A new exhibit of green tree frogs was unveiled for the school holidays this month at Sydney Aquarium, the first time the frogs have been on show at the attraction in four years.

Visitors can also try out the new glass-bottomed boat, Shark Explorer and see a new baby fur seal which was rescued after being found injured on Stockton beach near Newcastle last year.

Sydney Aquarium’s marketing manager, Thomas Davey, said: “The new Shark Explorer has already proved extremely popular, while the diversity of marine animals, both cute and scary, is a source of endless joy and fascination to our visitors from all over the world.”
