Evidence required
Evidence of child migrant status
You will need to produce evidence of your former child migrant status with your application for Australian citizenship. You can get this through the Child Migrants Trust. This service is free.
See: The Child Migrants Trust
Evidence of citizenship
If you are an Australian citizen but do not have a certificate to prove it (for example, they were not normally issued to children under the age of 16), you can apply for evidence of Australian Citizenship (form 119).

Evidence of residence
If you do not have a passport or other official documents to prove you are or have been living permanently in Australia, and need such evidence, for example, to demonstrate eligibility for government benefits, you can get a Certificate of evidence of residence status (form 164). While there is normally a fee for this, it is waived for former child migrants (unaccompanied). Evidence is required from the Child Migrants Trust.
