Any immigrant arriving in Sydney who might have had an infectious disease was quarantined here until they were cleared. We read that most people considered this a 'holiday' as they were looked after, fed, entertained and even had a beach for swimming.
Back in those days, there were the different classes on ships and so the Station was set up with the different precincts, first, second and third class precincts. The first class passengers had a nice dining room with lovely crockery but the poor old third class passengers had a much different experience.
A walk down to the wharf to view the relics wouldn't be complete without a visit to the toilets, no guessing here as to which one to go in!
