What this form asks for

The AI fills all of it, from your answers or your documents.

Form 866 is the Australian Department of Home Affairs application used by eligible people in Australia to request a Protection visa (subclass 866). It collects detailed information about the main applicant and included family members (identity, citizenship, residence history, relationships, documents, travel, employment/education, and character/health), as well as the applicant’s protection claims and supporting details. Accurate completion is important because the information is used to assess eligibility, identity, security/character requirements, and the basis of the protection claim. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

16 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Validates total number of people included is a positive integer and matches provided person sections

Checks that 'Number of people included in this application' is a whole number greater than or equal to 1 (must include the main applicant). It also verifies that the count aligns with the number of populated person records (e.g., Other person 1/2 and additional member blocks like m.* 3-6, dependants, newborns) and that no extra person blocks are filled beyond the declared total. This prevents missing applicants/dependants or accidental inclusion of unintended people. If the validation fails, the submission should be blocked and the user prompted to correct the count or complete/remove person entries.

Ensures main applicant name fields are complete and contain only valid characters

Validates that the main applicant 'Family name' and 'Given names' are not blank, are within reasonable length limits, and do not contain invalid characters (e.g., digits-only, control characters, or excessive punctuation). Names should allow common legal-name characters such as letters, spaces, hyphens, and apostrophes. This is important for identity matching against passports/birth certificates and downstream record creation. If invalid, the form should require correction before acceptance.

Enforces single selection for sex fields per person (mutual exclusivity)

Checks that exactly one sex option is selected for each person (Male/Female/Indeterminate-Intersex-Unspecified) and that multiple boxes are not checked simultaneously. It also flags cases where none are selected when the person record is otherwise populated. This ensures consistent demographic data and avoids contradictory entries. If the validation fails, the user must select one option or correct conflicting selections.

Validates date of birth format and plausibility for all persons

Ensures each date of birth is a valid calendar date in the expected format and is not in the future. It also applies plausibility bounds (e.g., not older than a configured maximum such as 120 years) and requires DOB when a person’s name is provided. This reduces data entry errors and supports eligibility/identity checks. If invalid, the system should reject the submission or require correction for the affected person.

Validates birthplace fields completeness and country normalization

Checks that place of birth town/city and country are provided for the main applicant and any other person records that are included, and that country values come from an approved list (or are normalized to standard country names/codes). It also flags placeholder values like 'Select' or empty strings. Accurate birthplace data is critical for identity verification and jurisdictional processing. If validation fails, the user must provide valid town/city and a recognized country.

Validates citizenship field presence and handles stateless rule

Ensures citizenship/nationality is provided for each included person and is not a placeholder (e.g., 'Select'). If the applicant indicates statelessness (by entering 'stateless' or equivalent), the system must require the previous country of citizenship as instructed. This is important for legal status assessment and document checks. If the rule fails, the submission should be blocked until citizenship information is corrected or completed.

And 10 more checks
  • Validates current country of residence and arrival date consistency
  • Validates immigration/status code field is present and conforms to allowed pattern
  • Enforces relationship status selection rules and prevents contradictory statuses
  • Requires relationship event details when applicable (date/place/previous name)
  • Validates multiple current partners branching and required details
  • Validates 'other current relationship' branching for engaged/never-married scenarios
  • Validates biological relationship Yes/No exclusivity and dependent explanation fields
  • Validates contact information formats (phone numbers and email) and conditional requirements
  • Validates document entries when document presence is marked 'Yes' (type/number/country/issue/expiry)
  • Validates required declarations/consents checkboxes are all affirmed

Common Mistakes in Completing Form 866 (Protection visa)

The ones the AI is built to catch.

