Widespread flooding in northern New South Wales has affected more than 2500 telephone services.
Telstra confirmed today flooding has disrupted power supplies and damaged exchanges, cables and other telecommunications equipment.
An emergency disaster plan to reduce the impact of the floods on telecommunications services is in place but Telstra's mid-north coast area manager, Jim Atkins said the task of restoration is a long way from completion.
Atkins said the plan includes emergency satellite telephones, expanding CDMA and GSM mobile capacity and coordinating the deployment of 276 Telstra staff.
Some staff have put in heroic efforts during the disaster with one technician travelling 15 km down the swollen Clarence River then trekking two km up a mountain to a radio tower to ensure mobile phone services were available.
