If you previously applied for grant of Australian citizenship and were unsuccessful solely on the basis of not meeting the residence requirements, you do not have to again pay the amount previously paid if you reapply within three (3) months of becoming residentially qualified. 

Former British child migrants who came to Australia between 22 September 1947 and 31 December 1967 under the British Child Migration Scheme (BCMS) are not required to pay an application charge. 

Evidence of arrival and sponsorship under the BCMS will need to be lodged with your application and can be obtained from the Child Migrants' Trust in Melbourne or Perth. 

For further information refer to form 1014I Former British Child Migrants or telephone the Citizenship enquiry line on 131 880.
