In 2005, Telstra announced a plan to upgrade its ageing networks and systems; which includes a new 3G network to replace the then current CDMA mobile network.<ref>{{cite news |first=Iain |last=Ferguson |title=Telstra to slash tech costs under review |publisher=[[ZDNet]] |date=15 November 2005 |url=https://www.zdnet.com/home-and-office/networking/telstra-to-slash-tech-costs-under-review/ |access-date=30 April 2011 |url-status=live |archive-url=https://web.archive.org/web/20110404202138/http://www.zdnet.com.au/telstra-to-slash-tech-costs-under-review-139222399.htm |archive-date=4 April 2011 }}</ref><ref>{{cite news |first=Malcolm |last=Maiden |title=Telstra dives as $10bn plans unveiled |newspaper=[[The Age]] |date=16 November 2005 |url=http://www.theage.com.au/news/business/telstra-dives-as-10bn-plans-unveiled/2005/11/15/1132016797364.html |access-date=30 April 2011 |url-status=live |archive-url=https://web.archive.org/web/20121106175643/http://www.theage.com.au/news/business/telstra-dives-as-10bn-plans-unveiled/2005/11/15/1132016797364.html |archive-date=6 November 2012 }}</ref>

The network was built between November 2005 and September 2006, and launched in October 2006. {{As of|2007}}, Next G was the largest mobile network in Australia, providing greater coverage than other 3G providers in Australia and over three times greater than any 2G provider in Australia.<ref name="TheAge"/> In December 2008, the Next G Network was also the fastest mobile network in the World, delivering theoretical network speeds of up to 21&nbsp;Mbit/s{{Update after|2012|2|21}}
