For South Australia's first settlers the average travel time by sailing ship was about 100 days. In the 1850's and 1860's clippers using the great circle route cut the time to
about 75 days. From the 1880's steamships traveling through the Suez Canal had reduced the time to 45 days. Later, ocean liners could make the
journey in 30 days. By the 1960's aircraft had reduced travel time to one day.
