About Calleo

Built to serve the Australian Government, Calleo delivers people solutions differently. We don’t provide generic resourcing solutions. Instead, we solve complex workforce challenges in every form, from individual specialists to teams of 100+ professionals.


As an Australian owned SME, we have spent over a decade refining our services to suit the specific needs of Federal Government. As a DISP member, we’re trusted and capable of managing the security clearances of our personnel.


Unlike our major competitors, we deliver significantly better value by investing in our relationships with the technical professionals who deliver critical government programs.

Our Approach

Our people-first culture, national network and proven track record supporting more than 40 Federal Government departments and agencies make us the partner you can trust with your personnel requirements. As a values-led business, we’ve built a strong reputation for our relationship-based approach and our successful delivery has led to ongoing engagements.


Our deep government expertise, genuine care and unwavering commitment to supporting the Commonwealth enables us to scale solutions that meet security and compliance requirements.
