Resources company BlueScope Steel has renewed its outsourced IT services agreement with CSC for another four years.
The contract covers "consulting, applications development and support, disaster recovery, systems integration and end user services on a variety of technology platforms".
Once the four-year period is over, a further two lots of two-year extensions are also possible.
The contract has run since May 2000. Its renewal comes during a downturn in the steel industry.
"We have been pleased with our relationship with CSC through the term of the last contract. They continue to support us well in a difficult business environment," said the company's CIO Andrew Baker.
"The further cost saving initiatives and service delivery improvements we plan to deliver with CSC are important to us."
