Australia has effectively signed open borders with India:

The Australia-India Migration and Mobility Partnership Agreement (MMPA) includes the following provisions:

1. Five year student visas, with no caps on the numbers of Indians that can study in Australia.

2. From 1 July this year, Indian graduates of Australian tertiary institutions on a student visa can apply to work without visa sponsorship for up to eight years.

3. The Mobility Arrangement for Talented Early Professionals Scheme allows 3000 of India’s top graduates and early career professionals to work and stay in Australia for up to two years. They can apply for a permanent skilled visa, and spouses will have unlimited work rights.

4. Three-month visitor visas available to Indians for family or business purposes (no caps on numbers).

Not only that:

5. Australia must also recognise Indian vocational and university degrees as being comparable to Australian qualifications for study and employment purposes
