When we visited the Sea Life Sydney Aquarium we got to see not only small tropica fish but also large schools of the much larger fish due to the grand scale of the facility. Approximately half of the aquarium’s visitors come from overseas, and they’ve been flooding in since the complex opened in 1988. Many visitors come to see creatures that they have never seen before, such a platypuses and dugongs. In general, the exhibits that can be found at the Sydney Aquarium revolve around Australian themes, and the exhibit areas mostly pertain to different Australian regions and habitats. Some of the displays are housed in the main exhibit hall and others are housed in floating oceanariums. The Seal Sanctuary and Open Ocean exhibits comprise two massive oceanariums, amongst the largest in the world, and have underwater tunnels allowing visitors to examine marine life at close quarters. If you make it to Sydney, this should be on your “must do” list.
