Awesome!
A great value! A great aquarium. I've visited it each of the three times I have been in Sydney, and will visit the Aquarium again when I go in late December 2006, and in July 2007. Yes, its that good! Be sure and take your time and enjoy the exhibits. There is alot to see, and since you'll be on vacation, take your time. You'll love the underwater tunnels where you can watch large sharks and manta rays swim around and above you. A must see!
