Maritime Journey from Britain to Australia, 1788-1960
As maritime technology improved, mostly through better ship design and improved navigation, long distance maritime journeys were reduced substantially. For instance, initial journeys in the late 18th and early 19th centuries between Britain and Australia took between 70 and 110 days. The use of steam engines and the Suez shortcut in the late 19th and early 20th centuries reduced the journey to about 40 days. In the 1950s, the last liners, prior to the dominance of air transportation, were able to do so in about 25 days.
