According to this April 2014 site:
https://www.commsday.com/revealed-nbn-co-develops-proposed-product-set-for-fttn-with-diluted-speed-guarantees/

"... while NBN Co provides and installs a network termination device in
the home as part of its FTTH offer, it will not provide a VDSL modem and
voice splitter for FTTN. The onus will instead be on the retailer to
provide and install the modem."

So it would seem to be up to, and dependent on, the retailer/ISP, which
is what Paul Brooks has just said.

And then there's this rather old site, the last posting on the forum
being 201, but even then the advice was not favourable to FTTN:
http://nbnexplained.org/wordpress/technical-points/the-fttn-first-debate/

"FTTN uses more electricity than FTTH, produces more greenhouse gases
than FTTH, features a bigger carbon footprint than FTTH, requires more
maintenance in terms of changing batteries and coolings fans than the
simple splitter boxes used by FTTH hubs, requires larger fridge sized
cabinets on every second street around Australia compared to postbox
size FTTH hubs, yields slower download speeds than FTTH at the same time
as using hardware that stifles competition. An FTTN cabinet is
approximately ~(50x120x150)cm LxWxH. An FTTH Cabinet is approximately
~(47x37x68)cm LxWxH and eight times smaller in volume. Which one would
you like in your street?"

And, in my opinion, if you add wireless, it makes it even worse - more
energy and bigger batteries.
