Where Do Subclass 151 Cases Actually Fail in 2026? A Risk Checklist

Cases for the Former Resident visa (Subclass 151) fail, in practice, at a short list of threshold tests rather than at the edges: you must fit the long residence or defence service category, every long residence condition (at least nine years in Australia as a permanent resident before turning 18, under 45 when you apply, never an Australian citizen, and ties kept after permanent residence ended) must hold on the date you lodge, and any included family member who fails health, character or passport requirements sinks the whole application under the "one fails, all fails" rule. According to the Department of Home Affairs' Former Resident visa (Subclass 151) official page, checked as of August 2026, and the criteria in the Migration Regulations 1994 together with the Department's PAM3 procedural guidance, the refusal points sit in the definitions and the family-unit rule, while a less obvious hazard is ties that lapsed and were later picked up again.

Which of the two applicant categories are you actually in?

Subclass 151 is a permanent Special Eligibility (Class CB) visa for people who qualify either as a long residence applicant or as a defence service applicant. Clause 151.212 of the Migration Regulations 1994 requires the applicant to be one or the other; if you meet neither definition, there is no other pathway inside this subclass. The official page repeats the same split and sets out the two sets of criteria separately, so the first task before preparing any evidence is deciding which limb you are standing on.

What does the long residence requirement ask you to prove?

The long residence limb has four elements, and all of them must be true at the time you apply. If you are 18 or older, you must have spent at least nine years in Australia as a permanent resident before you turned 18; if you are under 18, you must have spent at least half of your life in Australia as a permanent resident. You must be younger than 45 at the time of application, you must have never been an Australian citizen, and after you stopped being a permanent resident you must have kept close business, cultural or personal ties with Australia — the official page includes regular contact with relatives or friends, frequent visits, owning property, or having active business interests.

The documents the official page asks you to gather for this limb cover both the residence history and the ties: passport pages showing dates of arrival in and departure from Australia, school attendance records, evidence of business or property ownership, social or professional memberships, personal correspondence, records of visits, and proof of an ongoing and active economic or business interest. Non-English documents generally need translation, and only certified copies should be sent with a paper application.

What does the defence service requirement ask you to prove?

For the defence service limb, you must show that before 1981 you either completed at least three months of continuous Australian defence service, or were discharged from the Australian Defence Force before three months of service because you were medically unfit as a result of that service. There is no age requirement for this category, unlike the long residence limb. The evidence listed on the official page is simply proof of service with the Australian Defence Forces before 1981, supported by the standard identity documents.

PAM3 adds practical detail to this limb: the service should generally be as a member of the Permanent Forces and should be continuous, and reserve or emergency forces usually do not qualify, although there can be exceptions where a reserve unit included regular members. Because these details come from policy guidance rather than the face of the official eligibility page, the current policy should be confirmed against the official page before you rely on a marginal service record.

Which failures can never be fixed after you lodge?

The refusal points divide into two kinds, and the difference decides whether a case can still be saved. Objective shortfalls — being 45 or older on the lodgement date, falling short of the nine years' residence, having acquired Australian citizenship at any time, or not meeting the defence service definition — are assessed from the facts as they stood when the application was made. These leave no room to remedy the substance after lodgement, because the criterion was either met or it was not.

By contrast, where the decision-maker's concern is that your evidence is weak or that a declaration is doubted — for example, thin proof of continuing ties, or a question over whether you ever held citizenship — the general procedure is to raise the concern with you and allow a response before a refusal is recorded. This is why an agent's pre-lodgement review concentrates on the objective dates and definitions first: those are the ones a later request for more information cannot repair.

Where does "one fails, all fails" catch applicants out?

The regulations apply a "one fails, all fails" principle to members of the family unit through clauses 151.226–151.227B, and PAM3 repeats it. If a partner or dependent child included in the application does not satisfy the public interest criteria, special return criteria, health requirement or character requirement, the main applicant cannot be granted even if the main applicant's own record is clean.

The health standard is not the same for everyone in the family. Family members who apply from outside Australia are tested against PIC 4005, which has no waiver, while an onshore long residence applicant or a defence service applicant and their family are tested against PIC 4007, where a waiver may be considered. Character applies to the applicant and any family members aged 16 or over, and the official page tells applicants not to arrange police certificates until they are asked. Secondary applicants are also expected to hold a valid passport under PIC 4021, unless requiring one would be unreasonable.

What is the hidden trap: ties that stopped and started again?

The official page asks you to have "kept" close business, cultural or personal ties after you were no longer a permanent resident, and PAM3 treats that word as a continuity test. The guidance expects the tie to have existed before permanent residence ceased and to have continued through to the application; if contact, visits or business interests lapsed for a period and were only revived later, the decision-maker may find the tie was not kept, even though ties plainly exist on the day you lodge.

The evidence burden is not identical for every applicant. PAM3 expects less from someone who left Australia as a child, where school letters or family records may be enough, and more from an adult who left after permanent residence ended, where correspondence, visit records, property ownership and economic activity are expected. The practical answer is a dated timeline running from before permanent residence ended to the application date, with an explanation for any gap: the gap itself is the risk, not the current snapshot of ties.

What does the pre-lodgement risk checklist look like?

Treat the table below as general information only — it is not personalised advice on your case, and the current official pages and the Migration Regulations 1994 remain the reference for what applies to you, so confirm details there or with a qualified professional.

