Over the first few years of the 20th century, Form 21 (Certificate of Domicile, then Certificate Exempting from Dictation Test) went through various iterations as the procedures for administering the Immigration Restriction Act were bedded down. After 1906, the CEDT form remained basically the same until the Dictation Test was abolished in the late 1940s.
The certificates below are the first example of each iteration of the certificate found in the records of the NSW Collector of Customs in the National Archives in Sydney. Certificates of Domicile and CEDTs issued in Sydney are held in series ST84/1, except for those issued in 1902 which are held in SP11/6.

1903 – First Form 21 Certificate of Domicile
Certificates of Domicile from 1903 onwards are held in series ST84/1. More about this first certificate in an earlier post.
