The cruise port of Brisbane is the second most departed-from port in the South Pacific, departure point of only thirty cruises per year from Royal Caribbean to the South Pacific, as well as other places.
Cruises leaving from Brisbane during the peak seasons of winter and spring are a bit more expensive than the low seasons of spring and fall. Overall sailings from Brisbane are somewhat inexpensive compared to other ports. See the diagram below for the monthly average cost per day (Cruises only depart from Brisbane between January and December).
