The Australian opposition have released "Fast. Affordable. Sooner. The Coalition’s Plan for a better NBN". This proposes halting the roll-out of the NBN Fibre to the Home in Australia and using Fibre to the Node instead. We have had TFFN in Canberra for just over a decade, with the Transact system. If you have power poles handy, and the citizens don't mind more overhead wires, it is a cost effective system. Also it works okay in new buildings. My apartment building has a fibre optic node in the basement and twisted pair copper to each unit. But if you are going to the trouble of putting new cables underground, then they might as well be fiber-optic, as most of the cost is in digging the trenches.
If the government, whoever they are, want to save money, they could
prioritize fibre roll-out in greenfield sites and areas with no, or poor
broadband. The areas with copper phone and Pay TV cable could be left
for last, where it is working okay. This would be a slight change to the current government's NBN FTTH to achieve cost savings proposed by the opposition.
