TELSTRA claims just five per cent of south-west landline phones and 18 per cent of internet services remain offline after the latest restoration efforts.
A Telstra media spokesman said technicians had made solid progress on connecting the services overnight, in addition to the mobile services and large business customers previously restored.
"This means that there are now approximately 3000 fixed line services and a similar number of internet services remaining to be connected and technicians will be connecting them one by one as cabling and equipment installation work continues," he said.
"Telstra is upgrading our Next G wireless network infrastructure at Warrnambool Exchange to provide an additional 60 per cent of capacity which will provide our wireless customers in central Warrnambool with a noticeably better Next G data experience."
Tonight representatives from Telstra will take part in the Warrnambool Business Community Forum, hosted by the Warrnambool City Council at the Lighthouse Theatre from 7.30pm.
Community forums are also confirmed to be held in other towns including Hamilton, Portland, Edenhope, Heywood, Casterton, Balmoral, Coleraine and Penshurst from Tuesday of next week.