Incorrect total number of people included in the application
Applicants often enter only the number of dependants (or only themselves) instead of the total number of people included, which must include the main applicant plus all dependants. This creates mismatches with the “Other person” and dependant sections and can trigger follow-up requests or delays. Recount everyone who will be assessed under the application and ensure the number aligns with the number of additional person blocks you complete. AI-powered tools like Instafill.ai can cross-check the declared total against the number of person sections filled and flag inconsistencies before submission.
Name fields not matching identity documents (order, spelling, or missing middle names)
A very common error is entering nicknames, shortened given names, omitting middle names, or swapping family and given names—especially for applicants from cultures with different naming conventions. This can cause identity verification issues and inconsistencies with passports, birth certificates, and prior visa records, leading to processing delays. Enter names exactly as shown on official documents, including all given and middle names in full, and keep the same spelling/diacritics where possible. Instafill.ai can help by extracting names from uploaded documents and formatting them consistently across all repeated name fields.
Selecting multiple or no options for sex
Because sex is presented as three separate checkboxes (Male/Female/Indeterminate/Intersex/Unspecified), people sometimes tick more than one or forget to tick any. This can make the form internally invalid or require manual clarification by the case officer. Choose exactly one option that matches the person’s identity documents or preference where allowed, and repeat consistently for each “Other person” section. Instafill.ai can validate single-choice checkbox groups and prevent multiple selections.
Date format errors and inconsistent timelines (DOB, arrival dates, relationship dates)
Applicants frequently mix date formats (DD/MM/YYYY vs MM/DD/YYYY), enter partial dates, or create impossible sequences (e.g., arrival date before date of birth, relationship event date after separation/divorce). These inconsistencies can undermine credibility and trigger requests for clarification or supporting evidence. Use one consistent date format as required by the form and sanity-check that all timelines make sense across residence, travel, relationships, and employment. Instafill.ai can standardize date formats and run logic checks to catch timeline conflicts.
Confusing place of birth town/city vs country fields
People often put the country in the town/city field, use a province/state instead of a city, or use informal abbreviations that don’t match official records. This can cause mismatches with identity documents and complicate background checks. Enter the specific town/city in the town/city field and the country name in the country field, using the same wording as the passport/birth certificate where possible. Instafill.ai can auto-suggest standardized country names and keep location fields correctly separated.
Citizenship/nationality entered incorrectly (especially dual citizenship or stateless cases)
A common mistake is listing ethnicity, place of birth, or “resident” status instead of citizenship, or listing only one citizenship when the person holds multiple. For stateless applicants, people often leave the field blank instead of providing the previous country of citizenship as instructed. Incorrect citizenship details can lead to additional screening, document requests, or delays. List all current citizenships/nationalities exactly, and if stateless, follow the instruction to provide the previous country of citizenship; Instafill.ai can prompt for missing required details based on the stateless/dual-citizen scenario.
Leaving placeholder dropdowns as 'Select' or not providing required codes
This form includes multiple fields that appear as dropdown placeholders (e.g., 'Select') and a “Status in this country (code)” field that expects a short code like C or PR. Applicants often leave 'Select' unchanged or type a long explanation instead of the requested code, which can make the form incomplete or inconsistent with the form’s expected values. Always choose an actual option from dropdowns and use the exact code/short text requested for status, adding details only where a narrative field exists. Instafill.ai can detect unmodified 'Select' placeholders and validate that status fields match expected code formats.
Relationship status misunderstandings and multiple boxes checked
Because relationship status is presented as many checkboxes (married legally, married by tradition, religiously, engaged, de facto, separated, divorced, widowed, never married), applicants sometimes tick several that conflict (e.g., divorced and married) or tick “never married” while also providing marriage details. This can create credibility issues and force the assessor to request clarification. Select the single current status that best describes the legal/current situation, and only add additional context in the appropriate detail fields if the form allows. Instafill.ai can flag mutually exclusive selections and guide you to the correct combination.
Not completing conditional fields when required (or completing them when not allowed)
Several fields are conditional—e.g., relationship event date/place/previous name should be filled only when the status is not “Never married,” and additional partner details should be filled only if “Yes” to having more than one partner. Applicants often skip required conditional details (causing incomplete sections) or fill them despite selecting “No,” creating contradictions. Review each Yes/No and status selection and ensure the corresponding detail fields are completed only when triggered. Instafill.ai can enforce conditional logic so the right fields appear, are required, and are consistent with your selections.
Inconsistent 'Other person' details across repeated sections (Person 1/2/3+)
When the form repeats similar blocks for multiple people, applicants commonly copy/paste and forget to update a date of birth, citizenship, or relationship-to-applicant field, or they mix up which person is “Other person 1” vs “Other person 2.” This leads to internal inconsistencies and can cause serious processing delays if identities appear duplicated or mismatched. Fill one person at a time, double-check each block’s name/DOB/citizenship, and ensure the relationship to the main applicant is correct for each individual. Instafill.ai can reuse verified data safely while preventing accidental carryover errors between person blocks.
Biological relationship section completed incorrectly (Yes/No mismatch and missing explanation)
Applicants often tick both “biologically related: Yes” and “No,” or they select “No” but leave the explanation blank, or select “Yes” but don’t describe the precise biological relationship. This can create ambiguity about family composition and eligibility considerations. Choose only one (Yes or No) and then complete the corresponding required text field: explain the non-biological connection or specify the exact biological relationship (e.g., biological mother, half-sibling). Instafill.ai can ensure only the correct follow-up field is completed and that it’s not left empty when required.

