Does Australia Allow Dual Citizenship?

Australia allows dual citizenship. Since April 2002, Australian law has permitted its citizens to hold citizenship of another country simultaneously. There is no requirement to renounce your original nationality when you become an Australian citizen — from Australia's side.

The catch is that Australia cannot control what other countries do. Whether you can actually hold both passports depends entirely on the laws of your birth country or previous country of citizenship. Some countries permit it freely. Others require you to formally renounce before you naturalise. A few will simply cancel your original citizenship automatically when you swear the Australian pledge, without you needing to do anything — or being able to stop it.

What Australia's Law Says

The Australian Citizenship Act 2007 contains no provision stripping Australian citizenship from someone who acquires a second nationality. When you become an Australian citizen by conferral, your citizenship certificate is yours to keep regardless of what happens to your other passport.

The only situation where an Australian can lose their citizenship is if the Minister revokes it on specific grounds — typically related to terrorism offences or conduct seriously prejudicial to Australia's national security. Holding a foreign passport is not one of those grounds.

So from an Australian legal perspective, dual citizenship is straightforward: you are welcome to hold it.

The Countries That Prohibit Dual Citizenship (And What Happens If You're From There)

The complexity falls on the other side. Here is how the most significant source countries for Australian citizens approach dual nationality:

India prohibits dual citizenship under the Indian Citizenship Act 1955. When you voluntarily acquire Australian citizenship, you automatically lose your Indian citizenship from the moment you make the pledge. You are required to surrender your Indian passport and obtain a "Surrender Certificate." India's alternative for Australian-Indian citizens is the Overseas Citizen of India (OCI) card — a lifelong, multi-entry visa that provides many (but not all) rights of residency and travel to India. OCI holders cannot vote in Indian elections or own agricultural land.

China similarly does not permit dual citizenship. Article 9 of the PRC Nationality Law states that any Chinese national who settles abroad and is naturalised as a foreign citizen automatically loses Chinese citizenship. This happens by operation of law — you do not need to take any separate step, and you cannot prevent it by declining to register the change with Chinese authorities. If you enter China on a Chinese passport after becoming an Australian citizen, the Chinese government will treat you as a Chinese citizen and Australian consular protection will not be available to you.

Malaysia cancels citizenship under Article 24 of its Constitution upon naturalisation elsewhere. Malaysian-born people becoming Australian citizens must formally renounce via "Form K" and return their Malaysian IC and passport.

Singapore requires adults to renounce Singaporean citizenship before or upon naturalisation elsewhere. Note that Singaporean males with outstanding National Service obligations may find renunciation delayed or complicated.

Countries That Allow Dual Citizenship With Australia

Many of Australia's largest migrant communities come from countries with more accommodating rules:

United Kingdom: Permits dual citizenship freely. UK nationals becoming Australian citizens face no complications on the UK side.

Philippines: Under Republic Act 9225, natural-born Filipinos who become citizens of another country can re-acquire or retain Philippine citizenship by taking a new Philippine Oath of Allegiance. This can be done through the Philippine Embassy in Canberra or the Consulate General in Sydney or Melbourne. Re-acquisition restores the right to own land in the Philippines and to vote in Philippine elections through overseas voter registration.

Vietnam: Until 2025, Vietnam took a case-by-case approach requiring proof of meritorious contributions or special circumstances for a Vietnamese national to retain their citizenship upon naturalisation abroad. From 1 July 2025, Law No. 79/2025/QH15 significantly liberalised this position, permitting overseas Vietnamese to retain Vietnamese nationality as long as doing so does not harm Vietnam's national interests. Vietnamese-Australians who previously lost their nationality may also be able to restore it under this new framework.

South Africa: Permits dual citizenship, though it requires prior permission from the Minister of Home Affairs before naturalising in another country. Failure to get this permission technically results in forfeiture of South African citizenship, but this is rarely enforced in practice. It is worth formalising if you plan to use your South African passport.

New Zealand: Permits dual citizenship. New Zealand citizens on Special Category Visas have a unique direct pathway to Australian citizenship that does not require obtaining a separate permanent resident visa first — a change that came into effect in July 2023.

What You Should Do Before Your Ceremony

If your birth country prohibits dual citizenship, you need to understand the sequence of events and any steps you are required to take. In most cases:

1. You become an Australian citizen at the ceremony when you make the pledge
2. Your original citizenship is lost at that point (either automatically or through formal renunciation)
3. You then apply for whatever alternative status is available — OCI for Indian nationals, re-acquisition under RA 9225 for Filipinos, and so on

For Indian nationals, this means acting quickly after the ceremony: surrendering your Indian passport, applying for the Surrender Certificate, and then lodging your OCI application. The OCI process through VFS Global typically takes six to seven weeks.

For Chinese nationals, the practical concern is making sure you have Australian travel documents sorted before any planned travel to China, as you will no longer be able to travel on a Chinese passport.

The Australia Citizenship Guide includes a country-by-country breakdown for the six most common nationality situations — covering the exact steps, forms, fees, and timelines for each. If dual citizenship implications are your primary concern, that section alone saves several hours of research across consular websites that are often outdated or incomplete.

The Practical Upside

For most people coming from countries that allow dual citizenship, the question of "does Australia allow it?" is the easy part. The harder question is whether to apply for Australian citizenship at all, given what it might cost in terms of your original nationality.

For those from countries like India or China, the decision is genuinely consequential — particularly around property rights, family inheritance, and access to social services in the home country. It is worth thinking through carefully rather than treating it as a paperwork formality.

For those from the UK, New Zealand, the Philippines, Vietnam (from mid-2025), or South Africa, holding both passports is either straightforward or achievable with modest additional steps — and the benefits of an Australian passport (visa-free access to over 180 countries, the security of irrevocable residency) are significant.
