The nation's biggest telco will charge customers $49.95 a month for its slowest and most basic NBN service and at least $22.95 a month to keep their telephone line as part of the deal, even if they don't want it.
The total cost of $72.90 is three times the cheapest wholesale price spruiked by the Federal Government just 14 months ago.
And the NBN offering is even slower than existing $50-a-month plans that run on the pre-NBN technology.
