The presence of non-Telstra DSLAMs allowed the service providers to control the speed of connection, and most offered "uncapped" speeds, allowing the customers to connect at whatever speed their copper pair would allow, up to 8 Mbit/s.
Ratification of ADSL2 and ADSL2 increased the maximum to 12 Mbit/s, then 24 Mbit/s.
Telstra's 2006 introduction of the "Next G" HSPA network (which reportedly covers 99% of the Australian population as of September 2008) with speeds advertised of being up to 14 Mbit/s stimulated investment in wireless broadband by competitors Optus, Vodafone and Hutchison Telecommunications, who are presently expanding their HSPA networks to cover 96–98% of the Australian population.
Delivering competitive telecommunications services to regional and rural areas is a major issue, with Telstra often providing the only telecommunications backhaul transmission infrastructure.
In June 2006, the Australian Department of Communications, Information Technology and the Arts (DCITA) under the then coalition government called for expressions of interest for discussion of how to invest up to $878 million in funding under Broadband Connect program to provide greater access to broadband services in rural and regional areas at prices comparable to services available in metropolitan areas, $500 million of which was envisaged as being available to infrastructure projects.
On 21 September 2006, the government announced they would invest up to $600 million in broadband infrastructure projects in rural, regional and remote Australia under this program.
Prior to IP-based connection to the greater Internet, there existed an IP-based network, linking academic institutions within Australia, known as ACSNet, using the domain and connected to international networks using other technologies.
