Firstly not an NBN guru.
Secondly they may not be able to discuss the matter in today's highly
charged pre=election political atmosphere.

You are correct in that the FTTN was upgraded by the labor party to
FTTH.

However right now, Labor needs to balance the books somehow for the May
budget.
If it doesn't the disappointed public may force an election a lot
quicker than expected.

So... If we are getting FTTN, or the Kerb.. And that saves 

8,200,000 HH's * $350 Kerb to House and $150 (CPE) then the total
savings to the NBN would be 4.1 billion and by carrying forward the
offset in capex as a current account surplus, the budget is almost
balanced.

Now the only problem is how to power the device at the Kerb splice to
run to the home or the radio device.  (Sorry Labor, I can't solve all
your probs with a single email.)
 
But we keep getting the rest of the NBN. That is a good thing.
