Yes, Australia allows dual and multiple citizenship. You can be an Australian citizen while also holding another nationality, provided the laws affecting your other citizenship allow you to retain it.
For migrants with family, property or longstanding connections overseas, the practical questions go further. Will becoming Australian affect your original citizenship? Which passport should you use? Can your children hold both nationalities? And does an Overseas Citizen of India card count as Indian citizenship?
This guide explains the Australian position and the checks to make before applying or travelling. The rules of each country matter, so a decision that works for one family may have different consequences for another.
What does dual citizenship mean?
Dual citizenship means a person is legally a citizen of two countries. Multiple citizenship describes citizenship of more than one country, including three or more.
Citizenship is different from owning a passport. A passport provides evidence of nationality and supports international travel; it does not necessarily tell the whole story of how citizenship was acquired or retained.
Permanent residency is also different. Holding an Australian permanent visa while remaining a citizen of another country does not make you an Australian dual citizen.
The Department of Home Affairs confirms that Australian citizens may also hold the citizenship of another country or countries if the laws of those countries allow, known as dual or multiple citizenship, while advising applicants to check the laws of their other countries of citizenship.
Does Australia require you to give up your original citizenship?
Australia does not generally require citizenship applicants to renounce their existing nationality. However, Australian law cannot preserve a nationality that another country withdraws when you acquire foreign citizenship.
Before applying, ask the relevant foreign authority:
- Will acquiring Australian citizenship affect my current citizenship?
- Does the answer depend on whether citizenship was acquired by birth, descent or naturalisation?
- Is permission, registration or notification required?
- Are there separate rules for children?
- What happens to my existing passport?
Obtain an answer that addresses your circumstances. A general statement that a country “allows dual citizenship” may leave out conditions that matter to you.
Which countries allow dual citizenship with Australia?
There is no Australian application that approves a particular pairing of nationalities. You must satisfy the relevant rules of each country.
The following examples illustrate why individual checking matters:
| Country | General position | Practical consideration |
|---|---|---|
| United Kingdom | British citizenship can be held alongside another citizenship. | British dual citizens must check the documents accepted for travel to the UK. |
| New Zealand | New Zealand permits dual and multiple citizenship. | Separate citizenship and passport requirements still apply. |
| India | Indian law does not generally permit dual citizenship. | OCI status is a separate arrangement and does not preserve Indian citizenship after naturalising as an adult elsewhere. |
The UK Government's dual citizenship guidance and New Zealand Government's guidance confirm their positions. India's authorities explain its different approach in their citizenship and passport surrender guidance.
This table is illustrative. It does not determine eligibility to acquire any of these citizenships or cover every nationality.
Can you hold Indian and Australian citizenship together?
For an adult Indian citizen voluntarily becoming Australian, the general answer is no. India's citizenship rules do not generally permit retaining Indian citizenship after acquiring another nationality.
Plan the transition before your citizenship ceremony and any overseas travel. Check the applicable passport surrender requirements with the Indian mission responsible for your Australian location. Do not assume an Indian passport remains available for use simply because its printed expiry date has not passed.
Children's circumstances can involve different provisions. Obtain specific guidance before applying for citizenship or a foreign passport for a child.
Is OCI the same as dual citizenship?
No. Despite its name, Overseas Citizen of India (OCI) status is not Indian citizenship.
India's Ministry of External Affairs expressly distinguishes OCI from dual citizenship. OCI provides specified immigration and other benefits to eligible foreign nationals, but does not confer the political rights of an Indian citizen, including voting rights.
An Australian citizen with OCI therefore holds Australian citizenship and OCI status, rather than Australian and Indian citizenship solely because of the OCI card.
Eligibility, exclusions and documentation must be checked separately. The official OCI portal lists evidence such as current nationality documents, proof of qualifying Indian origin or relationship, and applicable Indian passport surrender evidence.
How do you apply for dual citizenship in Australia?
There is no separate Australian application simply called a “dual citizenship application”. You apply through the Australian citizenship pathway relevant to you, while separately checking whether you retain your other nationality.
For many migrants, the pathway is citizenship by conferral. The general residence requirement commonly involves:
- Four years of lawful residence immediately before applying.
- The final 12 months as a permanent resident for citizenship purposes.
- Absences within the permitted limits: generally no more than 12 months in the four-year period and 90 days in the final year.
Special arrangements, exemptions and discretions can apply. New Zealand Special Category visa holders should check the citizenship-specific treatment of their status. Use the Home Affairs residence guidance, rather than relying only on a calendar anniversary.
Residence is only part of eligibility. Identity, character and other requirements also apply. Our Australian citizenship application guide explains the broader pathway.
When do you actually become Australian?
For most conferral applicants, approval is followed by a ceremony where they make the citizenship pledge. Approval alone does not complete that process for applicants required to make the pledge.
Check your decision letter and the official ceremony guidance. The acquisition date matters when assessing the effect on another nationality and planning passport applications.
Can children have dual citizenship?
Yes, depending on the laws applying to them. A child's position should be checked independently of the parents' passports.
Children born in Australia
Under the current general rule, a child born in Australia acquires Australian citizenship at birth if at least one parent is an Australian citizen or permanent resident at that time, subject to statutory exceptions.
