RALIs to coordinate frequency

Radiocommunications assignment and licensing instructions (RALIs) ensure everyone uses spectrum effectively.


RALIs contain the rules to licence and coordinate frequency between services in a band. They help people avoid interference when they assign frequency. We develop them for:

  • accredited persons who assign or coordinate frequency
  • those who plan systems or sell equipment

The document below outlines our program of work to update our suite of frequency assignment and coordination rules. We are currently considering an updated review work program for 2023–24.
