400 Temporary Work Visa
The Subclass 400 visa is a temporary visa designed for short-term, highly specialised work, and it is not intended as a pathway to long-term employment or migration.
400 Temp Work Visa Overview
The Australian Subclass 400 Temporary Work (Short Stay Specialist) visa is intended for individuals who need to travel to Australia to undertake short-term, non-ongoing, and highly specialised or skilled work, or who are invited by an Australian organisation to participate in a specific short-term project, cultural activity, or social program.
This visa is generally used to address specialised needs where a suitably qualified local worker cannot be found within a short timeframe. The permitted stay is usually up to three months, and in limited circumstances may be granted for up to six months. The Subclass 400 visa is not a pathway to long-term employment or migration, and strict assessment applies to the nature, duration, and purpose of the proposed activities.
Typical Use Cases for the Subclass 400 Visa
The Subclass 400 Temporary Work visa is not a “general short-term work permit”, but rather a special-purpose visa designed for highly specific circumstances. In practice, the following scenarios are the most common use cases for the Subclass 400 visa:
Short-term, Highly Specialised Technical Work
The most typical application of the Subclass 400 visa is where the applicant possesses highly specialised or scarce skills that cannot be reasonably sourced in Australia within a short timeframe.
Such roles usually involve clear technical thresholds and are not general labour roles or positions that can be easily replaced.
Urgent or Critical Work Assignments
Where a project involves time-critical needs, such as equipment failure, engineering delays, or system outages, Australian organisations may need to bring in overseas specialists at short notice to complete essential work. The Subclass 400 visa is commonly used to address these urgent requirements.
Expert Technical Support, Installation, Commissioning and Training
This may include, but is not limited to:
-
Installation and commissioning of high-end equipment or systems
-
Providing specialised technical training to Australian staff
-
Short-term technical guidance, troubleshooting, or system optimisation
It is important to note that this type of work must be non-ongoing in nature, and is usually directly linked to a specific project or defined task.
Invitation-Based, Non-Ongoing Cultural or Social Activities
The Subclass 400 visa may also be used where an individual is invited by an Australian organisation to participate in short-term, non-commercial, and non-ongoing cultural, artistic, academic, or social activities.
The inviting organisation must have a clear organisational or hosting role in the activity.
Which types of work may appear suitable, but are in fact not appropriate for the Subclass 400 visa?
In practice, the following scenarios are very commonly misunderstood, and are also among the most frequent and most critical reasons for Subclass 400 visa refusals:
-
The work is, in substance, a routine role or part of normal business operations
-
The duration may be short, but the work is ongoing in nature or capable of being repeatedly extended
-
The role does not require scarce skills, and can reasonably be filled by local workers in Australia
-
The role is, in reality, closer to long-term employment, but the Subclass 400 visa is being used as a “bridging solution”
-
The position is described as training or supervision, but in substance involves frontline production or day-to-day operational work
It is important to emphasise that:
The core focus of the Subclass 400 assessment is not “how long the stay is”, but whether the work is, by its nature, a short-term, project-specific, and non-replaceable specialist task.
Eligibility
Assessment of eligibility for the Subclass 400 Temporary Work visa goes well beyond simply “coming to Australia for short-term work”.
In practice, the Department assesses the application across multiple dimensions, including the nature of the work itself,
the applicant’s background, the inviting organisation, and arrangements for accompanying family members.
1. Work and Activity Requirements
The Subclass 400 visa applies very strict criteria to the nature of the work.
The core issue is not how long the stay is, but whether the work aligns with the legal characterisation of
short-term, project-specific, and non-ongoing.
The work must be short-term and non-ongoing, centred on a clearly defined project or a specific phase of work
The role must involve a high level of expertise or specialised skills, rather than a general position or replaceable labour
The role must not displace Australian workers; the inability to reasonably source the required skills locally in the short term
is a key consideration
2. Applicant’s Personal Background
The Subclass 400 visa is not simply approved because a project “needs someone”.
The applicant must be closely aligned with the proposed work.
Demonstrated employment history or project experience directly relevant to the proposed work
Ability to provide objective evidence of professional skills, qualifications, or experience
A genuine and clearly defined intention to undertake only short-term specialist work,
with no indication of long-term work or residence intentions
3. Inviting Organisation / Australian Entity Requirements
The Subclass 400 visa is not a unilateral application.
The role of the Australian organisation is critical to the assessment.
The inviting organisation must genuinely exist and operate lawfully
There must be a direct and clearly defined connection between the organisation and the proposed work or activity
The organisation must have substantive involvement in the project, activity, or work,
rather than acting as a purely nominal sponsor
4. Family Member Arrangements
Where eligibility requirements are met, family members may be included as secondary applicants
in a Subclass 400 visa application.
Family members may be lodged together with the primary applicant
Family members are not permitted to undertake any form of work while in Australia
Their period of stay will generally align with that of the primary applicant,
and they must depart Australia before the visa expires
Allowed vs Prohibited
The Subclass 400 visa has a clearly defined scope. In practice, many problems do not come from “not having a visa”, but from doing something on a Subclass 400 that is not allowed.
