I do tend to rant here a bit about aspects of competition policy and regulation. One good move in Oz has been the rules on component pricing - this requires the advertised price to be the total price.
Its most notable purpose was in relation to "cheap flights" which quoted airline prices without the taxes which were then charged separately. Unfortunately its not all that isn't included (think expensive cab fare to out of the way airport).
This comical look could equally be written about telcos.
