If you've wondered what goes down at an aquarium overnight, now is your chance to swim with the fishes (in a less sinister way).
The Sea Life Sydney Aquarium will now be open for 24-hour stints.
Starting on November 26, the event will showcase the Great Barrier Reef exhibition in a whole new way.
There will even be after-dark guided tours, running from 8pm, midnight, 2am and 4am.
