Contractors laying the National Broadband Network (NBN) have cut the internet connections to thousands of homes and businesses in Queensland, a local councillor has said.
Ipswich councillor Paul Tully said the workers cut a major cable outside the Goodna telephone exchange.
Telstra said third parties cut the cable, but would not say whether it was NBN contractors.
Telstra spokeswoman Jane De Gault said 2,400 homes and businesses have lost their internet and phone connections, which won't be fully restored until Friday evening.
"Pieces need to be spliced back together; it's very time consuming," De Gault told AAP.
"You need specialist people, specialist equipment, and there's digging, too."
Tully said he had received numerous complaints over the past six months about NBN contractors abusing householders, blocking roads and driveways, and having inadequate traffic controls.
"NBN is a nightmare for local residents," he said in a statement.
"All the goodwill toward NBN's high-speed broadband network is gone."
