He recommends building the new fibre to the home network "outside in" fixing the blackspots first and installing where ADSL2+ is already present later
He also recommends retaining the existing copper in parallel to the new system so people have the option to retain the slower ADSL2+ if they want
There is a pdf and video on this page explaining his plan in more detail
At the start there are maps of Sydney and Adelaide showing many blackspots with unacceptably slow speeds
The fibre will be completely independent of Telstra's copper network. It's fair because every carrier will have equal access to the new network.
Of course it’s possible the government will find a way to get it wrong but if they stick with the Hackett plan then I’m in favour
