Did you get this information from the Mariners in Australian Waters site? If you look at the scans page of the documents (click on the red Scan for first, red 2 for the second) you will see the Medway sailed from Adelaide carrying copper, and that the Scott family were the only steerage passengers. They didn't seem to be too fussy about keeping records of inter-port passengers. You might have to look in SA for immigration records. Cheers Barbara
Thanks Barbara, State records NSW, there were 14 other passengers, but they were Cabin passengers. Will have a look at Mariners page and check Adelaide, regards Kerry
