Why Are Subclass 151 Applications Refused in 2026? Top Grounds
What most often sinks a subclass 151 (Former Resident) application, and which of those refusal grounds you can still answer.
Subclass 151 (Former Resident) applications are refused in a short, predictable list of places: time spent in Australia before turning 18, age on the day you lodge, whether your ties to Australia genuinely continued, whether you ever acquired Australian citizenship, whether your defence service fits the definition, and whether every family member included in the application clears health and character. The Department of Home Affairs' Former Resident visa (subclass 151) page, as published as at August 2026, states the residence, age, citizenship and ties requirements directly; the remaining grounds come from the criteria structure in the Migration Regulations 1994 and the department's Procedures Advice Manual (PAM3). This article is general information about how the criteria work, not advice on your own circumstances — anything that turns on your specific history should be checked against official information or with a qualified professional.
The Department does not publish a ranked breakdown of refusal reasons for this visa, so the order below is not a statistic. It follows the order in which the criteria themselves eliminate applicants, which is also the order in which you should test your own case before you post anything.
Which of the two applicant categories are you actually in?
Subclass 151 sits in the Special Eligibility (Class CB) class, and clause 151.212 requires you to be either a long residence applicant or a defence service applicant. There is no third entry point, and applications that fit neither are refused on that basis alone rather than being assessed against a general "connection to Australia" test. Which category you are in also decides which of the grounds below apply to you, so it is the first thing to settle.
| Long residence applicant | Defence service applicant | |
|---|---|---|
| Core test | At least nine years in Australia as a permanent resident before turning 18 (or, if under 18 when applying, at least half of your life as a permanent resident) | At least three months of continuous Australian defence service before 1981, or discharge before three months because you were medically unfit due to that service |
| Age at application | Must be under 45 | No age requirement |
| Australian citizenship | Must never have acquired it | Not part of the test |
| Ties to Australia | Must have kept close business, cultural or personal ties since ceasing to be a permanent resident | Not part of the test |
| Document focus | Residence records, then post-departure ties | Service and discharge records |
Did you actually spend nine years here as a permanent resident before you turned 18?
The requirement is nine years in Australia as a permanent resident before your 18th birthday, not nine years in Australia generally. Time spent here on a temporary visa, or before permanent residence was granted, does not fill the quota. Applicants who are themselves under 18 when they apply are measured differently: at least half of their life so far must have been spent in Australia as a permanent resident. PAM3 describes the calculation as being made on a calendar basis.
The evidence that settles this is documentary, not narrative: passport pages showing arrival and departure dates, school attendance records or Department of Education records, and address history. A statutory declaration describing a childhood in Australia will not carry the point on its own. Because the test is measured on facts that were fixed years ago, a shortfall here is one of the hardest refusals to answer — nothing you do after lodging changes the count.
Are you still under 45 on the day you apply?
Long residence applicants must be younger than 45 at the time of application. The date that matters is the lodgement date, which for a paper application is when the Department receives it, not when you started preparing it. Turning 45 while the application is being processed does not, on the wording of the criterion, undo eligibility; applying after your 45th birthday does. A certified birth record settles the point.
The defence service route carries no age requirement at all, so a defence service applicant who is well past 45 is not excluded by age.
Can you show the ties continued, rather than that they once existed?
Long residence applicants must have kept close business, cultural or personal ties with Australia after they stopped being a permanent resident. The official page gives the working examples: regular contact with relatives or friends, frequent visits, owning property, and having active business interests. Documentary proof runs along the same lines — correspondence with relatives or friends in Australia, records of visits, evidence of property or business ownership, professional or social memberships, and proof of an economic or business interest that is ongoing and active rather than nominal.
PAM3 adds two qualifications that catch applicants out. First, the ties are expected to have existed before permanent residence ceased and to have continued through to the application; a period in which contact lapsed and was later revived is treated as a problem, not as a neutral gap. Second, the evidence expected scales with age at departure: someone who left Australia as a child is held to a lighter standard, while an adult who left as an adult is expected to produce substantially more — correspondence, visit history, property holdings, economic activity, usually presented with a timeline.
This ground is also the one with the most room to respond. Where the concern is that the evidence is thin rather than that a hard criterion is missed, the Department's general practice under section 56 of the Migration Act 1958 is to invite further information or comment before deciding. A weak ties file is therefore worth building properly at lodgement rather than leaving to be patched later.
Did you ever acquire Australian citizenship, even if you no longer hold it?
The criterion is "have never been an Australian citizen", and the test is whether you acquired citizenship at any time, not whether you hold it now. Someone who acquired citizenship as a child and later lost or renounced it does not meet the long residence definition, whatever their residence history; other pathways, such as a resident return visa or resumption of citizenship, are separate questions.
If the Department's records raise a doubt, PAM3 directs the officer to check with the Citizenship Help Desk and to give the applicant an opportunity to clarify rather than refuse on the spot. If your own history is uncertain, resolving it before you lodge is cheaper than resolving it after a refusal.
Does your defence service fit the definition, or only resemble it?
For the defence route, the official page requires that before 1981 you either completed at least three months of continuous Australian defence service, or were discharged before completing three months because you were medically unfit as a result of that service. "Continuous" is doing real work: PAM3 treats service as needing to run without interruption, and treats membership of the regular or permanent forces as the norm, with reserve or emergency force service generally falling outside unless the unit itself comprised regular members. Periods of national service around changes to the scheme need particular care, so check the current Department of Home Affairs guidance and the Migration Regulations 1994 for how your service period is treated.
