Wireless microphones

If you use a wireless microphone you need to use the right frequency

Do not use the wrong frequency

If you use your wireless microphone on the wrong frequency you can interfere with other services such as TV reception. You can also disrupt the use of wireless audio devices that are using the frequency correctly.  

Use the right frequency

You should use your wireless microphone in the frequency ranges of 520 to 694 MHz and 1785 to 1800 MHz. There are more precise frequencies to use depending on where you are using your device.

You can no longer use wireless microphones in the frequency range of 694 to 820 MHz.

There is a group of frequency ranges located between 10 and 400 MHz used for wireless audio applications such as wireless intercoms, headsets in fast food outlets, hearing aids and toy microphones. Details can be found in items 1–21 in Schedule 1 of the low interference potential devices (LIPD) class licence

Frequency range (MHz)

Devices and services 

520 to 694

Television broadcasting services are the main users of this range. Wireless audio transmitters should only use the unused frequencies in this range.

Use our Channel Finder to find available frequencies in your area. Wireless microphones can use frequencies 520 to 526 MHz in all areas.

1785 to 1800

This frequency range is only for wireless microphone and other audio transmitter use. This frequency range is available in all areas.

174 to 230

This frequency range is available in many regional and remote areas. Use our Channel Finder to see if these frequencies are available in your area.

Any transmitter:

Digital transmitters: 
915 to 928 
2400 to 2483.5 
5725 to 5850

A wide variety of devices including wi-fi use these frequency ranges. Wireless microphones and audio transmitters can also use these frequencies. 


The 88 to 108 MHz frequency range is only for wireless audio transmitters and auditory assistance transmitters.

Your responsibilities

You should use your wireless microphone on the correct frequency for your location. If your device is using an unauthorised frequency, you should try to retune it or get help to fix the problem. 

Be careful when you buy wireless microphones from overseas sellers as other countries use different frequency ranges for these devices.

The rules for using wireless microphones

You don’t need to pay for a licence as the LIPD class licence lets you use a wireless microphone for free. We don’t manage the use of each device so it’s up to you to set your wireless microphone to the correct frequency and deal with any interference problems.

We may investigate cases of ongoing interference or serious misuse of wireless microphones. There are penalties if you deliberately break the rules or behave in a way that puts others at risk.

There is more information on the rules for using wireless microphones in the LIPD licence legislation.
