It all depends on location and infrastructure. Most NBN installs are only Fibre to the Node and still use Copper to the house on the existing infrastructure ... if there's issues with the copper back to the Node itself ... there's not going to be much change.

Then there are some providers that are suffering from congestion within their nework anyway to the DSLAMs ... and no matter what service you have ... will be restricted to what is available within the companies core network (risk analysis on the companies behalf and overall busy periods ... they just advise issues due to this and they can't do much ... as they don't want to spend $$$$$ to increase the infrastructure to that area)

One thing I noticed with Telstra in my area (after I managed to get them to provide a port for ADSL when they said there was none ... even though their Wholesale report on the site stated there were ports available in my area) is they advised they could only give me 8Mbps ... and it might only get to 3Mbps most of the time. So if you were an Actual TLS customer you just get the consumer grade crap ports. I went through my work and could actually get a wholesale customer port through their nearest DSLAM. I work for the 'Yes' company LOL.

Was given a 20Mbps port ... and can get that full speed all the time ... susprisingly. Along with my staff discounts as well.

Really ... it's luck of the draw .... my area is only serviced by TLS infrastructure ... so if you go through other ISPs it is Wholesaled out. But I do know TPG customers in the area can get no better than 1Mbps on their ADSL 2 connections. So it's more an issue within TPG's backend network.
