I recently called Telstra to purchase one of their broadband nbn plan. I am currently a Bigpond cable customer and when I checked my monthly usage for the month (to figure out which data quota plan I want to purchase) I was surprised that Telstra moved me to an unlimited plan, even the Sales guy I was talking to was quite surprised as he was not told anything yet.
I then found this news:

Here's hoping by offering unlimited data Telstra won't have the same capacity issue as the other nbn provider :)
I was slightly disappointed with the unlimited offering. I was getting 1TB which was enough for me and I could upgrade to 2TB.
I'm hoping speed doesn't decline.
