Tasmania got very lucky with the rollout, we are mostly covered with FTTP, Fixed Wireless and only some FTTN.
We are also lucky enough to have a local business (Launtel) pushing the constraints of the NBN by offering Gigabit at prices that aren't unreasonable ($14.50/day). They are treating it as a new pricing model, why bill the same as ADSL when there are no costs associated with setup and plan changes? They are billing daily which allows more flexibility meaning you could spin up a connection for a day (At an Airbnb for example) or change speed depending on your usage.
Doesn't exactly hit your question but gives a good overview.
