Two hundred and fifty jobs will be generated in Adelaide as the Turnbull Government modernises the nation's visa and citizenship services.

Services currently provided from Britain, Canada and Sydney will be relocated to Adelaide bringing the Department of Home Affairs client enquiry services into one location.

They will be delivered by Australian company Datacom Connect Pty Ltd under a contract with the Department of Home Affairs.

The Minister for Home Affairs and Minister for Immigration and Border Protection Peter Dutton said that the Department currently handles over 1.5 million enquiries a year.

"Moving enquiry management services to a dedicated external provider is expected to reduce the wait time for clients and improve their access to the information they need in a timely manner," Mr Dutton said. 

"Approximately 250 Datacom employees will be dedicated to delivering services for the Department. They will be based at one service centre in Adelaide, rather than being split around the world creating opportunities for Australian job seekers in Adelaide."

The new arrangement is part of a long-term programme to bolster Australia's immigration services, with a focus on creating a more user-friendly experience for visa and citizenship clients, encouraging a greater uptake of digital services.

Further improvements to immigration services will be rolled out during the course of 2018, including a new user-focussed visa and citizenship website, enhancements to the ImmiAccount online visa application portal and changes enabling clients to reschedule their appointments online.

Datacom will begin delivering client enquiry services in full by mid-2018. Transition arrangements will be carefully managed to ensure minimal impacts to clients.
