As reported in February, NBN Co had to stop accepting orders for new HFC services due to a shortage of cable modems.
Modems still in stock were used to connect premises occupied by medically vulnerable customers, and more than 230 such customers were connected since 2 February 2021.
NBN Co says it will continue to offer priority service to vulnerable customers.
HFC services were also provided to customers who have moved into premises that had been disconnected from the network, as well as those living in or working at premises where the disconnection date had passed and where no legacy service was available.
More than 47,000 premises have been connected to the HFC network since 2 February 2021.
A further 31,000 connections are being made to premises without a legacy phone or internet service and premises occupied by medically vulnerable customers.
The plan is to complete as many of these connections before to taking new orders on 24 May 2021.
RSPs will be provided with details of NBN Co's plan on 8 April 2021, but it will be contingent on continued deliveries of modems. This means it is possible that not all prospective customers in areas served by HFC will be able to order services immediately.
"We are confident that we will receive regular deliveries of new HFC modems in the weeks and months ahead to enable the resumption of new HFC connections from 24 May 2021," said NBN Co chief customer officer Brad Whitcomb.
"We appreciate customers' patience during this global chipset shortage that has temporarily delayed some new HFC connections to the NBN network."
