HI

"then the Australian Navy" - WW2 Australian Navy records are online at NAA.gov.au but are only a couple of pages.
FWR gets some of their records from NA UK and a lot from free sites like CWGC, but all are transcribed, so you don't see the actual document. They do have some of their own records, but any for WW2 will be able to be found free elsewhere or on Ancestry etc. Read their blurb on what they have.
regards
Robert