Allowed activities
If you stay strictly within your visa conditions, a Subclass 400 holder can usually:
-
Carry out the specific short-term work or activity stated in the visa grant notice, within the approved stay period. The nature of the work, location, and duties should remain consistent with what was approved.
-
In many cases, enter Australia more than once. However, whether multiple entry is allowed, and how long you can stay on each entry, depends on the exact wording in your Visa Grant Notice.
Clearly prohibited activities
The following are high-risk and can amount to a breach. They are also common reasons for refusal, cancellation, or future visa issues in practice:
-
Doing ongoing or repeatable work. Even if each stay is short, if the work is effectively continuous or can be rolled over again and again, it may be treated as outside the Subclass 400 purpose.
-
Filling a standard role in day-to-day operations for an Australian business. Even if the employer is “short-staffed”, that is not what the Subclass 400 is designed for.
-
Carrying out activities beyond what was applied for or approved, such as switching projects, expanding duties, or moving into a different type of technical support.
-
Using Subclass 400 applications repeatedly to effectively live or work in Australia on a long-term basis. This pattern is commonly seen as an attempt to bypass the normal work visa framework.
One key point to remember: Compliance is not assessed by “how long you stayed”, but by what you actually did, and whether it still fits a genuine short-term specialist purpose.
Period of Stay & Visa Features
The Temporary Work (Short Stay Specialist) (Subclass 400) visa is not designed to offer “flexibility of stay”. Instead, it is assessed and approved around specific tasks, a defined timeframe, and controllable risk. As a result, its period of stay and visa conditions are clear, limited, and strictly applied.
Typical Period of Stay
In the vast majority of cases, the approved stay period for a Subclass 400 visa is:
-
Up to 3 months
This is the most common approval period and applies to clearly defined, short-term, one-off specialist work or specific activities. -
Up to 6 months in limited circumstances
This is only possible where the work is genuinely complex, highly specialised, and where a clear justification is provided as to why a longer timeframe is required.
It is important to note that the stay period is assessed and granted upfront at the time of application, not extended later as a matter of course.
Multiple Entry Permission
In some cases, a Subclass 400 visa may be granted with multiple entry privileges, but this is not the default position.
Whether multiple entry is granted usually depends on:
-
Whether the work or activity genuinely requires repeated travel
-
Whether the necessity of each entry can be clearly explained
-
Whether there is a risk the arrangement could be viewed as ongoing work or repeated visa use
The final determination must always be based on the specific conditions stated in the Visa Grant Notice, and should never be assumed.
Common Visa Conditions
Subclass 400 visas are typically granted with binding conditions, including but not limited to:
-
Permission to undertake only the specific work or activity approved in the application
-
A prohibition on any work outside the approved scope
-
A prohibition on long-term or ongoing employment
-
Possible restrictions to a specific employer, project, or activity
These conditions are strictly enforced in practice. Even if the stay period has not been exceeded, conduct outside the approved scope may still constitute a breach and can lead to visa cancellation.
Key Takeaway
The period of stay and features of the Subclass 400 visa ultimately serve one core principle:
It exists solely for short-term, specific, and non-substitutable work, not as a mechanism for flexible labour arrangements or long-term planning.
Whether the Subclass 400 visa is appropriate is not about “how long you can stay”, but whether the work itself genuinely fits this legal purpose.
Common Reasons for Refusal
In practical assessments of the Subclass 400 Temporary Work visa, refusals are rarely due to “incomplete documents”. More often, they occur because the case officer considers that the nature of the work does not align with the intended purpose of the 400 visa. The following are the most common—and highest-risk—reasons for refusal:
The work does not meet the “short-term or highly specialised” requirement
If the case officer considers that the work is merely “short in duration” but does not involve genuinely high-level expertise, or is closer to general technical or skilled labour, it is likely to be assessed as outside the scope of the 400 visa.
The 400 visa emphasises skill scarcity and non-substitutability, not simply a short stay.
The work is considered achievable by the Australian labour market
If the case officer believes the work can reasonably be performed by local workers, or that there is no genuine need to engage an overseas specialist, the application faces a high risk of refusal.
Even if the Australian organisation prefers to use an overseas worker, this alone does not justify a 400 visa.
Unclear boundary between work and visitor or business activities
In practice, many refusals arise where the proposed activities fall into a grey area between “business visits”, “training”, “meeting participation”, and actual work.
If the case officer concludes that the applicant is in substance undertaking work but attempting to characterise it as another type of activity, an adverse decision is likely.
Previous visa history or migration risk concerns
Even if the current work appears reasonable, heightened scrutiny may apply where the applicant has:
-
a history of multiple long stays in Australia
-
frequent use of temporary visas to enter and remain
-
previous refusals, cancellations, or compliance breaches
In this context, the 400 visa may be viewed as a de facto extension of stay or transitional arrangement, increasing the likelihood of refusal.
Insufficient credibility of the inviting party or project
The authenticity of the inviting organisation and the credibility of the project are critical to the 400 visa assessment.
