TL;DR: The Subclass 400 (Temporary Work, Highly Specialised Work) visa lets Australian employers bring an overseas specialist here for up to six months without needing formal sponsorship accreditation. It is fast, affordable, and well-suited to urgent, project-based needs, but it only delivers when you match it to a genuinely temporary, highly specialised gap and build the evidence to prove it.
-
Grants stays of up to three months (extendable to six months with demonstrated business need).
-
Does not require you to become an approved sponsor, unlike the Subclass 482 visas.
-
Base application fee is AUD 535, significantly lower than longer employer-sponsored pathways.
-
Well-prepared applications are typically processed within two weeks.
-
Applications with complete, well-structured evidence are approved at around 90 percent, incomplete ones are not.
You have an urgent problem. A piece of complex machinery has arrived from an overseas vendor and nobody in the country can commission it, or a critical system has failed and the one engineer who understands it lives on the other side of the world. You need that person here in weeks, not months, and you have started to hear about a visa that promises exactly that kind of speed.
That visa is the Subclass 400, the Temporary Work (Highly Specialised Work) visa, and it is one of the most useful instruments available to an Australian employer facing a short, sharp specialist need. It is also one of the most misunderstood, which is where a lot of well-intentioned applications quietly come undone.
I want to walk you through how this visa actually works in practice, where it genuinely helps you, and where it is the wrong tool for the job.
What Is the Subclass 400 Visa?
The Subclass 400 visa is a short-stay visa built for genuinely temporary, highly specialised work. It exists to let you bring an overseas specialist into the country for a defined task that requires expertise not readily available in the local labour market.
The visa is usually granted for a period of three months, and in some cases it can extend to six months where you can demonstrate a strong business need. It cannot be extended beyond that, which means that if the work runs longer, you are looking at a new application rather than a renewal, and it does not open a path to permanent residence.
That last point is worth sitting with. The Subclass 400 visa is a targeted, time-sensitive instrument for a specific gap. Treating it as a quiet workforce strategy is where employers tend to run into trouble with the Department of Home Affairs.
Key Point: The Subclass 400 is a short-stay visa for genuinely temporary, highly specialised work, not a recurring workforce solution or a pathway to permanent residence.
Why Do Employers Reach for the Subclass 400 visa?
The appeal is real, and it comes down to a few practical advantages that matter when the clock is running.
Speed relative to sponsored pathways
Most well-prepared applications move quickly. Complete and clearly documented cases are often processed within two weeks, and a clean, well-evidenced application tends to move faster than a thin one. Compared with the multi-stage sponsorship process attached to a longer-term visa, that is a meaningful difference when your project has a fixed start date.
No requirement to become an approved sponsor
The Subclass 400 visa does not require you to hold formal sponsorship approval in the way the longer pathways do. Your organisation still plays a genuine role, because you must provide detailed support explaining the work, the specialist requirement, and the engagement arrangements, yet you avoid the sponsorship accreditation burden entirely. For a business that needs one specialist for one task, that removes a great deal of friction.
Cost that reflects the shorter commitment
The base visa application charge sits at AUD 535 for the primary applicant, which is a fraction of what the longer employer-sponsored route costs once you factor in nomination fees and the Skilling Australians Fund levy. When the need is short and defined, you are not paying for infrastructure you will never use.
Flexibility for project-based and niche needs
This visa suits the specific and the unusual. Manufacturing companies, engineering firms, and infrastructure operators regularly use it to bring in overseas technicians to install proprietary systems, and it works well when critical equipment fails and you need the one person who can diagnose the fault quickly. If your need is narrow, urgent, and genuinely temporary, the shape of the visa fits the shape of the problem.
Key Point: The Subclass 400 visa offers speed, low cost, and no sponsorship accreditation requirement, making it a genuinely strong instrument when the need is short, urgent, and clearly specialised.
Who Does the Subclass 400 Visa Genuinely Suit?
The Subclass 400 visa works best for employers with an urgent, time-limited need for expertise that the local market cannot supply. Think of a specialist commissioning a bespoke installation, a consultant engaged for a short and clearly defined project, or a technical expert whose particular knowledge is genuinely scarce.
The key word throughout is specialist. Specialist work requires a high level of specific expertise, technical knowledge, or skill that is not generally available here for the purpose required. The real question is not simply whether your candidate is competent in their field, which many people are, but whether the particular skills they bring are genuinely scarce or uniquely suited to your specific task.
If the role you are trying to fill resembles a standard job, this is not the visa for it, and the Department will treat it accordingly.
Key Point: Eligibility hinges on genuine scarcity, the question is not whether your candidate is skilled, but whether their specific expertise is unavailable in the local market for your specific task.
What Are the Honest Caveats?
Here is where I earn my keep, because the parts people skip over are the parts that decide the outcome.
The Subclass 400 visa is a short, sharp commercial solution, and it is not a workforce strategy. Selecting the wrong pathway can result in refusal and reputational exposure.
