On 3 September 2021 Cellnet Group Limited announced that it had received verbal notification from Optus that it will not be renewing its Master Supply Agreement and Statement of Work Agreement. The company has now received written confirmation from Optus confirming that the Agreement is to be terminated and is scheduled to end on 8 December 2021. This is subject to any request from Optus for a transitional period beyond the scheduled effective date, for which Optus may require a month-on-month extension until completion of the transition from the company to the relevant third-party supplier.
