Band details

700 MHz band : 703 MHz - 748 MHz paired with 759 MHz - 803 MHz

The 700MHz spectrum band supports mobile broadband services across Australia and suits to providing coverage over a wide area and with high in-building penetration.

2.5 MHz band: 2500MHz - 2690MHz

Spectrum in the 2.5 GHz band has high-data capacity in densely populated high demand areas and lower in-building penetration than the 700 MHz band.

2.5 GHz band: spectrum in the 2.5 GHz band has high-data capacity in densely populated high demand areas and lower in-building penetration than the 700 MHz band
Licence expiry

700 MHz band: commenced at 1 January 2015 for 15 years

2.5 GHz band: commenced on 1 October 2014 for a period of 15 years expiring on 30 September 2029 except for Perth metropolitan region and Western Australia region which commenced on 1 February 2016 for a period of 13 years and 8 months.

Allocation details

Type of allocation Price based allocation of spectrum licences under s60 of the Radiocommunications Act 1992 following declaration of encumbered spectrum for reallocation by spectrum licensing under s153B(1).
Method of Sale

Spectrum in the 700 MHz and 2.5 GHz band was allocated to new licensees using a combinatorial clock auction (CCA) format. The CCA consisted of two major stages over three rounds of bidding:  

an allocation stage (comprising clock rounds and a supplementary round), which determines the quantity of spectrum that each bidder secures

an assignment stage (comprising assignment rounds), which determines the specific frequency ranges awarded to each successful bidder from the allocation stage.  

Demand in the first round led to three unsold lots in the 700 MHz band. While demand for 2.5 GHz exceeded supply in the first round and reached equilibrium at the end of Clock Round 3.

Two auction design companies were engaged to conduct and verify the auction. Power Auctions a US based company experienced in the CCA format was engaged to provide an online auction system, expert advice and support to the ACMA for the auction. The Smith Institute based in the UK, who have extensive experience in supporting regulators that have auctioned spectrum using the CCA format, were engaged to verify the auction results and provide related services.

Competition Limits

Under the allocation limits, a single bidder could not acquire more than:

  • 2 x 25 MHz (50 MHz in total) in the 700 MHz band; and
  • 2 x 40 MHz (80 MHz in total) in the 2.5 GHz band

2.5 GHz band review



The last analog television broadcasting services were switched off across Australia at the end of 2013. One of the major benefits of digital television broadcasting is that it requires less spectrum than analog broadcasts even with the addition of extra digital channels. Australia’s switch to digital free-to-air television broadcasting involved services being retuned and stacked more efficiently into the broadcasting spectrum below 694 MHz. The cleared radiofrequency spectrum in the 700 MHz band is a dividend of the digital switchover. Regulatory and statutory changes enabled the ACMA to reallocate this ‘digital dividend’ to new licensees through a spectrum auction process.

In 2010 an extensive review of the 2.5 GHz band used for electronic news gathering (ENG) services recommended the ENG migrate to other frequencies (1980 to 2010 MHz and 2170 to 2200 MHz short to medium use spectrum) and the 2.5 GHz band frequency be reallocated for new uses, especially wireless communication services.

The Minister of the Department of Broadband, Communications and the Digital Economy directed the ACMA to set the reserve price in the 700 MHz band at $1.36/MHz/pop. In the 2.5 GHz band, the ACMA set the reserve price at $0.03/MHz/pop.

The ACMA made the decision to reallocate the released radiofrequency spectrum in 700 MHz and 2.5 GHz bands in a single auction. All the 2.5 GHz band spectrum sold at this auction. Whereas two 15 MHz in the 700 MHz band remained unsold. This spectrum was sold in the 700 MHz residual lots auction in 2017.
