Which air conditioning is best? Evaporative, split system or ducted?
In order to achieve comfortable cooling and dehumidification, the air conditioning system must be correctly sized. Traditionally, central air conditioning units have been sized in tons, with one ton cooling 12,000 BTUs per hour. As a general rule of thumb, you need 12,000 BTUs or 1 Ton of cooling for each 500 square feet of living space. This ratio assumes that the space you are cooling has standard 8 foot ceilings, that windows make up less than twenty percent of southern facing walls, that your windows have drapes or blinds and that you close them during the heat of the day, and that your walls and attic are insulated. In the past, you could divide the square footage of your living space by 500 to determine the number of tons you need. However, manufacturers have re-engineered their equipment and most new 13 SEER equipment now cools fewer than 12,000 BTUs per advertised ton. Consequently, if you need to replace your existing equipment, you may have to buy a larger unit (more tons) than your present unit, in order to get the same amount of cooling. To insure that you purchase the right equipment, you will need an experienced air conditioning technician to visit your residence or business, run a heat load, and identify the size and model of equipment which will best meet your needs.

depending on your budget either go ducted or split system. the only difference is a split system only does a good job on one or two rooms where as a ducted system will cool or heat your whole house. In any coastal parts of Australia evaporative coolers are almost totally useless, they are only any use with places that have very low humidity.
