4G was introduced into Australia in 2011/2012 as the successor to the third generation network, known in short as 3G.
There are few major Australian Telecommunications Companies, otherwise known as telcos, which have the infrastructure supporting 4G; all other telcos, known as MNVOs, rent the infrastructure from them.
