How Do I Add a Child to My Australian Partner Visa Application in 2026?

Updated 2026-10-11 · General information, not migration advice · Run by the Arrivau team

If your child arrives while your Partner visa application is still being decided, you do not lodge a brand-new application for them. According to the Australian Department of Home Affairs' Partner Visa Frequently Asked Questions (FAQs) page, as of October 2026, you go to the web page of the visa you applied for, open the step-by-step tab, choose after you apply, and then choose add family members. This article is general information only, not advice tailored to one family; the step that fits your situation should always be confirmed against the current official page and, where your circumstances are complicated, with a suitably qualified professional.

Where exactly is the "add family members" step?

The Home Affairs FAQ gives the path as a short sequence. Open the visa page for your subclass. Select the step-by-step tab. Go to "after you apply". Select "add family members". Follow the prompts that appear there.

That is the whole navigation. There is no separate online form named in the Department's guidance for this step — it sits inside the step-by-step view of each Partner visa page.

Which visa page should I open?

Use the page for the subclass you actually applied for. The Department lists the same path for all five family-stream subclasses:

Partner visa (subclass 820) — the temporary onshore visa
Partner visa (subclass 801) — the permanent onshore visa
Partner visa (subclass 309) — the provisional offshore visa
Partner visa (subclass 100) — the migrant offshore visa
Prospective Marriage visa (subclass 300)

If your application covers a paired subclass — 820 and 801, or 309 and 100 — the FAQ treats the two as one application in other contexts, such as withdrawal, so it is worth checking the guidance under both subclass pages before you act.

Does it matter that my child was born after I lodged?

The published guidance sets out one route for adding a child to a Partner visa application, and it does not split that route by when the child was born. What matters in the Department's instructions is which subclass you are on, and whether you are using the step-by-step "after you apply" path or the separate route described below for permanent-stage cases.

A practical consequence follows from this: the child's details and documents are added to the existing application rather than replacing it. Your application ID stays the same, and you continue to track progress in ImmiAccount.

Where do the supporting documents go?

Documents are attached through ImmiAccount. The FAQ points applicants to the "Attach documents to your application" instruction under the applying-online section of the Home Affairs site, and notes that you provide further information or documents by attaching them to your ImmiAccount.

Health checks follow their own timing rule. You can complete health examinations after you apply, and the results are valid for 12 months from the time you complete the examinations; if you are asked to sign a health undertaking, that is valid for 6 months. The Department may ask you to provide them again if they expire before it decides your visa.

What if I already hold a 309 or 820 and my child needs to join me?

There is a second route, and it applies specifically to adding a child to a subclass 801 or subclass 100 application. The FAQ states that if you hold a temporary Partner visa (subclass 820 or 309), your child can apply for a Dependent child visa (subclass 445). Once your child holds that visa, the Department directs you to the instructions under "When you have this visa" on the Dependent child visa (subclass 445) page for adding them to your Partner application.

So the decision point is straightforward. If your Partner application is still undecided, use the step-by-step "after you apply → add family members" path. If you already hold the temporary visa and are moving toward the permanent stage, the 445 route is the one the Department describes.

Will adding a child change how long my application takes?

Partner visa applications are processed under Ministerial Direction 117. Applications are generally assessed in the order received, with highest priority given to onshore Partner visa (subclass 820 and 801) applications. Lower priority is given to offshore applications for the Prospective Marriage visa (subclass 300) and the Partner visa (subclass 309 and 100), and those applications are likely to experience longer processing times.

For an indication of timeframes, the Department points to its visa processing time guide tool, which shows the processing times for recently decided applications and is a guide only, not specific to your application. The FAQ also advises applicants not to contact the Department while an application is still within the standard processing time, and directs them to ImmiAccount to check status and whether all supporting documents have been provided.

When does the permanent stage come into the picture?

The permanent Partner visa (subclass 801 or 100) has its own eligibility gate. Two years must have passed since you applied for the temporary visa before you can be assessed for the permanent visa, and the Department will not consider a priority-processing request before you are eligible for that assessment.

When you are eligible, the FAQ describes submitting documents this way: log in to ImmiAccount, select "New application" and then "Family", select "Stage 2 - Permanent Partner Visa Assessment (100, 801)", and complete the online form using your application ID. You can find that ID in the Department's correspondence, including your acknowledgement of application received letter or your notification of visa grant letter.

What if I cannot upload something in time, or cannot see the application at all?

Two different problems have two different tools. If you cannot provide documents within the specified timeframe, the FAQ says you can request additional time using the Partner processing enquiry form; your request must include evidence of the steps you took, such as a payment receipt or booking confirmation, and must be made before the original response timeframe expires. The Department cannot guarantee additional time will be given.

If the issue is technical — for example, a Partner visa application you cannot import into your ImmiAccount — the FAQ directs you to the ImmiAccount Technical Support Form, selecting "Enquiry/Issue – Unable to import application". Not all visa applications can be imported.

Frequently Asked Questions

Can I add my child after I have already lodged my Partner visa application?

Yes. The Department's Partner visa FAQ directs you to the step-by-step tab of your visa's web page, then "after you apply", then "add family members". The child is added to the existing application, so your application ID does not change.

Which subclass page do I use — 820, 801, 309, 100 or 300?

Use the page for the subclass you applied for. The Department repeats the same "after you apply → add family members" path for subclass 820, 801, 309, 100 and the Prospective Marriage visa (subclass 300).

Do I need a separate application for my child if I already hold a 309 or 820?

The Department describes a separate route in that case: your child can apply for a Dependent child visa (subclass 445). Once your child holds that visa, follow the "When you have this visa" instructions on the subclass 445 page to add them to your Partner application.

Where do I upload the documents for my child?

Attach them to your application in ImmiAccount, following the Department's "Attach documents to your application" instructions. Health examinations can be completed after you apply, and the results remain valid for 12 months.

Will adding a child speed up or slow down my Partner visa?

The Department does not state that adding a child changes your processing priority. Priority is set under Ministerial Direction 117, with onshore subclass 820 and 801 applications given highest priority and offshore subclass 300, 309 and 100 applications given lower priority.

Can I still be asked for documents again after I upload them?

Yes. The Department may ask you to provide documents again if they expire before it decides your visa, and health assessment results are valid for 12 months. A health undertaking, if requested, is valid for 6 months.
