Can you become Australian at the same time as your child born in Australia while are permanent resident?

Yes, a permanent resident of Australia may become an Australian citizen when their child born in Australia is granted Australian citizenship. If the permanent resident parent meets all of the eligibility requirements for citizenship and has maintained a certain level of residency in Australia, they may apply for Australian citizenship through a pathway called "Citizenship by Descent."

To qualify for citizenship by descent, the permanent resident parent must satisfy the following conditions:

1. The parent must have been a permanent resident of Australia for at least one year immediately preceding the date of their application for citizenship.

2. The parent must have been physically present in Australia for a total of at least four years within the six years preceding the date of their application, including the year immediately preceding the application.

3. The parent must satisfy the English language proficiency requirement, which can be met through various means such as providing evidence of sufficient English skills, like passing an English language proficiency test.

4. The parent must demonstrate an adequate knowledge of Australia and its people, which can be demonstrated by passing a citizenship test covering basic knowledge about Australian civics, history, and values.

If the permanent resident parent fulfills all the above criteria and has no disqualifying factors, they can apply for Australian citizenship concurrently with their child born in Australia. Upon successful assessment of their application, they will be granted Australian citizenship simultaneously with the child's citizenship.

It is important to note that the requirements and processes for acquiring Australian citizenship may change from time to time. It is recommended to refer to the official sources and guidelines provided by the Department of Home Affairs or consult with an immigration lawyer for accurate and up-to-date advice regarding your specific circumstances.
