Most of the major players in the ISP market have logged ACCC complaints against telstra because their retail price is much lower than their wholesale price.
2 outcomes will likely occur:
1. Telstra will get slammed and have to offer better pricing to all other carriers (WIN WIN)
2. Better deals, companies with their own infrastructure such as Internode, Iinet, Adam etc will be brining out new plans to combat the price squeeze, and you wont get locked into 36 months on a contract as you would with Telstra
