Australia In a Nutshell
The Great Barrier Reef and the Coral Sea offer tremendous volume and diversity of marine life, well managed marine parks, professional dive operations and diving suitable for all experience levels. There is great diving at every depth and a variety of marine life including sharks, minke whales and large potato cod (potato grouper).
Marine Life / Diving Conditions
Australia doesn't hold the best macro opportunities. It is better known for its "big stuff" like sharks and whales, and some great wreck dives. Best time to dive fluctuates for what area of Australia you are diving. Numerous areas are accessable year round, but the south parts can have bad weather between May - Oct. Although you can take day trips out to dive - in general, the further you go the better the diving becomes. Due to this, liveaboards are typically better to properly experience what all Australia diving has to offer. In gerneral, the Great Barrier Reef is the most popular, but the Coral Sea is better. Water temperatures can be anywhere between 70 - 87 degrees. Visibility on day trips will be between 50 and 100 ft. while further sites reached via liveaboard can be up to 150 ft. Majority of divesites will be relatively shallow, 30 - 60 feet.
Due to Australia's size, it is near impossible to cover all the things you can do while visiting Australia. It is also dependent on what areas you are visiting. But to touch on a few; no trip can be complete without learning of Australia's Aboriginal culture, try taking a hike to the sacred site of Uluru to catch the sunrise or sunset. For you city lovers, climb the Sydney Harbor Bridge or see a show at the iconic Sydney Opera House. Or just take a drive along The Great Ocean Road - a scenic drive you won't forget.
