India has the largest diaspora population in the world , and many live in Australia . Non resident Indians ( NRI ) and Persons of Indian Origin ( PIO ) maintain strong cultural and economic links with India . However , the Constitution of India does not allow dual citizenship , so for many expatriates taking up residency , and eventually citizenship in Australian , this has led to loss of privileges in India , such as residency rights . India is one of the few remaining countries that prevent dual citizenship , and there have been attempts to resolve this , through Long Term Visas and more recently a pseudo citizenship Overseas Citizenship of India ( OCI ) has been created that has been taken up positively , with many Australians OCIs , cricketer Shaun Tait being a famous example , who are able to take residency in India without applying for a visa . However privileges of OCI holders depends on the Government policy of the day , and there have been instances where they have been denied additional rights afforded to full Indian citizens , such as during the 2016 Indian banknote demonetisation where non-citizens , including OCIs were denied rights to bring rupee notes back into the country
