In an email sent to users, Telecube said: "The purpose of this letter is to inform you that Telecube will no longer be offering NBN services from 4th September 2018, after that date the NBN services are in danger of being disconnected.
"Please act promptly and arrange for a new provider as soon as possible."
The chief executive of Tasmania-based ISP Launtel, Damian Ivereigh, had warned a few days ago that smaller RSPs who were selling NBN connections could be forced out of business from October onwards.
Telecube's liquidation notice said a general meeting of company members had been held on 29 August and resolved to wind up the company and appoint Matthew Jess of Worrells Solvency & Forensic Accountants as liquidator.
Ivereigh noted that several ISPs were offering discounts to try and attract Telecube's customers.
"Unfortunately this is the typical knee-jerk answer to 'how can we get customers?', which created Telecube’s problems in the first place," he commented.
"Our industry has to get out the habit of discounting to get customers, we need to build value in other ways – like customer service!"