In 2026, this is one of the visas the Department now scrutinises heavily. Where a role looks like ongoing employment rather than a genuinely temporary specialist engagement, the Department generally expects you to use the Skills in Demand (Subclass 482) visa framework instead. You must also show that you have a genuine need for someone with this specific expertise and that local citizens and permanent residents are not being overlooked for the position.
💡 The visa delivers its promised speed only when the evidence of your genuine, temporary, specialised need is built properly first. The fast option rewards the employer who does the unglamorous groundwork, and it punishes the one who treats that groundwork as a formality.
Key Point: The Department scrutinises Subclass 400 visa applications heavily in 2026, if the engagement resembles ongoing employment, the Subclass 482 visa pathway is the appropriate instrument.
Subclass 400 vs Subclass 482 visas: How to Choose
Choosing between the Subclass 400 and the Subclass 482 visas comes down to the true shape of your need rather than the speed you would prefer.
If your requirement is short, specialised, and finite, the 400 is often the right instrument. If you need someone for an ongoing role, if the work will realistically outlast six months, or if you are quietly hoping the arrangement becomes permanent, you are looking at the 482 visa pathway, and the honest advice is to plan for it properly from the start.
It is worth noting that the barriers on the 482 visas continue to rise. The Core Skills Income Threshold increased by 3.9 percent on 1 July 2026, taking the mandatory minimum package for most nominations from AUD 76,515 to AUD 79,423. That rising threshold makes it more important, not less, to match the instrument to the actual need rather than defaulting to whichever route feels familiar.
Key Point: The 400 visa fits short, finite, specialised needs, the 482 visa fits ongoing roles. Choosing the right pathway from the start carries real financial weight.
Where Do Subclass 400 visa Applications Actually Fail?
The most common reason a Subclass 400 visa application comes undone is thin or poorly structured evidence of business need. A generic job description, a vague explanation of why the work is specialised, or a loose account of why the skill is unavailable locally will each raise the risk of refusal.
Applications submitted complete with proper documentation are approved at a rate of around 90 percent, whilst incomplete or poorly justified applications drive that figure down sharply. The criteria themselves are not the true bottleneck. The bottleneck is whether the evidence to prove those criteria actually exists and has been assembled clearly.
This is precisely where expert advice pays for itself. Building a detailed, credible business justification, framing the specialist requirement so it withstands scrutiny, and demonstrating the genuinely temporary nature of the engagement is the work, and it is the difference between a two-week approval and a costly detour.
Key Point: A 90 percent approval rate is achievable, but only with complete, well-structured evidence. The criteria are not the barrier; the quality of the documentation is.

The Short Version
The Subclass 400 is a precise instrument for a genuinely temporary and specialised gap. It offers you real speed, no sponsorship accreditation burden, modest cost, and welcome flexibility for project-based and niche needs, all of which make it a strong choice when your situation genuinely fits.
Its promised speed, though, belongs to the employer honest enough to match it to a real need and disciplined enough to prove that need with proper evidence. The right question is not how quickly you can bring someone in. It is whether your situation is genuinely the narrow shape this visa was designed for.

Frequently Asked Questions
How long does it take to process a Subclass 400 visa application?
Well-prepared applications with complete documentation are typically processed within two weeks. A thin or poorly evidenced application will take longer, or result in a refusal.
Do I need to be an approved sponsor to use the Subclass 400 visa pathway?
No. The Subclass 400 visas does not require formal sponsorship accreditation, which is one of its key advantages over longer pathways such as the Subclass 482 visas. Your organisation still provides a supporting statement, yet the accreditation burden is removed entirely.
Can the Subclass 400 visa be extended beyond six months?
It cannot be extended beyond six months. If the work continues past that point, you would need to submit a new application rather than renew the existing one, and at that stage, the Department is likely to question whether the engagement is genuinely temporary.
Does the Subclass 400 visa lead to permanent residence?
No. The Subclass 400 visa does not provide a pathway to permanent residence. If permanent residency is the longer-term goal for the individual, a different visa stream is the appropriate starting point.
What is the application fee for the Subclass 400 visa?
The base visa application charge is AUD 535 for the primary applicant. This is significantly lower than employer-sponsored pathways such as the Subclass 482, which carry nomination fees and the Skilling Australians Fund levy on top.
What makes a Subclass 400 application fail?
Thin or poorly structured evidence of business need is the most common cause of refusal. A generic job description or a vague account of why local workers are unavailable will raise the risk of rejection considerably. The criteria themselves are not the bottleneck, the quality of the documentation is.
How is the Subclass 400 different from the Subclass 482?
The Subclass 400 visa is for short, finite, highly specialised engagements of up to six months. The Subclass 482 suits ongoing roles where the worker will be employed for an extended period. With the 482's Core Skills Income Threshold rising 3.9 percent on 1 July 2026, selecting the correct pathway from the start carries real cost implications.
What evidence do I need to support a Subclass 400 application?
You will need a detailed business justification explaining the specific task, why it requires highly specialised expertise, why that expertise is not available in the local labour market, and why the engagement is genuinely temporary. A well-structured, credible justification is the single greatest factor in whether an application succeeds.
