Australia is a year round diving destination although The Great Barrier Reef is at its best for liveaboard diving between August and December. It is worth noting that due to cooler temperatures, down to 73° F (23 °C) from 86° F (30° C), visibility is much better in June. Rowley Shoals on the other hand is at its best during September and October. The season for whales in Australia depends on the type of whale, from June to September humpback whales migrate to warmer waters near The Great Barrier Reef. From May to September dwarf minke whales can be seen migrating as well.
