Imo it's far more likely the problems are caused by the un-named ISPs 
having inadequate contention ratios in the subject areas (or even all 
areas). The News Corp article's credibillity suffers, imo, from the failure 
to mention that even if NBN Co. supplies a perfect service to some area, if 
an ISP retailer in that area skimps on provisioning/contention ratio, then 
their customers will not receive the requested speed, except maybe in off 
peak times of day/night (because e.g. there'll be too much data traffic 
trying to get through a too small "tube" from the ISP's point of 
interconnect with the NBN service). Similar potential problem has long 
existed with ADSL, but seems possibly could be exacerbated with NBN due 
also to NBN Co's CVC fees and some ISPs minimising how much in CVC fees 
they pay. 

A search such as "nbn contention ratios cvc back haul" will turn up a heap 
of info.

Inadequate ISP back haul can certainly be the problem... After I got NBN 
connected a few years ago (FTTP), I decided to trial a different and 
cheaper ISP who were offering a free trail of their 100Mbps service. 
Couldn't get more than about 60 Mbps most times to major AU sites. Long 
story short ISP claimed they had plenty of back haul for my area, but had 
ordered more in expectation of more new customers, told me to check 
numerous things about my router, PC, firewall, etc. Wasted hours checking 
stuff with no improvement. About 2 weeks later "miraculously" speeds were 
suddenly about 96Mbps all the time. Why? Their back haul increase order had 
just been implemented by their upstream telco carrier. 

Decided I'd rather stay with my pre-existing bit-more expensive ISP - where 
I've never before or since had contention ratio issues - rather than risk 
potentially frequent issues with a cheaper ISP.
