Digital services corporation Atos Australia has won a five-year, $124.3 million contract with WA's Health Support Services to provide data centre and cloud services that host clinical and non-clinical applications for WA Health, taking over from incumbent Fujitsu.

The deal is the first tranche in the $408m HealthNext project, WA Health's part of the $3 billion GovNext-ICT program that will see new infrastructure rolled out to support the WA public sector.

Atos is one of three suppliers on the GovNext-ICT panel; the other two are Datacom and NEC.
