We've been publishing the list of the world's top dives since 2000 and until last year the SS Yongala consistently topped the list. Now though, the Yongala has been forced into third position. She's still my favourite dive site though.
The dives are fairly evenly balanced between Northern and Southern hemispheres, the South winning by 6 entries to 4. It is also a 6:4 ratio in Reefs versus Wrecks.

The list is compiled from divers' votes - cast your vote here. We know it's difficult to choose your favourite dive sites, and we ask you to choose just two! Do you prefer wrecks, sealife, caverns, drift dives, underwater scenary, big stuff - some of each?
1. Barracuda Point, Sipadan Island, Malaysia
Wall of coral where sharks come cruising by and barracuda surround you. You are guaranteed to see big stuff here and lots of it. Occasional strong currents blast over an underwater prairie that's home to white tips, turtles, grouper, jacks, bumphead parrotfish and of course the barracuda that give it its name.
2. Blue Corner Wall, Palau, Micronesia
An upwelling means this splendid wall dive is favoured by pelagics. Expect to see sharks, barracuda, eagle rays, Napoleon wrasse, snappers, jacks...if you can tear your eyes away from the fish the wall hosts thick coral with morays, nudibranchs and mantis shrimps being just a few of the attractions.

3. The Yongala, Australia
The Yongala is a shipwreck off the coast of Queensland. Full of life you may see manta rays, sea snakes, octopuses, turtles, bull sharks, tiger sharks, clouds of fish and spectacular coral.
The Yongala sank during a cyclone in 1911 killing 122 people, a racehorse called Moonshine and a red Lincolnshire bull. She had no telegraph facilities and so could not be warned of the weather ahead. In 1981 the Yongala was given official protection under the Historic Shipwrecks Act. The ship is 90 km southeast of Townsville, 10 km away form Cape Bowling Green. 109 meters long, the bow points north and the ship lists to starboard.

4. Thistlegorm, Egyptian Red Sea
A large wreck which needs several dives to do it justice. A British vessel, the Thistlegorm (Blue Thistle) was attacked from the air and sunk in 1941 whilst carrying a cargo of war supplies: rifles, motor bikes, train carriages, trucks. Currents can be strong, and in different directions at the surface and at the wreck. Compare prices of Thistlegorm trips.
5. Shark and Yolanda Reef, Egyptian Red Sea
Three dives in one: anemone city, shark reef with its spectacular drop off and the wreck of the Yolanda. Currents make this good for drift dives and for pelagic fish. A popular dive starts at Anemone City before drifting to Shark Reef and its drop off. Finish up on the wreck of the Yolanda with its cargo of toilets.
6. Great Blue Hole, Belize
Very deep, wide, hole outlined by coral reef and inhabited by sharks. Is there another sight like it? 30 m visibility coming over the bathwater warm reef of vibrant colors, descending into a cool, deep blue hole where the water begins to waver and shimmer as you enter the transition from salt to fresh water at about 15 m. Watching the enormous tuna and other pelagics dive into the hole to clean themselves as you briefly remove your octopus to taste the fresh water. Then descending another 25 m to explore the stalagtites and stalagmites of ancient caverns. Compare prices of Belize diving trips.

7. Manta Ray Night Dive, Kailua Kona, Hawaii
Underwater lights placed on the ocean floor attract infinite amounts of plankton, which in turn attract the huge, yet beautiful manta rays of Kona Hawaii. The rays get so close to you, that you often have to move to avoid them accidentally hitting you. An amazingly wonderful and unforgettable time with one of the most beautiful animals in the world.

8. Navy Pier, Western Australia
Extending 300 m from shore, the T-shaped structure is 300 m wide, including two outlying "dolphins" (platforms for larger ships to tie up to). Although a very defined and somewhat compact site, you could spend 5 days diving there and not be bored, particularly at night. On any dive there are lots of nudibranchs and flatworms, eels, woebegone and white tipped sharks, octopuses, lion and scorpion fish, stargazers, and the usual smaller finned friends. Sometimes you'll come across absolutely huge rays dozing in the sand.

9. Richelieu Rock, Thailand
A horse shoe of rocky pinnacles, just breaks the surface at low tide. Famous for whale shark sightings, but also great for big schools of pelagic fish such as jacks, barracuda and batfish. Mantas are also seen, and it is a superb spot for Macro photography with such creatures as ghost pipefish, harlequin shrimp, frogfish and seahorses. Currents can be strong. Needs several dives to see the whole area. Compare prices of Richelieu Rock trips

10. The Liberty, Bali, Indonesia
This wreck is very popular with photographers as it is totally encrusted in anemone, gorgonians and corals. The black sand provides an excellent colour contrast for the incredible variety of marine life, which includes a huge school of big-eyed trevally and over 400 other species of fish. All the fish are very tame (partly as a result of some guides feeding them) from the goatfish and wrasse that nibble around your feet and fins at the end of the dive, to the unicorn and surgeonfish which make a beeline for your mask as you swim down towards the Wreck.
