MEL-BNE your gunna get 50% more SC's in whatever class. (Like WLG-ACK)
The more I look at this the more it seems the changes to Point earning, Award Flights costs, SC earning etc. seem to overall be neutral (while favoring OZ Domestic WHY class over premium international).
I feel they are more of a smoke screen to mask what they are really doing.
The big change is with Upgrades! 5,000 pts per 450 SC's instead of an UC, what's that worth? $75?
Currently (going N to U), 1 upgrade credit (or 8000pts) used MEL-BNE is worth up to about $700. 2 UC's (or 14000 pts) MEL-AKL is about $1000.

With the changes, you will not be able to upgrade from N at all!

And, with the eligible ecomony classes it will cost 12,000 and 16,000 respectively.
[Spelling: e
comony, a freudian slip i think
