, in the interests of everyone's safety.
Throughout Australia there are various volunteer groups, like ACREM, that monitor the emergency channels relaying calls for assistance from the community to the required services.
In some country regions Police and other emergency services may also monitor and/or use UHF channel 5, however this is not guaranteed as circumstances vary from region to region.
Report Misuse of Emergency Channels
As part of our ongoing commitment to promoting the CB emergency channels, ACREM has embarked on a campaign to identify and educate businesses or government agencies using the emergency channels for routine communications. An example of the type of businesses already identified and contacted include:
- Traffic Controllers;
- Road Works crews;
- Cranes loading/unloading ships;
- Council workers.
If you know of a company, organisation or government agency that is incorrectly using the emergency channels, please help us to reduce interference by sending us the details. ACREM will contact the company/organisation/agency and provide information regarding the emergency channels and other legally allocated channels on the CB bands. You can use the Contact Form to send this information to us, or visit the Contact Directory to find the email addresses used.
Please make sure the following information is included in your message:
- The name of the company/organisation/agency;
- The location that operations were conducted from/to;
- The date(s) and time(s) that the transmissions occured;
- Any names or other forms of identification heard;
- Any other information that may be relevant.
Another ongoing campaign is to provide retailers with accurate information regarding the CB bands. With UHF CB equipment now being sold by discount stores, hardware stores, car spares stores, as well as electronics retailers, it is not surprising that some sales staff have limited knowledge about the CB emergency channels, or the entire Class Licence.
ACREM is seeking to identify retailers that provide incorrect information about the CB bands, so that we can send the retailer and, where appropriate, their head office, information for distribution to sales staff. Retailers of particular interest include those where sales staff advise:
- that there are no laws or regulations governing the use of CB in Australia;
- that you can use any channel you wish on CB bands;
- that there are absolutely no restrictions regarding channel uses;
- that the 'licence-free' UHF hand-helds are not CB;
- any other information that could cause a new user to misuse the emergency channels or other legally allocated channels.
If you have recently visited a retailer and have found that sales staff provide incorrect information about CB, please consider sending us the details. You can use the Contact Form to send a message to this programme, or visit the Contact Directory to find the email addresses used. The information you send should include:
- The name and address of the retailer;
- If possible, the name of the sales person spoken to (or a brief description);
- The date you visited the store;
- The information provided by the sales person.
How to call for Help
To call for help simply follow this procedure:
- Select the emergency channel on your CB - Channel
9 AM or USB on 27 MHz sets (channel 5 if it is an old 18 channel CB), or Channel
5 on the UHF Band (select 'Duplex' or 'Repeater' mode if in range of a channel
5/35 emergency repeater, otherwise use 'Simplex' mode - i.e. turn your Repeater
or Duplex button OFF).
In some country regions, emergency Monitors may monitor other local UHF repeaters in addition to, or instead of, the emergency repeater. If no response is received, try other local channels.
- Call “Any emergency monitor, this is (give your call-sign or first
name) calling any emergency monitor”
- Give the Monitor time to answer! If no response is received within 30 or so
seconds, call again.
- Respond with the nature of the incident, exact location and other
information. Don’t worry if you aren't sure what information to give, the
Monitor will ask you for the information that he/she needs in order to notify
the required services.
- IMPORTANT! Emergency Monitors can NOT offer first aid or medical
advice over the radio under any circumstances. If absolutely necessary, they
will contact the Ambulance Service or a Doctor and relay any advice they may
- There may be times when an Emergency Monitor is not available, or can not hear you. Atmospheric conditions can do very strange things to radio signals, and a local Monitor may not be able to hear your call above the level of interference being received at his/her location. If no one answers your call on the emergency channel, try other channels, especially UHF Channel 40 or HF Channel 8 (Road Channel) or other local repeaters (UHF Band).
REMEMBER! Emergency Monitors are volunteers often using their own radio equipment to listen for people needing help. It is impossible for any volunteer group to guarantee 100% coverage 24/7 without a large number of volunteers and funds. ACREM is constantly seeking new members and/or donations so they can expand operations and provide better coverage on the emergency channels, especially during major incidents. CB does save lives so if you have a CB at home and some spare time, no matter how little or how much, or even just a couple of dollars, why not help us to help you! Contact us for more information.
The CB Emergency Channels are not a replacement for 000! In Australia Triple Zero (000) is the primary emergency call service number - if you have access to a telephone you should use it to call for help rather than your CB. Calling for help using a telephone is very simple:
If you are using a mobile telephone you can also use the digital mobile emergency number of One One Two (112). This redirects to the Triple Zero (000) service but allows you to make contact as long as you have a signal from any mobile telephone provider (even if you have no signal from your own provider there may still be a signal from another provider that you aren’t aware of!). 112 also works even if you have no SIM card inserted or the SIM card is damaged. Many mobile telephone handsets will also bypass keypad lock once 112 is dialed (check your phone user manual and your service provider to confirm this number is available).
These days most mobile phones and networks offer the same enhanced service when you dial Triple Zero (000). Check with your phone user guide and your network provider to confirm if your phone will offer the same enhanced features when you dial Triple Zero (000).
Using the telephone to contact Triple Zero (000) allows you to speak with the required service directly rather than via a relay. This can save time if they need to ask you questions regarding the incident. So remember, if you have a telephone close by, and you can use it, then please contact the emergency services that way. However! If you do not have a telephone at hand, you have no phone coverage, you are unable to use the phone you have (e.g. can’t stop the car, etc), or you need to go and search for a public telephone, then please try the CB emergency channels immediately. The key to any emergency situation is to obtain help as quickly as possible, so if you have immediate access to a telephone use it, but if you don’t or can’t, then use your CB!