Check	What is required	Type of failure
Category	You are a long residence applicant or a defence service applicant (reg 151.212)	Objective — no category, no visa
Long residence: residence	9+ years in Australia as a permanent resident before turning 18, or half of life if under 18	Objective — shortfall cannot be cured
Long residence: age	Younger than 45 on the date you apply	Objective — lodgement date controls
Long residence: citizenship	Never been an Australian citizen; acquiring and then losing citizenship also fails the definition	Objective
Long residence: ties	Close business, cultural or personal ties kept after permanent residence ended; PAM3 expects continuity and warns that a lapse-then-resume pattern may fail	Evidence or continuity — may be put to you first
Defence service	Before 1981: 3 months continuous ADF service, or medical discharge inside 3 months due to service; PAM3 expects Permanent Forces and continuity	Objective if the definition is not met
Lodgement method	Paper Form 47SV, all applicants together, mailed to GPO Box 9984 Sydney, not online or in person, not in immigration clearance, charge paid first, certified copies only	Invalid application if steps are incomplete
Onshore timing	If applying in Australia without a substantive visa, Schedule 3 criterion 3002 must be met (28 days under the Migration Regulations 1994)	Objective timing bar
Health	Applicant and included family meet health; offshore family tested against PIC 4005 (no waiver), onshore or defence against PIC 4007 (waiver possible)	One fails, all fails
Character	Applicant and family aged 16+ meet character; police certificates only when asked; military records if anyone served	One fails, all fails
Family passports	Secondary applicants hold a valid passport (PIC 4021) or show that requiring one is unreasonable	One fails, all fails
Assurance of support	If the Minister requires it, an approved assurance of support is needed (reg 151.229B)	Discretionary requirement
History and debt	No unpaid debt to the Australian Government; past cancellation or refusal is weighed, and special return criteria 5001, 5002 and 5010 may apply	Weighed, and can be a bar

One consequence of the paper-only rule is that an incomplete lodgement step can make the application invalid, which means it is not processed at all. Travel during processing is also a refusal risk in its own right: if you applied in Australia, the visa cannot be granted while you are outside Australia, and if you applied outside Australia, the visa cannot be granted while you are in Australia.

What should you line up before the envelope goes out?

Start with the category evidence: school records, passport arrival and departure pages, permanent residence proof, or Australian Defence Force records for the defence limb. Build the ties evidence as a dated timeline, with correspondence, visit records, property or business documents, and a written explanation for any period when the tie was weaker. Collect identity documents for each applicant — passport pages with photo, personal details, signature and issue and expiry dates, a national identity card if there is one, and proof of any change of name — and prepare certified copies rather than originals.

For family members, assemble relationship evidence such as birth or marriage certificates, and for adult dependants the documents about their other relationships and character. Do not arrange police certificates until the Department asks, but if anyone included in the application has served in the armed forces of any country, certified copies of military service or discharge papers form part of the character documents. If someone is helping with the application, only a registered migration agent, a legal practitioner, or an exempt person can give immigration assistance, and the nomination is made on Form 956 or Form 956A sent with the paper application; anyone can be appointed purely to receive correspondence.

Frequently Asked Questions

What is the "one fails, all fails" rule in Subclass 151?

It means any member of the family unit included in the application who does not meet health, character, passport or special return criteria will cause the whole application, including the main applicant's case, to be refused. The principle comes from clauses 151.226–151.227B of the Migration Regulations 1994 and is repeated in PAM3. If you apply from outside Australia, family members who are not coming to Australia may also have to meet health and character requirements.

Can a Subclass 151 application be fixed after lodgement if the evidence is thin?

It depends on whether the shortfall is an objective criterion or a concern about evidence. Shortfalls such as being 45 or over at lodgement, less than nine years' residence before turning 18, or having ever acquired Australian citizenship are decided from the facts at the time of application and usually leave no room to remedy. Where the decision-maker doubts your ties evidence, identity or citizenship declaration, the general procedure is to raise the concern and allow a response before refusing.

Does a break in contact with Australia ruin a Subclass 151 case?

A long gap can be fatal because the requirement is to have kept close business, cultural or personal ties after permanent residence ended, and PAM3 treats the tie as needing to run continuously from before residence ceased to the application. Ties that lapsed and were later resumed may be judged as not "kept", so the dated timeline matters more than the current snapshot. Adult applicants who left after permanent residence ended face a higher evidence expectation than those who left as children.

How old can I be when I apply?

For the long residence requirement, you must be younger than 45 at the time you apply, and the test is applied on the lodgement date. There is no age requirement for the defence service category, which instead requires service before 1981 meeting the three-month continuous service or medical discharge condition.

Why must Subclass 151 be applied for on paper?

The official page states the application must be made on paper using Form 47SV, with all applicants on the one form, lodged with the Sydney office by mail, and it cannot be made online or in person. If any lodgement step is incomplete the application may be invalid and will not be processed, so the charge must be paid first and only certified copies, not originals, should be sent. You must not be in immigration clearance when you apply, and you can be in or outside Australia.

Who is allowed to give immigration assistance on this visa?

Only a registered migration agent, a legal practitioner, or an exempt person can give immigration assistance on the application. Anyone can be appointed just to receive documents on your behalf. The nomination is made on Form 956 for assistance or Form 956A for an authorised recipient, sent with the paper application.
