We have had NBN for 6 or 7 months now and it's great. It was a total nightmare getting it connected in the beginning but we got there eventually. I can only comment on Telstras service personally and on FTTN (Fibre To The Node) where the nbn is concerned however my sister has been through 4 providers now trying to get hers sorted. The speed you will get not only depends on the speed you pay for but also how far you are from the node and pillar in the street, the further you are the slower the speed, my sister who lives in the Corromandel Valley area is over a kilometre from their node so didn't expect much but when they first got connected it was great, however as time went on it got slower and slower, she complained and complained and was instructed to run test after test by first Adam then iiNet and internode but they refused to send a tech out and when they eventually did they stated it was her distance that was the problem, she then contacted my republic a new company who promise the fastest speed possible, same issue initially but they did send a tech and this time the tech really knew his stuff and actually wanted to help, she was told the original tech connected them up wrong in the first place, so now she has 10mbit down and 6mbit up on a stable connection. At its worst previously it wasn't usable at all. So it's basically a lottery depending on where you live, who you talk to on the phone and who you get as a tech. Don't ever let them tell you that's the best we can do if you're not satisfied, minimum speeds should be what my sister is getting. We are in Park Holme and less than 200m from the node and pillar our attainable speed is over 100mbit down and over 50mbit up. If you are getting FTTP (Fibre To The Premises) then your connection will be a direct fibre connection and non of the above is relevant.
