Not all temporary work visas in Australia are created equal. Confusing the 403 and 400 visas could seriously derail your plans. If you’re aiming to work temporarily in Australia, understanding the unique purpose behind each visa is crucial to avoid costly mistakes. So, what is the key difference between 403 and 400 Temporary Work Visas?
The Subclass 403 visa is tailored for official government, diplomatic or international organisation roles. The Subclass 400 visa, on the other hand, is designed for short-term, highly specialised work that local workers can’t easily do.

The Difference Between 403 And 400 Temporary Work Visas – A Quick Answer
The difference between 403 and 400 temporary work visas is clear once you focus on purpose, eligibility and duration.
The 403 visa is designed for diplomatic staff, foreign officials and those involved in international cooperation programs. On the other hand, the 400 visa helps skilled professionals enter Australia for short-term technical tasks or urgent projects that require expertise not found locally.
The 403 visa often covers longer assignments linked to government duties, while the 400 visa fits quick, high-impact jobs that last up to three months. Both require approval, but their goals and conditions vary greatly.

What Is a 403 Temporary Work Visa?
The Subclass 403 Temporary Work Visa supports individuals coming to Australia for international relations or diplomatic roles. It is not designed for general employment but serves a niche purpose. This visa helps specific foreign nationals who enter under special programs or bilateral agreements.
Subclass 403 includes multiple streams, but most applicants enter through the International Relations stream. This visa type shows Australia’s commitment to supporting diplomatic presence, cultural exchange and certain agreements between countries.
Purpose (International Relations Stream)
The International Relations stream under Subclass 403 supports foreign government representatives, domestic workers of diplomats and individuals involved in special international programs. It does not serve the same function as a general employment visa.
It allows temporary entry for those who support foreign government activities, maintain bilateral cooperation or participate in privileged projects tied to foreign relations. The visa ensures Australia meets its obligations under international law and established agreements.
Common Use Cases
The Subclass 403 visa supports roles that are part of official, diplomatic or international obligations. These cases reflect Australia’s commitment to global cooperation and formal agreements.
- Foreign diplomats and consular staff
- Domestic staff of diplomats
- Participants in international cooperation programs
- People covered under bilateral agreements or privileges
These roles are tied directly to official duties. They do not involve general labour or commercial activity. Every use case must align with Australia’s foreign relations and diplomatic priorities.
Duration and Conditions
The 403 visa usually allows stay periods matching the assignment or diplomatic role, often up to 2 years or as determined by the agreement. Extensions may be possible through reapplication or depending on the diplomatic mission’s needs.
Holders must meet specific health and character requirements. They cannot work outside their approved scope, and any change in assignment or status must be reported.
What Is a 400 Temporary Work Visa?
The Subclass 400 Temporary Work Visa is for highly skilled professionals invited to take part in short-term, specialised work in Australia. It does not require long-term residency or ongoing employment and is ideal for urgent or expert-level tasks.
This visa supports those who bring unique knowledge or technical input not readily available in the Australian workforce. It also applies to foreign workers addressing critical shortages or emergencies.
Purpose (Short-Term, Highly Specialised Work)
This visa targets short-term roles with high impact. It is not for routine jobs or long-term hires. Applicants usually hold niche expertise or handle time-sensitive work that supports Australia’s short-term labour needs.
These professionals contribute to projects, training or consultancy where no Australian worker can fill the gap. The visa reflects the value of quick knowledge transfer and timely project delivery.
Common Use Cases
The Subclass 400 visa focuses on short-term roles that require specific skills not available within Australia. These roles often address urgent needs, specialised tasks or technical challenges.
- Engineers supporting project installations
- Specialists performing equipment repairs
- Consultants providing expert advice
- Workers handling emergency or crisis support
Every case must prove the necessity of the applicant’s presence. The sponsoring party must show that the skill set is not available locally.
Duration and Conditions
The 400 visa typically grants a stay of up to 3 months, which can be extended 6 months in exceptional cases. Applicants must show that the work is non-ongoing and cannot be sourced within Australia.
Visa holders must comply with activity restrictions. Any changes in job scope, employer or timing may impact the visa’s validity.
