Before 2008, the 3.6 GHz band was mainly used by fixed point-to-point links and earth stations of the fixed satellite services (FSS). On 14 October 2008, the ACMA announced its intention to allow the use of the 3.6 GHz band to deploy site-based broadband wireless access services in regional and remote areas of Australia. These were authorised by apparatus licences. Capital cities, except for Hobart, were not included in the release to preserve future planning options within those areas.

Since that time, the band was considered under WRC-15 agenda 1.1, resulting in the 3600–3700 MHz band being identified for international mobile telecommunications (IMT) in Canada, Colombia, Costa Rica, and the US. The 3.6 GHz band also forms a subset of the 3300–3800 MHz band, which since 2016 has been recognised internationally as a pioneer band for 5G services. The standardisation of both non-standalone and standalone 5G equipment was completed by the 3GPP in June 2018. Several domestic and international operators commenced trials of 5G services. Europe, the US, China, Japan and Korea were also investigating or announced their intention to allocate all or some of the 3300–3800 MHz band for next generation fixed/mobile wireless broadband services.

The ACMA recognised that the 3.6 GHz band was being targeted as a pioneer band for 5G services internationally, and in October 2016 released a discussion paper on the future use of the band. A further options paper for the future use of the band was released in June 2017 for consultation. In October 2017, the ACMA released its decisions and preliminary views paper on the future use of the band and a draft spectrum reallocation recommendation that the Minister for Communications (the minister) declare that spectrum in the band be subject to reallocation by issuing spectrum licenses.

On 5 March 2018, following consideration of the ACMA’s recommendation, the minister made three spectrum reallocation declarations under section 153B of the Act. The ACMA then commenced preparing for and consulting on the allocation matters.
