FTTNode - this is interesting. your average Australian is 500metres from a Node, and testing shows over 90mbps is realistic on new copper - so close to the best you can get from NBN FTTP that it does not matter. BUT ....
1) If the copper is old/repaired (etc) that you will not get this speed - it is impossible to tell for sure, but if you get 24Mbps from ADSL, then you *should* get 90+ from FTTN NBN - with a likely linear relationship if you get less than 24 on ADSL
2) if you are 600m from the node you will likely only get 50mbps dropping (in an oddly linear way) to 25mbps if you are 1.2km from the node

The theoretical max speed of ADSL2+ is 24mbps and it's not likely many (or anyone) will achieve it.
ADSL2+ speed depend on the users distance from the phone exchange or 'DSLAM' (essentially a mini exchange for simplicity sake). Most ISP's place their equipment in the phone exchanges and i'm pretty sure Telstra is the only ISP to have DSLAM's dotted around suburbs.
Unless your virtually right next door to an exchange or DSLAM, your won't get 24 mbps.
FTTN is essentially like lots of mini exchanges (nodes) dotted around suburbs, typically you'll find a light green cabinet located next to those phone line distribution poles, I believe the phone tech comes out and taps your copper wire in that pole to the NBN cabinet.
Given this, the speed you get from NBN has no baring on what you got from ADSL.
FTTC is fibre from that NBN cabinet, up the street to a pit, then copper from that pit to your house for the last 'hop'.
FTTP is of course replacing that last hop of copper with fibre.
I see FTTN as a much faster/cheaper way to get higher speeds to homes with the ability to progressively move to the ultimate FTTP as smart in Australia given our sp****ness.
The problems you see are down to the RSP's (retail service providers) not purchasing enough CVC from NBN to service an area typically. That's largely been sorted now.
I switched from 14mbps ADSL2+ (on a DSLAM) to NBN 50/20 and never had a problem, getting 44/18 typically from memory, can stream 4K shows on Netflix etc whilst streaming 1K shows on 2 other TV's without issue, no chance of doing that on ADSL2+.