Refusal risk increases significantly where:
-
the inviting organisation’s background is unclear or it has been established only recently
-
the project description is vague and lacks concrete work arrangements
-
there is weak alignment between the invitation and the applicant’s professional background
A key practical reminder is that refusals under the 400 visa are typically the result of an overall risk assessment, rather than a single unmet criterion.
Accordingly, obtaining a professional assessment of the work nature, project structure, and personal background before lodging the application is often far more critical than attempting remediation after a refusal.
400 Visa VS Other Visas
The Subclass 400 is a short-term, specialist work visa, with the core focus on whether the work is short-term, non-ongoing, and not reasonably replaceable.
The Subclass 600 does not permit work, the Subclass 408 is oriented toward specific activities or projects, and the Subclass 482 is designed for formal employment positions. Choosing the wrong visa type most commonly results in a refusal or an adverse immigration record.

Your Next Move
Under the Subclass 400 Temporary Work Visa framework, any arrangement involving coming to Australia for “work” purposes should be professionally assessed in advance. In practice, the real risk is often not that the applicant “does not meet the criteria”, but that the nature of the visa and the nature of the work are misjudged.
If an application is lodged without first clarifying whether the proposed work falls within the legal boundaries of the Subclass 400 visa, the most common outcome is not merely processing delays, but the creation of an adverse immigration record that can directly affect all future work visa applications and even long-term visa pathways.
In other words, any plan to undertake temporary work in Australia should be assessed beforehand. The risks are significantly higher—and it is particularly unsuitable to “apply first and see what happens”—in the following situations:
-
The proposed work sits in a grey area between “technical support” and a “regular role”, with a real risk of being assessed as ongoing employment
-
The intended stay approaches the 3–6 month upper limit, requiring precise legal analysis of what constitutes “short-term and non-ongoing” work
-
The applicant has previous visa refusals, cancellations, or a complex immigration history that cannot be assessed using a standard template
-
The Australian organisation is inviting overseas personnel for the first time and is unfamiliar with Subclass 400 compliance requirements and assessment logic
-
The project or task is highly time-sensitive and cannot tolerate trial-and-error, requests for further information, or the consequences of a refusal
Frequently Asked Questions
Is the Subclass 400 visa a “catch-all” visa for any short-term work?
No — and this is one of the most dangerous misunderstandings. The Subclass 400 visa is only suitable for work that is short-term, non-ongoing, and highly specialised or genuinely non-substitutable. If the work is assessed as a regular role, ongoing in nature, or reasonably able to be performed by the local workforce, the refusal risk is extremely high.
If the work is only two or three months, why is it still refused?
Because the core test for the Subclass 400 visa is not “short duration”, but the nature of the work itself. Even work lasting only a few weeks may fail if it is essentially part of normal operations, repetitive tasks, or filling a staffing gap.
Is it acceptable to do hands-on work under the label of “training” or “technical guidance”?
This is highly sensitive and carries significant risk. If, in practice, the applicant participates in frontline production, installation, operations, or delivers outcomes, it is very likely to be assessed as disguised employment, which is a common refusal ground for Subclass 400 visas.
If an Australian company is willing to issue an invitation letter, is that enough?
Far from it. The Department will assess the genuineness of the inviting entity, the project background, why overseas expertise is necessary, and whether there is any attempt to bypass standard employment frameworks. An invitation letter can support context, but it cannot replace compliance assessment.
Can the same expert apply for the Subclass 400 visa repeatedly?
In theory, yes — but in practice, the risk escalates quickly. Repeated use of the Subclass 400 visa is often interpreted as evidence of de facto ongoing work or residence intentions. Subsequent applications are typically subject to heightened scrutiny or outright refusal.
Can the Subclass 400 visa be used as a stepping stone to another visa after arrival?
This is a very dangerous approach. The Subclass 400 visa is not designed as a transitional visa. Any indication — in documentation or conduct — of an intention to switch visas may lead to refusal and negatively affect future visa records.
If the project is delayed, can the Subclass 400 visa be extended onshore?
Generally not recommended, and rarely straightforward. A project delay does not automatically justify further use of the Subclass 400 visa. Once the work begins to show ongoing or long-term characteristics, extension risks increase sharply.
Can I “help out a bit” with other related tasks during the Subclass 400 stay?
No. The Subclass 400 visa strictly limits activities to the specific work or activities approved. Any additional or incidental work outside the approved scope may constitute a breach of visa conditions.
Why are some highly skilled experts still refused a Subclass 400 visa?
Because being highly skilled does not automatically align with visa logic. If it cannot be shown that the skill is not reasonably available in Australia in the short term, or if the role could be addressed through a Subclass 482 or other work visa, the Subclass 400 is often refused.
What is the most commonly overlooked — yet most critical — risk with the Subclass 400 visa?
Treating it as a “simplified work visa”. The Subclass 400 is an exception mechanism, not a standard employment pathway. Misusing it may result not only in refusal, but also long-term consequences for future work and permanent visa planning.
Is the Subclass 400 visa a “catch-all” visa for any short-term work?
No — and this is one of the most dangerous misunderstandings. The Subclass 400 visa is only suitable for work that is short-term, non-ongoing, and highly specialised or genuinely non-substitutable.
