Diving Australia in November
Coral spawning, turtle nesting begins, and stinger season returns to the tropics.
November brings the Great Barrier Reef's mass coral spawning, turtle nesting on the southern cays, and the start of stinger season in tropical waters.
Christmas Island's whale shark season begins, tied to the red crab spawning, and the east coast warms quickly.
Southern Australia is comfortable again, and it is a strong month for combining temperate and subtropical diving in one trip.
