Bank of Queensland has renewed its communications supply contract with Telstra for a further three years in a deal worth $21 million.
Telstra has supplied voice, data and internet services to the bank for the past decade.
The renewal agreement included both fixed and mobile coverage.
Bank of Queensland group executive for IT and operations, Jim Stabback, said Telstra was well positioned "to meet the Bank's evolving business requirements".
But Telstra said its services would enable Bank of Queensland "to increase executive mobility, productivity, accessibility and responsiveness across geographic locations and time zones."
