The number of residential NBN services has declined for the first time, according to figures showing connections between NBN Co and retailers.
Services in operation fell by 9000, or 0.1 per cent, to 8.73 million in the December 2022 quarter, the ACCC's NBN Wholesale Market Indicators Report said on Friday.
"About 20 million Australians use the NBN network each day which means there is a smaller pool of potential new users of the network," an NBN spokesman said.
"Combine that with the completion of the build (and) you see more modest new connections."
The top three providers - Telstra, TPG and Optus - lost a total of 95,000 services to shave their market share to 77.9 per cent.
But Vocus and other smaller providers gained about 86,000 services, to 1.9 million. They now have 22.1 per cent of the market, up from 14.6 per cent two years earlier.
About half of all services are for 50 megabit per second while 20 per cent, or 1.8 million homes, are getting 100Mbps or more.
The ACCC report does not show connections between retail service providers and the end user.
The latest weekly summary of the NBN rollout showed 8.55 million premises had active services installed, up 40,000 since June 30, 2022.
About 12.23 million premises are ready to connect, up 100,000 since June 30.
