Adding a family member or correcting an answer after lodging subclass 173 in 2026: Forms 1436 and 1023

If you have lodged a Contributory Parent (Temporary) visa (subclass 173) application and now need to add a family member or correct something you already told the Department, the two jobs use different forms: adding a person is done with Form 1436 (Adding an additional applicant after lodgement), while notifying an incorrect answer is done with Form 1023 (Notification of incorrect answers). According to the Australian Department of Home Affairs' official Contributory Parent (Temporary) visa (Subclass 173) page, as of August 2026, Form 1436 can only be used before a decision is made and must be accompanied by evidence of your relationship and a copy of the family member's passport; Form 1023 should be completed as soon as you can. Both can be submitted through ImmiAccount once your paper application has been imported, or through the Parent visa processing centre form.

What is the difference between adding a family member and correcting an answer?

Adding a family member changes who is included in the application — it is a request to bring another person into the subclass 173 case before a decision. Correcting an answer does not add anyone; it tells the Department that information already given on the application was wrong or incomplete. The first is a request for someone to join the case, and the second is a correction notice about what you have already said.

Because they do different things, they use different forms and different evidence:

	Form 1436 — adding a family member	Form 1023 — correcting an answer
Form name	Adding an additional applicant after lodgement	Notification of incorrect answers
What it does	Asks to include another person in the application	Tells the Department an answer already given was incorrect
When it can be used	Before a decision is made on the application	As soon as you become aware of the mistake
What else is needed	Evidence of the relationship, plus a copy of the family member's passport	The completed notification form
How to send it	ImmiAccount or the Parent visa processing centre form	ImmiAccount (once the application is imported) or the Parent visa processing centre form

Which form adds a family member after lodgement?

Use Form 1436 (Adding an additional applicant after lodgement). The official page states you might be able to add family members before a decision is made; it does not promise that every addition will be accepted. Along with the form, give evidence of your relationship and a copy of the family member's passport.

Subclass 173 is a paper-lodged visa — online lodgement is not available — so if the person was not in the original paper application, Form 1436 is the mechanism the page gives for bringing them in afterwards.

Which form corrects an incorrect answer?

Use Form 1023 (Notification of incorrect answers). The Department asks you to tell it as soon as you can if you made a mistake on the application, and Form 1023 is the notification form named on the official page. It is not a way to add a person or to change your mind about who should migrate.

If the mistake relates to identity or the accuracy of what you provided, speed matters: the page warns that there are consequences if you do not give accurate or complete information.

How do you submit Form 1436 or Form 1023?

How do you submit it through ImmiAccount after importing your paper application?

Although you cannot lodge subclass 173 online, you can import the paper application into ImmiAccount after you receive your acknowledgement letter. To import, log in to an existing ImmiAccount or create a new one, then enter your application ID, your date of birth, and your identity document number — an ImmiCard, passport or Titre de Voyage number. Both new and on-hand applications can be imported.

After importing, you can attach supporting documents, view messages, update your details and check status. This is also the route for uploading a completed Form 1023, and the page lists ImmiAccount as a channel for Form 1436 as well.

How do you submit it through the Parent visa processing centre form?

If you are not using ImmiAccount, the Parent visa processing centre form is the alternative channel the page gives for both Form 1436 and Form 1023. This matters for a paper-lodged visa because it means you are not forced to rely on the online account alone to get additions and corrections in front of the processing centre.

What supporting evidence does Form 1436 need?

Two things are named: evidence of your relationship to the family member, and a copy of that family member's passport. The page does not list a separate identity or character document set for the addition itself, so those two items are what the official step names.

Beyond that, the added person still has to satisfy the visa's own member-of-family rules. The page describes dependent children as those under 18; those aged 18 to 22 who are dependent on you or your partner; or those over 23 who cannot earn a living because of physical or cognitive limitations and are dependent on you or your partner. This article is general information drawn from the official page and is not personalised advice for your circumstances, so confirm current requirements against the Department's page or with professional advice before you act.

What else must you tell the Department after lodging?

Adding or correcting is separate from notifying other changes. The page says you must tell the Department about changes to your phone number, email, address, passport, relationship status, and family composition, including the birth of a child; you should also tell it if you want to withdraw the application.

A birth, for example, is a family-composition change you must report — but if you want the new child to be part of the subclass 173 application, the addition itself is made with Form 1436 before a decision, not by a change-of-details notice. Mistakes already written on the form go to Form 1023; new people go to Form 1436; other life changes are reported through the change-in-situation guidance the page points to.

Frequently Asked Questions

Can I add a family member to my subclass 173 application at any time?

Not at any time — the official page says you might be able to add family members before a decision is made on the application. The addition is requested with Form 1436, together with evidence of the relationship and a copy of the family member's passport. After a decision has been made, the page does not present Form 1436 as a way to add someone.

Which form do I use if I entered the wrong information on my subclass 173 application?

Use Form 1023, Notification of incorrect answers. The Department asks you to notify a mistake as soon as you can, and Form 1023 is the notification form named on the official page. You can upload it in ImmiAccount once your paper application has been imported, or send it using the Parent visa processing centre form.

Do I need to import my paper subclass 173 application into ImmiAccount to submit these forms?

Importing is required if you want to use ImmiAccount, because subclass 173 is paper-lodged and online lodgement is not available. After you receive your acknowledgement letter, you can import the application using your application ID, date of birth, and identity document number (ImmiCard, passport or Titre de Voyage number). If you would rather not use ImmiAccount, the Parent visa processing centre form is the alternative for both Form 1436 and Form 1023.

What documents does Form 1436 require?

The page requires evidence of your relationship to the family member and a copy of that family member's passport. It does not list a separate identity or character document set for the addition itself, so those two items are what the official step names. The added person must still meet the visa's member-of-family criteria.

Is telling the Department about a new baby the same as adding that child to the application?

No. A birth is a change in family composition that you must report, but reporting it is not the same as including the child as an applicant. To bring the child into the subclass 173 application before a decision, you complete Form 1436 with the required relationship evidence and passport copy.

Can I apply for subclass 173 online and manage everything online from the start?

No. The official page states that online lodgement is not available for temporary Contributory visa applicants and you must apply on paper using Form 47PA. Online management only becomes possible after lodgement, once you import the paper application into ImmiAccount.
