In December 2017, ACMA auctioned the residual lots in the 1800 MHz, 2 GHz, 2.3 GHz, and 3.4 GHz bands (multiband residual lots). Five applicants (NBN Co Limited, Optus Mobile Pty Ltd, Telstra Corporation Limited, TPG Internet Pty Ltd, and Vodafone Hutchinson Australia Pty Limited) participated in the auction. The auction ran smoothly and resulted in all bidders securing spectrum.
Of the 39 lots available for allocation, 32 were sold, resulting in total revenue of approximately $92.6 million.
