The 400 Short-Stay Specialist Visa is often used for project-based assignments, technical installations, or short-term consultancy roles where niche expertise is required, and local talent is unavailable.
This case study highlights how Interstaff’s strategic expertise helped an employer overcome immigration challenges and meet urgent workforce needs.
The Case:
Urgent 400 Visa for Oil and Gas Specialist
A client in the Oil and Gas industry faced a critical operational challenge—an urgent need for a highly skilled specialist to travel to Australia and perform essential repair and maintenance work on-site.
The nature of the task was time-sensitive, with direct implications for health and safety compliance and the continuity of project milestones. Delays in the specialist’s arrival risked breaching safety protocols, disrupting operations, and significant financial and reputational costs.
To address this, Interstaff was engaged to manage the Subclass 400 Visa process under tight time constraints. Our team worked swiftly to assess eligibility, gather documentation, and lodge the application with precision—ensuring the specialist could arrive in Australia without delay and with the client’s project remaining on track.
