The contract is with the department's Technology and Major Capability Group and archTIS said the extension would bring in an additional $250,000 in revenue for FY20.
In a statement, archTIS claimed this validated its expertise in IT engineering, systems integration and security consulting while underlining the strength of the existing relationship.
archTIS chief executive and executive director Daniel Lai said: “archTIS remains firmly committed to exploring all opportunities to further our collaboration with important strategic partners like the Department of Home Affairs in the public sector.
“While our focus on commercialising our SaaS product suite remains our number one priority as we continue to transition towards a product-based business, we welcome the opportunity to further our existing consulting relationship with the Department of Home Affairs through our work with their Technology and Major Capability Group.
"As the company scales down its focus on consulting revenues as the basis for our strategic business growth, the agreement is a significant validation of the quality in industry expertise and experience underpinning the archTIS team and demonstrates our professional consulting services and IT strategic advisory capabilities are still valued.”
