The ACMA's Channel Finder

From 1 January 2015, wireless microphones must not be used in the 694 – 820 MHz frequency range. The main alternative frequency ranges will be 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.