The practical failure mode is documentation. Service records and discharge papers that do not state dates, continuity, or the nature of the engagement leave the decision maker with nothing to assess. Certified copies of military service records are required for anyone in the application who has served in the armed forces of any country, not only for the person claiming the defence criterion.
Could a family member refuse the whole application?
Yes. Clauses 151.226 to 151.227B apply a "one fails, all fail" rule: if any family member included in the application does not satisfy the public interest criteria or the special return criteria, the application as a whole cannot succeed, even where the main applicant is plainly qualified.
Three areas drive this. Health: an offshore long residence applicant faces public interest criterion 4005, which carries no waiver, while an onshore long residence applicant and defence service applicants are assessed under 4007, where a waiver can be considered. Character: everyone aged 16 or over must meet the character requirement, and criterion 4001 applies to all applicants. Documentation: secondary applicants are expected to hold a valid passport under criterion 4021, with the exemption for it being "unreasonable" to require one applied narrowly, and where children are involved the decision maker must be satisfied about custody arrangements and the best interests of the child under clauses 151.228 and 151.325. Family members can be added before a decision is made using Form 1436, with the additional charge payable, but they cannot be added afterwards to repair a refusal.
Where else does the file fail before any of this is weighed?
Several refusals happen before the substance is reached at all.
- Invalid lodgement. Subclass 151 is a paper-only visa. All applicants apply together on one Form 47SV, lodged with the Sydney office at GPO Box 9984, Sydney NSW 2001; online and in-person lodgement are not available, and you cannot apply while in immigration clearance. The application charge must be paid before the application is sent, or it will not be processed. Send certified copies only, never originals, and keep your own copy of everything.
- No substantive visa onshore. An onshore applicant who no longer holds a substantive visa must also satisfy the Schedule 3 criteria, including criterion 3002. The time limit set by criterion 3002 is applied strictly, so check the current Schedule 3 text in the Migration Regulations 1994 for the period that applies to your situation.
- Debt to the Australian Government. Any debt owed by you or an included family member must have been repaid or be subject to a formal arrangement to repay.
- Immigration history. A cancelled visa or a previously refused application is taken into account, and the special return criteria (5001 and 5002 for onshore applicants, with 5010 added offshore) can independently bar the grant.
- Assurance of support. This is discretionary, but if the Department asks for one it must be approved through the social services agency before the visa can be granted.
Which grounds are final, and which give you a chance to respond?
The residence period, age, citizenship history and service record are measured on facts fixed at the time you lodge. If one of them is short, there is nothing to supplement and no later event that repairs it.
Ties evidence, identity documents and most family-member documentation sit differently: they are questions of proof, and the Department's practice is to invite further information or comment under section 56 of the Migration Act 1958 before relying on adverse material. That is why the ties section of a 151 application deserves most of the preparation effort.
After a refusal, the decision letter states the reasons and whether you have a right to merits review; A 21-day period for applying to the Administrative Appeals Tribunal, running from when you receive the refusal, is commonly cited, so treat the letter and the tribunal's current official information as authoritative on timing. A criterion with no waiver, such as the offshore health criterion 4005, limits what review can achieve. The application charge is not refunded if the application is refused.
Frequently Asked Questions
Is there an official list of the most common subclass 151 refusal reasons?
No ranked official list is published for this visa. The grounds covered above are drawn from the criteria themselves — the Department of Home Affairs' Former Resident visa (subclass 151) page, the Migration Regulations 1994 and PAM3 — and are ordered by how the criteria eliminate applicants, not by frequency statistics.
How is the nine years before turning 18 counted?
It is nine years spent in Australia as a permanent resident before your 18th birthday, calculated on a calendar basis, and time in Australia on a temporary visa does not count. If you are under 18 when you apply, the test is instead at least half of your life spent in Australia as a permanent resident.
I lost contact with Australia for several years and then reconnected — is that fatal?
It is a serious risk rather than an automatic refusal. PAM3 expects ties to have existed before permanent residence ceased and to have continued to the application, and it holds adults who left Australia as adults to a higher evidentiary standard. Presenting a dated timeline with correspondence, visit records, property or business interests gives the decision maker something to weigh.
I became an Australian citizen as a child but no longer hold it — can I still qualify?
Not as a long residence applicant, because the test is whether you acquired citizenship at any time, not whether you hold it now. Whether another pathway is open, such as a resident return visa or resumption of citizenship, is a separate question.
Does reserve service, or service shorter than three months, count for the defence route?
Only if it meets the definition: at least three months of continuous Australian defence service before 1981, or discharge before three months because you were medically unfit as a result of that service. Reserve and emergency force service generally falls outside unless the unit comprised regular members, and continuity matters, so the service record needs to state dates and the nature of the engagement.
Can my partner's or child's health or character problem refuse my application?
Yes. The "one fails, all fail" rule in clauses 151.226 to 151.227B means any included family member who does not satisfy the health or character criteria defeats the whole application. Character applies to everyone aged 16 or over, and offshore long residence applicants face the health criterion that carries no waiver.
Can I lodge a subclass 151 application online?
No. You must apply on paper using Form 47SV, lodged with the Sydney office, and you cannot lodge in person, online, or while in immigration clearance. The charge must be paid before the application is sent, and only certified copies should be posted.
