South Australia will seek expressions of interest from the private sector for the revamp of government ICT systems.
The state government said market approach documents are being prepared for release "soon" for the program.
The government spends around $260 million on cross-government ICT every year.
A statement issued by the government said that the expression of interest process will increase that amount by $100 million.
In a statement the state's public sector minister, Susan Close, said that the process will "enable innovation while still adhering to the principles of fairness, equity and transparency".
Industry will be invited to offer ideas for the revamp of government ICT systems.
In the past, procurement processes have restricted the ability to invest in innovative solutions, Close said.
"This is all about using government purchasing to help create ICT services in South Australia that drive locally-based innovation and growth in the ICT industry," the minister said.
"It's about driving economic growth through innovative solutions. We expect this Expression of Interest process to deliver positive changes to the public service in the way we work, boost productivity and position South Australia for the future."
"As part of our economic plan for South Australia, we've set a priority of achieving growth through innovation," South Australia's premier, Jay Weatherill, said in a statement.
"In South Australia we have all the ingredients for innovation success: A strong research community, entrepreneurial businesses and creative communities.
"We're seeking innovative proposals from the ICT industry to add value to the services delivered to the community."
