Starting in October, Telstra will offer NBN Co services to the project's trial sites in Tasmania. The move indicates that the telecommunications company aims to move into the NBN environment.

David Thodey, Telstra's chief executive, said that the company would offer the new services and products to one hundred existing customers from October to the end of the year. The company wants to test the compatibility of NBN infrastructure to its own service with the trials.

"The pilot, commencing in October, is an opportunity for Telstra to assess how BigPond broadband services and next-generation digital home products such as T-Hub and T-Box perform over the NBN," Thodey said.

"It's the first time that Telstra has sought to access another fixed network rather than use our own, so it's important we ensure our products and services work smoothly."

T-Hubs and T-Boxes will be provided to some of the customers for free during the trial period. Meanwhile, the service of some existing BigPond customers will be upgraded to super fast broadband speeds for a few months.

Currently, iiNet, Internode and Primus have already offered retail services in test sites. The customers would be residents of Midway Point, Scottsdale and Smithton.

"The whole reason for the trial is an indication that we are planning to (re-sell NBN Co services). We just want to make sure that everything is working correctly before we could make a commercial offer to our customers," said Jon Court, Telstra's spokesman.
