(Telecompaper) Telstra said it will invest up to AUD 3 billion more into networks and digitisation over the next three years, in a move CEO Andrew Penn said will ensure the company's technological leadership and a significantly improved customer experience. "Our customers and our networks are our biggest assets. We must invest to set new standards and deliver excellent experiences for our customers," Penn said. The CEO will gradually disclose more details about the investment programme over the course of 2017 to 2019 but said a significant proportion of the incremental investment will go towards transforming the next generation of networks.