What is this form for?
This form collects detailed personal, family, identity, travel, and background information for the main applicant and any people included in the application. It’s used to assess eligibility and verify identity, relationships, and history.
Who should be included in “Number of people included in this application”?
Enter the total number of people covered by this application, including you (the main applicant) and any dependants or family members included. Count every person whose details you will provide in the form.
How should I enter my name (family name and given names)?
Enter your family name (surname) and all given/middle names exactly as shown on your identity documents (such as a passport or birth certificate). Avoid nicknames, abbreviations, or different spellings.
What if my sex is not male or female, or I prefer not to specify?
Select “Indeterminate / Intersex / Unspecified” if that best matches your situation or preference. Choose only one option that reflects how you want your record to be captured.
What does “Current country of residence” and “Date you arrived in this country” mean?
Your current country of residence is where you are living now. The arrival date is the date you first arrived in that country to live (not a short visit), unless the form instructions for your program specify otherwise.
What should I put for “Status in this country (code)”?
Enter the code or short description that matches your legal status in your current country of residence (for example, C = Citizen, PR = Permanent Resident). If you’re unsure, use the wording from your visa/residence permit or official documentation.
Which relationship status box should I tick if I have more than one type of marriage (civil and religious/traditional)?
Tick the option(s) that accurately reflect how your relationship is formally recognized (legal/civil, traditional/custom, and/or religious). If multiple apply, select all that are true and ensure the event date/place details match your current status.
Do I need to fill in “Date relationship status occurred” and “Place relationship status occurred” if I’ve never married?
No—those event details are only required when your relationship status is something other than “Never married or been in a de facto relationship.” If you select “Never married…,” leave the event date/place fields blank.
What does “Do you currently have more than one partner?” mean, and what happens if I answer “Yes”?
It asks whether you currently have another partner besides any partner included in this application. If you answer “Yes,” you must provide details of the additional current partner (name, DOB, relationship nature and duration, and other identifying information).
How do I complete the “Other person” sections (Other person 1, Other person 2, etc.)?
For each listed person, enter their name, sex, date/place of birth, citizenship, and relationship status as shown on their official documents. Then specify their relationship to the main applicant and whether they are biologically related, providing an explanation or precise biological relationship as requested.
What if someone is not biologically related to the main applicant—what should I write in the explanation?
Briefly describe the connection (for example, spouse, step-child, adopted child, cousin by marriage, guardian, or family friend) and any context that clarifies the relationship. Keep it factual and consistent with any supporting documents you may provide.
What documents or details should I have ready before starting this form?
Have passports/birth certificates, citizenship/nationality details, current residence and arrival dates, contact information, relationship history (dates/places), and any prior visa/application details available. You may also need UNHCR registration/mandate information, travel history, employment/education history, and any relevant legal/health background details if applicable.