Birth in Australia alone does not make every newborn Australian. There is also a separate rule for children ordinarily resident here throughout their first 10 years, with details requiring assessment under the Australian Citizenship Act 2007.
Whether the child also acquires another citizenship depends on that country's law.
Children born overseas
A child born overseas to a parent who was Australian at the time of birth may qualify for citizenship by descent. An application and approval are required; it should not be treated as automatic.
Additional requirements can apply where the parent also acquired citizenship by descent. Check the Home Affairs descent pathway before arranging the child's Australian passport or travel.
Which passport should a dual citizen use?
Australian Government guidance is to use your Australian passport when entering and leaving Australia. Travelling to Australia only on a foreign passport can create airline boarding or border-processing difficulties.
For your other country of nationality, check its entry and exit rules. It may require you to use its passport. Carry the documents needed for the full journey, including transit points.
Read Smartraveller's dual-national travel advice before booking. Tell the airline if different passports will be needed to establish entry rights at different destinations.
A practical point for British–Australian citizens
The UK’s own guidance is direct on this: British dual citizens should travel with a valid British or Irish passport, or the relevant certificate of entitlement, and cannot get an Electronic Travel Authorisation (ETA) at all — a foreign passport does not create an alternative pathway into the UK for them.
Specific alternative arrangements exist in limited circumstances, including carrier discretion for some expired-passport cases. Check the current UK travel instructions instead of relying on documents accepted on a previous trip.
What responsibilities and limitations should you understand?
Dual citizenship can support family connections and access to rights in two countries. It also means you need to understand obligations arising under both systems.
Voting and electoral enrolment
Eligible Australian citizens must enrol and vote. Holding another citizenship does not remove that obligation. Check your details after becoming Australian using the Australian Electoral Commission's enrolment guidance. Separate arrangements apply if you move overseas.
Assistance overseas
Australian consular assistance may be limited in your other country of nationality if its authorities treat you solely as their citizen. Australian officials cannot override local laws or guarantee access to someone detained there.
The Consular Services Charter explains the assistance available and its limits.
Local obligations
Some countries impose military service or other obligations on their nationals, including those living overseas. Ask the relevant authority about your position before travelling. Using a different passport does not necessarily remove an obligation connected to nationality.
A checklist before you apply or travel
Create a short record for each family member, rather than assuming one answer covers everyone:
- Current status: List each citizenship, how it was acquired and any uncertainty about retention.
- Evidence: Gather birth certificates, citizenship certificates, passports and name-change records.
- Foreign-law confirmation: Record the authority contacted, its advice and any deadlines or conditions.
- Australian pathway: Identify whether the person needs conferral, descent, evidence of citizenship or another assessment.
- Travel documents: Check passport validity, matching personal details and destination entry requirements.
- Timing: Allow for citizenship decisions, ceremonies, passport issuance and any surrender or OCI process.
For a consultation, explain what you want to achieve: applying for citizenship, moving overseas, visiting family or documenting a child's status. That helps identify which questions need Australian migration advice and which require the other country's authority.
Frequently asked questions
Does Australia allow triple citizenship?
Australia permits multiple citizenship, so holding three nationalities can be possible. You must also meet the acquisition and retention rules applying to each other nationality.
Do I need two valid passports to remain a dual citizen?
Passport validity and citizenship are different matters. An expired passport does not, by itself, establish loss of citizenship. However, you need acceptable current documents for travel and should confirm any separate nationality obligations.
Does Australian permanent residence count as citizenship?
No. Permanent residence is an immigration status. Becoming an Australian citizen generally requires a separate qualifying pathway; a permanent visa does not itself create dual citizenship.
Can I keep my British citizenship when becoming Australian?
Generally, yes. Both countries permit dual citizenship. Check your individual status and travel documents, particularly the UK's current requirements for British dual citizens entering the country.
Does an OCI card let me vote in India?
No. OCI does not confer Indian citizenship or voting rights. It is a separate status available to eligible foreign nationals under Indian law.
Is my overseas-born child automatically Australian?
Not merely because one parent is Australian. Citizenship by descent generally requires an application and approval, with eligibility depending on the parent's status at birth and other applicable requirements.
Does marrying an Australian automatically give me citizenship?
No. Marriage alone does not grant Australian citizenship. Your visa and citizenship pathways still need to be assessed against the relevant requirements.
What if I became a foreign citizen before April 2002?
Historical rules may have caused loss of Australian citizenship in circumstances that no longer produce that result. Check Home Affairs' resumption guidance; do not assume an old Australian document confirms your current status.
Can I use my foreign passport after my citizenship ceremony?
Only if you remain entitled to use it under that country's laws. For travel into and out of Australia, follow the Australian Government's advice to use your Australian passport.
Can Nanak Migration confirm another country's citizenship law?
Nanak Migration can assess the Australian citizenship pathway and identify questions affecting your plans. Obtain authoritative confirmation of foreign nationality rules from the relevant embassy, consulate or appropriately qualified foreign-law adviser.
Plan your citizenship application with Nanak Migration
Citizenship decisions affect more than an application form. Your residence history, family circumstances and future travel should be considered together.
Book a consultation with Nanak Migration to discuss your Australian citizenship eligibility and the documents needed for your circumstances.
