"We expect the first 120 exchanges to be enabled in March 2006 and 250 by the end of 2006," the company said on a Web site detailing the rollout.
The DSL access multiplexer (DSLAM) equipment the company is rolling out will deliver speeds of up to 24Mbps to customers. So far TPG has only offered speeds up to 1.5Mbps, as it resells Telstra's wholesale ADSL service.
According to the site, significant areas of Sydney, Melbourne, Canberra and Brisbane are due to receive the high-speed access starting in March or April next year, with time frames for Adelaide and Perth being less concrete.
A spokesperson from the company told ZDNet Australia that TPG would soon be issuing a statement on the rollout.
TPG's move is just part of a wave of broadband infrastructure building going on around the nation, with the aim of providing higher speeds and profit margins than those offered by reselling Telstra's current generation of ADSL services.
Most of the larger broadband sellers are involved, including Telstra, Optus, iiNet, Internode, Primus, Adam Internet, and Amcom. Business-grade wholesaler NEC NEXTEP is also known to be slowly upgrading its existing network.
TPG is known to have at least 50,000 broadband customers, and a large number on dial-up.
