Hi Sue

Go to the http://mariners.records.nsw.gov.au/ site. On that page you will see "If you know the Vessel name you are seeking but not the date - try the Index to Vessels Arrived into Sydney from 1837 to 1925, before returning here to check for crew and passengers."
Click on the link to the index, put in Suevic as ship and 1901 as date.
Unfortunately they have yet to transcribe the passenger list but I have asked them re any explanation as to obvious discrepancy
