Can Three Months of Australian Defence Service Get You Subclass 151 in 2026?
Yes — three months counts, and it is the whole test for the defence route. According to the Australian Department of Home Affairs page on the Former Resident visa (Subclass 151), read as of August 2026, a person who completed at least three months of continuous Australian defence service before 1981 meets the defence services requirement, and there is no other numeric target behind it. This article is general information rather than advice tailored to one person's record, so the wording on the official page — and any professional help you choose to take — should be what you rely on for an actual application.
What exactly does the three-month rule say?
The Subclass 151 (Former Resident) visa accepts two quite different qualification routes: a long residence requirement and a defence services requirement. Only one has to apply. The defence route asks that, before 1981, you met one of these conditions:
- completed at least 3 months of continuous Australian defence service; or
- were discharged from the Australian Defence Force before completing 3 months of service because you were medically unfit as a result of that service.
Two conditions sit inside the first bullet and are easy to gloss over. The service must have occurred before 1981, and it must have been continuous. Nothing in the official text requires the service to have been overseas, combat-related, or recent in any sense — a person who served decades ago is still measured against the same sentence.
PAM3 narrows the relevant service window further, to service on or after 26 November 1964 and before 19 January 1981, and treats the three months as a period served as a member of the Permanent Forces. That narrower framing is departmental guidance rather than legislation, so where the two descriptions differ, the current Home Affairs page governs; anything drawn from the guidance layer should be re-checked against what the Department publishes now.
What if you served less than three months?
Short service fails the main test, but it is not automatically the end. The second condition exists precisely for this case: you can still meet the requirement if you were discharged before reaching three months because you were medically unfit because of your Australian defence service. The causal link is doing the heavy lifting here. A discharge for a medical condition with no connection to service, or a discharge for administrative or disciplinary reasons, does not fit either condition.
That link has to be shown in documents rather than asserted. The evidence that matters is military medical records tying the discharge directly to service, which in practice means discharge papers and service medical documentation that speak to each other. An honourable short service with no medical paper trail has no obvious path through this requirement.
For orientation, here is how the common situations line up:
| Situation | Meets the defence services requirement? |
|---|---|
| 3+ months continuous service, before 1981 | Yes, on the face of the requirement |
| Discharged under 3 months, medically unfit due to service | Yes, under the second condition, if documented |
| Discharged under 3 months for reasons unrelated to service | Not on either condition |
| Service with gaps, totalling 3+ months across separate periods | Continuity is in doubt; assessed on the record |
| Reserve-only service with no Permanent Forces membership | Usually outside the requirement, per guidance, with limited exceptions |
Does reserve or interrupted service count?
This is where the requirement is least forgiving and least mechanical. The Home Affairs wording attaches "continuous" to the three months, so intermittent service that adds up to ninety-odd days across separate engagements is not the same thing. PAM3 says service does not have to be full-time to count, but has to be unbroken, and that no fixed definition of "continuous" is set out — decision makers weigh the actual service record. So a gap-filled record is genuinely uncertain rather than clearly refused.
Reserve service is more constrained. PAM3 describes qualifying service as service as a member of the Permanent Forces, with reserve or emergency force service normally falling outside the requirement; a narrow exception is noted where a reserve unit itself contained permanent members. Since that guidance is not binding law and the official page does not spell out these categories, anyone whose record is reserve-based should expect the membership character of their unit to be the deciding fact, and should verify the current published position before relying on the exception.
What else must a defence route applicant satisfy?
Meeting the defence services requirement establishes which route you are on — it does not end the assessment. Still applying are:
- Age. There is no age requirement for the defence services requirement. The under-45 rule on the official page is tied specifically to the long residence requirement, so it does not follow a defence applicant. This is one of the few places where the two routes differ sharply.
- Health. You and family members applying with you must meet the health requirement. The Migration Regulations 1994 point defence service applicants (and onshore long residence applicants) to public interest criterion 4007, which can be waived, rather than the stricter 4005 that applies to offshore long residence applicants.
- Character. Applicants aged 16 and over must meet the character requirement; members of the family included in the application can also be assessed.
- Debt and immigration history. Any debt to the Australian Government must be repaid or be subject to a formal repayment arrangement, and a history of cancelled visas or refused applications is taken into account.
- Assurance of support. You may be asked to provide one.
Note also what does not apply to you on this route: the never-held-Australian-citizenship condition, the nine-years-in-Australia-before-18 condition, and the ongoing business, cultural or personal ties condition are all features of the long residence requirement.
How do you prove the service?
The official document guidance asks for evidence of service with the Australian Defence Forces before 1981, and separately notes that anyone included in the application who has served in the armed forces of any country should provide certified copies of military service record or discharge papers. Because the decision turns on dates, continuity and membership type, the useful record is one showing start and end dates, the nature of the engagement, and — for the medical exception — the medical basis for discharge.
Two practical features of this visa often surprise applicants. It is paper-only: all applicants use one Form 47SV (Application for special migration to Australia), lodged by post with the Department's Sydney office, and it cannot be lodged in person or online (payment itself is made online in ImmiAccount). And where you apply has consequences at decision time — the visa cannot be granted while you are in Australia if you applied outside it, and vice versa.
Frequently Asked Questions
Does service have to be exactly three calendar months, or longer?
The requirement is "at least" three months, so longer service satisfies it as comfortably as exactly three months does for this route. What matters is that the period was continuous and occurred before 1981.
I was discharged after six weeks for a back injury — does that qualify?
It can, only if the discharge was because you were medically unfit as a result of your Australian defence service. Military medical documentation linking the condition to service is what puts the case inside that condition rather than outside it.
Can part-time or interrupted service be counted as continuous?
PAM3 says service need not be full-time but must be unbroken, and that "continuous" has no fixed definition. A record with gaps is therefore assessed on its facts rather than decided by a simple arithmetic rule.
Is there an age limit on the defence route?
No. The official page states there is no age requirement for the defence services requirement; the under-45 rule applies only to applicants relying on the long residence requirement.
If I qualify through defence service, do I still need to prove ties to Australia?
No. Keeping close business, cultural or personal ties with Australia is part of the long residence requirement, and the same is true of the never-held-citizenship and nine-years-before-18 conditions.
Can I add family members after lodging?
Yes, before a decision is made, using Form 1436 (Adding an additional applicant after lodgement), together with relationship evidence, supporting documents and the additional application charge.
