After almost a decade, finally able to see this in my own home:
Speeds are liveable, I'm on least 4.5km of phone cable in the hills here and getting 6.8Mbps down (or about 0.75 Megabytes per second) which is close to the max download speed of ADSL1 (no ADSL2 ports free, I waited 4 months). Video uploads like car cruises I'll be jumping on my phone 4G hotspot though, only got 0.33Mbps upload over ADSL. Phone can smash out 20Mbps upload even with only 2 bars of 4G signal.
The real advantage of ADSL is not speed but quota - 100GB plan to start whereas my phone plan is only 6GB a month!
Wireless NBN will be the next step but the ISP weren't able to get any sort of ETA for my area.
