That test used (IIRC) seven user-channels and three W-NTDs in parallel.

NBN installed four NetComm-developed prototype fixed-wireless network
termination devices (FWNTDs) onto the school's roof for the tests. ...
The Mitchell Park fixed-wireless tower, which also connects a further 11
downstream towers serving more than 3,000 premises in the region, was chosen
for the trial ...
... the tower was selected for 1Gbps testing because its backhaul connects it
to NBN's national test facility in Melbourne via high-speed fibre rather than
microwave, and because it has 11 spectrum bands available to it.
According to NBN corporate public affairs manager Tony Brown, only 20 percent
of NBN's fixed-wireless towers are connected by fibre, meaning the 1Gbps speeds
would only be available for a fraction of fixed-wireless users -- those with
fibre-connected towers, and with 11 carriers available in both the 3.4GHz and
2.3GHz spectrum bands.
NBN being nbn™, we can safely interpret 20 percent as "up to 20%".