Key Differences Between 403 and 400 Visas
Both visas are temporary, but differ in purpose, eligibility and conditions. Choosing the right one depends on your role, who you represent and the nature of your work in Australia. Here’s an overview to help you out:
Purpose:
- 403 Visa: For official government, diplomatic or international organisation roles. It supports Australia’s foreign relations and allows entry for official duties, not business or general work.
- 400 Visa: For short-term, specialised work where local skills are unavailable. Ideal for urgent projects, technical tasks or expert advice on a temporary basis.
Who Can Apply:
- 403 Visa: Restricted to diplomats, foreign officials and staff linked to official international programs or agreements. Usually sponsored by foreign governments or recognised bodies.
- 400 Visa: Open to individuals with specialised skills invited by Australian employers for short, high-value tasks that can’t be filled locally.
Length of Stay:
- 403 Visa: Generally aligned with diplomatic assignments, often up to 2 years or more, with possible renewals.
- 400 Visa: Short stays of up to 3 months, rarely extended beyond 6 months, suited for quick, critical jobs.
Eligibility:
- 403 Visa: Requires formal ties to a government or international organisation, backed by official sponsors. Focuses on non-commercial, diplomatic work.
- 400 Visa: Requires proof of unique skills and employer sponsorship, with clear evidence the job can’t be done locally. Must be temporary and well-defined.
Work Rights:
- 403 Visa: Work strictly limited to official diplomatic or government functions; no other employment allowed.
- 400 Visa: Work is restricted to the nominated job only, with no changes or extensions without a new application.
How to Choose the Right Visa
Selecting the correct visa is not about personal preference. It is about matching the visa to your situation and purpose. Misapplying can lead to delays or rejections.
If you’re unsure, focus on your role’s intent. Is it tied to official government functions? Then 403 is likely the fit. Is your visit for a specific, skilled project? Then 400 is your route.
Example 1: Technician for a 6-Week Repair Job
An engineering firm needs a technician to repair custom machinery. The firm confirms that no local worker has the skill. The 400 visa fits here. It is fast, focused and designed for tasks like this.
Example 2: Foreign Diplomat’s Assistant
A diplomat from another country brings a domestic assistant. This is a role under the diplomatic service, not general employment. The 403 visa applies here, as it supports such official attachments.
Getting expert help ensures compliance. A migration agent can guide you to the right visa, help you collect the needed documents and avoid rework or refusals.
Understanding the Application Process
Knowing how to apply can ease stress and help you stay on track. Both the 403 and 400 visas involve formal steps, required documents and time-sensitive details. While their documentation differs, the overall process is quite similar:
- Confirm your visa stream and eligibility.
- Gather documents: passport, employment letter, sponsorship forms.
- Apply online through the official immigration portal.
- Pay the visa fee.
- Wait for approval or further instructions.
Required Documents
403 Visa:
- Letter from a foreign government or sponsoring agency
- Proof of diplomatic role
- Passport and ID
400 Visa:
- Job offer or contract
- Evidence of specialised skill
- Employer statement explaining the need
Missing documents delay approval. Always double-check requirements.
Processing Times
- 403 Visa: Usually 4–6 weeks, depending on government coordination
- 400 Visa: Often 2–4 weeks, especially when urgency is shown
Urgent cases may receive priority, especially under the 400 stream.
Common Pitfalls That Can Cause Visa Delays
Applying for a 403 or 400 visa involves strict requirements. Small errors or missing details can lead to setbacks, so it’s important to watch out for common mistakes, including:
- Wrong visa stream selected
- Missing or unclear job purpose
- Insufficient evidence of skills
- Invalid sponsorship or employer documentation
By carefully following the official steps and preparing your documents properly, you can reduce the risk of delays. If needed, consult a migration expert for guidance.
Final Thoughts
Being aware of the true difference between 403 and 400 temporary work visas can save time and prevent serious mistakes. The 403 visa connects directly to official, diplomatic and international roles. It suits those backed by foreign governments or recognised programs.
The 400 visa, on the other hand, targets highly skilled professionals needed for short and urgent tasks in Australia. It’s ideal for companies facing technical problems that require overseas support.
The key is not to guess but to align the visa with the nature of the job. When you’re clear about your purpose, the application becomes smoother and faster. If there’s any doubt, reach out to a migration expert to ensure you take the right step forward with confidence.
