A very quick google takes me here
and prices appear to be in the "WBC Pricelist - Effective 1 September 2017".
It wasn't very hard to find...
EDIT : Oddly when compared to other packages the pricing of 330/50 is MUCH cheaper on FTTC than on FTTP. There is also no listing for 330/30 on FTTC but there still is on FTTP.
