Per the website underwater.com.au....
Sea World keeps Dusky Whalers, three Tiger Shark and one Bull Shark in the Shark Bay enclosure…… and divers can enter the water from the Reef Lagoon…but you won’t be actually swimming with the big sharks. And only see them from behind glass….But will be forgotten…. You can still enjoy the show if you decide not to go into the water…as there are observation areas.
The trained staff do go into the tank with the sharks to do the glass cleaning… And I understand there is a waiting list for these brave souls wanting the same job.
