Telstra will spend a further $200 million on improving its network following a string of outages that have damaged the telco giant's reputation.
The investment comes on top of $50 million Telstra pledged in May.
Australia's biggest telco recently completed a thorough review of its core network and IT systems, pinpointing sources of "potential risk", chief executive Andrew Penn said in a blog on the company's website.
The money will come from Telstra's existing capital program over the next six to 12 months, and will provide a higher degree of network resilience and improved performance, Mr Penn said.
The company aims to enhance its mobile network's resilience, improve recovery times and create more effective real time monitoring.
Telstra will also work to improve reliability and resilience in its core network, and boost ADSL broadband capacity to meet increasing customer demand, Mr Penn said.
"These are important measures and I want to assure you that I am committed to doing everything we can to strengthen our network for you," he said.
Telstra boasts it has the best telco network in Australia, and charges customers a premium for its services.
Mr Penn said all network operators around the globe face the risk of disruptions, whether it be bad weather, accidental damage, or hardware issues.
"What I am committed to though is continuing to invest in building the durability and capability of our network, and in our ability to respond quickly if things do go wrong to minimise the impact on customers," he said.
Telstra shares gained seven cents, or 1.3 per cent, to $5.48.
