Why Short Stay Specialist visa (subclass 400) applications get refused
For an employer, a 400 refusal is more than one lost application. Below are six reasons applications fail, what a refusal means for your company’s later applications, and what to do before relodging.
The cost
What a refusal actually costs you
More than the application fee and the delay.
A refusal doesn’t disappear: it becomes part of the specialist’s history on later applications, and the Department looks at how a business uses the 400 over time. For a business that mobilises specialists regularly, one avoidable refusal can make later applications harder, which is why we would rather tell you at the triage call that a case will not stand than lodge it and hope.
Six reasons
The six reasons applications fail
- The work isn’t accepted as specialised
- The role doesn’t read as short-term
- “Specialist skills not available in Australia” isn’t evidenced
- The contractual chain is inconsistent
- Cumulative stay and repeat applications
- The commercial case is asserted, not shown
Reason 1
The work isn’t accepted as specialised
A job title doesn’t make the work specialised. What usually shows it is the detail of the task: what is being done and, for equipment work, the make and model, the OEM authorisation or certification the task calls for, and any warranty condition that names who may do the work. Describe the task in general terms and there is nothing specialised for the application to rest on.
Reason 2
The role doesn’t read as short-term
A short visit isn’t the same thing as short-term work. What usually shows the difference is an end that comes from the job itself: a shutdown or a commissioning window finishes, and the schedule, the work pack and the contract say when. A role with no end date, or a first visit that is the start of something longer, can look ongoing however short the trip. If the role is ongoing, the 400 is the wrong instrument: the 400 vs 482 guide compares the two.
Reason 3
“Specialist skills not available in Australia” isn’t evidenced
This phrase does the heaviest lifting in the whole application, and it can’t be left as an assertion.
There’s no formal labour market testing for a 400. The application still has to show why the skills aren’t readily available in Australia, and certification, OEM authorisation and licensing usually show that better than a job ad.
“We couldn’t find anyone locally” is an assertion. A record of what was advertised, who responded, and why they did not meet the certification requirement is evidence. That gap is where a weak application is exposed.
Reason 4
The contractual chain is inconsistent
A specialist can be employed by an overseas OEM, engaged through a contractor and working on an operator’s plant. That is common on a 400. The trouble starts when the invitation letter, the contract and the specialist’s employment evidence describe the arrangement three different ways. Establish at the start who is inviting the specialist, who employs them and who directs the work on site, and describe that arrangement accurately and consistently in every document.
Reason 5
Cumulative stay and repeat applications
In September 2024 the Department of Home Affairs began applying the 400 more strictly. Longer stays, repeat visits, large groups and roles that look ongoing get closer scrutiny, so every application needs evidence that the work is specialised, short-term and can’t be sourced locally.
Normally up to three months in any 12-month period, counting every 400 stay with any employer. Up to six months only in exceptional circumstances, on strong evidence. A specialist who has already spent time in Australia on a 400 in the last 12 months may be granted only the balance, so offshore and FIFO rosters that add up to more than three months a year need a different visa.
The pattern that causes problems is a regular one: the same OEM technician returning for every outage, the same specialist on every shutdown. Each individual application may be defensible. The pattern reads as an ongoing working relationship, which is 482 territory.
If your specialist has been to Australia on a 400 in the last twelve months, that changes how the case has to be built. Say so at the first call.
Reason 6
The commercial case is asserted, not shown
Saying the work is urgent and important isn’t the same as showing what the delay costs.
Cost of outage per day. Contract penalties at stake. Production consequence of the date slipping. Those figures come from your business, and presenting them properly is where our principal’s corporate finance background does the work.
An application that quantifies the consequence is a materially different document from one that describes it.
After a refusal
What to do if you’ve already been refused
First, understand precisely why: the reasons given matter enormously to what is possible next, and a refusal on evidentiary grounds is a different problem from one on eligibility grounds.
Do not immediately relodge the same case with the same material. Get advice before relodging.
Depending on the grounds there may be options: a properly evidenced fresh application or a different instrument. There may also not be, and we will tell you that.
