The 26 GHz band is a mmWave band, harmonised for international mobile telecommunications (IMT) allocation at the World Radiocommunications Conference in 2019. This is a milestone towards international agreement on the band for 5G wireless broadband technologies.

In October 2019, the Minister for Communications, Cyber Safety and the Arts (now the Minister for Communications, Urban Infrastructure, Cities and the Arts) made the Radiocommunications (Spectrum Re-allocation – 26 GHz Band) Declaration 2019, declaring spectrum in the frequency range 25.1–27.5 GHz (the 26 GHz band) to be re-allocated by issuing spectrum licences.
