As, more Australians are ditching their fixed-line home phones for a mobile-only existence, according to the Australian Communications and Media Authority (ACMA).
The data for the ACMA research snapshot was collected up until December 2012, so the numbers could actually be higher now.
Even fixed-line internet is seeing a decline. Out of the 3.3 million people who used their mobile as a home phone substitute, 54 percent of them went online using their mobile phone, a 17 percent jump from the previous corresponding period.
But even so, only 3 percent of the population, around 482,000 completely substituted fixed-line home phone and internet services with their mobiles.
Younger people, aged between 25 and 34, and those who lived in metropolitan areas, were more likely to be mobile-only users. Low-income earners — those who make less than AU$50,000 — were also likely to go mobile only.
Several drivers are spurring this move to mobile, including improved technology, more affordable mobile services, and telcos upgrading their mobile networks to 4G.
