I was thinking about these rates last night.
If you look at what current legislation say about the rates, they may only increase it yearly and not more than inflation and CPI.
Now we all know that the current discounted rates will not make them a profit, they can not even get to break even point on those rates.
So how do they expect to make money ?
Clever they are..........................................................
I reckon the alternate rate is the actual rate (the figure is close to what they need to break even and make a profit)
So the increases will be based on the alternate rate - thus it will be as per legislation.
Remember that discounts is not a legal requirement, it is discretionary. Discounts are normally used as an incentive to get people onto a program/get them to start buying your product etc.
So how will they make money ?
All they need to do once enough people is registered, is to give less discount, or take away the discount altogether.
That is the only thing that makes
sense cents

Otherwise what will the use be of a state subsidized system, which is actually suppose to make money ?
So I reckon, once you registered, you are well and truly fucked !
You need to look at the alternate rate and understand, that is where they need to be !!!
The discounts may be a powerful enticement now to rather register, but what are you going to do once discounts fall away ?
They are not obliged to give discounts indefinitely !!!
Gazette says :
The Gazette also states that
adjustments to the tariffs and amounts can still be made.
"The increase will be determined by the minister and will not exceed the Consumer Price Index (CPI) for the preceeding 12 months."
I reckon there is their loophole, although the cannot increase rates exponentially, they can adjust tariifs and amounts.
Play around with discounts etc ?
