Currently I pay AUD$79 per month for the privilege of 1.4mbp/s down and 100kp/s up. My area is slated for the NBN, albiet HFC (using old coaxial) to commence building in 2019. Bloody bonza, mate.
I'd take HFC over FTTN. Last time I lived with DSL I enjoyed the same kind of speeds you're getting and three visits from Telstra minions came out to "sorry, nothing we can do". I'm in no hurry to play that phone-line lottery again.
I feel your pain as I pay about the same for 1.1mbps down. I can't get any faster speeds (I checked when I worked for Internode) and speed drops whenever it rains.
I once tried to follow the Udacity course on Tensorflow, but could not download a 10GB that was needed for one of the exercises. Download kept failing and restarting and eventually I killed it after 8 days. Utterly shameful.
