My grandfather was listed as fireman on the passenger listed when he emigrated from Rotterdam to Australia in 1914 for the second time. His imigration to Australia was complicated

The first time coming to Australia in 1910, he stowed away on a coalship.
Even though he was recorded as a fireman from Rotterdam on the 1914 passenger list and also on his naturalisation papers in 1912 - he worked on the shipping docks in Victoria, Australia as a rigger.
This was also the same for my father's side of the family when emigrating from England to Australia. They had a different occupation once in Australia to what was recorded on the passenger list.
