IMPORTANT CHANGES TO THE USE OF WIRELESS MICROPHONES IN AUSTRALIA
From 1 January 2015, it became illegal to use any wireless microphones in the 694 – 820 MHz frequency range as those frequencies have been reassigned to Telecomunications.
Alternative frequencies have been assigned for general use and they include the following frequency ranges: 520 – 694 MHz and 1790 – 1800 MHz, with some other frequencies also available.
If you choose to use the spectrum in the 520 – 694 MHz range, you must not cause interference to television and radio services who also use this spectrum.
The ACMA’s regional fact sheets have high-level information about the changes to wireless microphones.
