We all had to go to Sydney recently to get Lilah's US passport and citizenship. While there we stopped in at the Sydney Aquarium. It was very impressive. Eliana ran from tank to tank saying "more fish!", "blue fish", "big fish!". She had a ball.
The Aquarium had an awesome walk through tank with huge sharks and sting rays surrounding you.
We went for a swim underwater too.
We also stopped in at one of Australia's icon's - Circular Quay. You can see Sydney's 'famous' Harbour Bridge and Opera House in the background.
There are more photos of our time in Aus here.
