Well almost a month on NBN and so far no complaints. Actually asked a bloke at work who has FTTP and he said he was getting between 40-45mbps~ and at first it confused me but then I remembered my area is only recently NBN ready so will see how it goes when more connect to it.
I just did another speed test and it was 11 ping, 48.2 down / 18.9 up. Then I did a test on my Telstra 4G phone and it was 29 ping, 168.9 down / 37.8 up...Yep we stuffed this up!
No wonder why NBN co are worried about 5G when 4G is getting that
