Purpose of This Call
RSB now invites eligible organisations and individuals to indicate their interest. Throughout this document, "Consultant" refers to both organisations and individuals. RSB is building a pre-approved External Consultant Roster: a qualified pool of selected specialists and organisations that will be called upon for project-based work over the next 2 years.





Consultants accepted onto the roster will complete a brief onboarding process to become familiar with RSB's systems, ways of delivering services, and sustainability framework. When a specific project or capacity gap emerges, RSB will contact roster members whose profile best matches the assignment, share a defined scope of work, and invite them to submit a proposal.

Inclusion on the roster is an expression of readiness and fit and not a guarantee of immediate work or remuneration.
