When subclass 400 may be relevant
The work to be done, the specialist knowledge required, who will benefit and how the assignment is organised all matter. Calling a trip a meeting or a visit does not decide its legal character.
Bring the scope of work, dates, contractual arrangements and the person’s relevant experience. We consider the activities as a whole rather than choosing a route solely because the stay will be brief.
The assignment and the worker
Specialist assignments can involve equipment, technical systems, commissioning or other knowledge that needs to be explained in context. We help identify the evidence that connects the person’s expertise with the proposed work.
Where a longer-term appointment, recurring role or different activity is involved, another immigration route may need consideration.
Project dates and travel
Travel arrangements and a project deadline should follow a proper assessment. We discuss the issues that need resolution and refer you to current Home Affairs information on eligibility and processing. No outcome or processing date can be guaranteed.
400 visa cost and processing time.
From 1 July 2026, the visa application charge for a subclass 400 is $535 for the main applicant. Home Affairs reports that half of applications are decided within 12 days and 90% within 41 days (updated 2 November 2026). Allow extra time where a project depends on a fixed start date.
