This video was recorded during a Live Aboard on the boat Princess II (Rodney Fox White Shark Expedition) for 5 days 12-17 Jan 2014 at the Neptune Islands, 5 hours away from Port Lincoln in South Australia.
For 5 days, we were diving with the Great White sharks (inside the cage) both on the surface and also on the bottom of the ocean floor (26 to 30mts depth).

There is another video that shows a bit more of this trip at:

Netptune Islands and Guadalupe (Mexico) are the best places to dive with the White Sharks. In Neptune Islands (South Australia) the good part is that it is not deep and you can also see the sharks behavior at the ocean floor (as seen on the video links above as well).

The video shows the Shark going for the Bait (tuna) and it get's to be in between the two cages (individual) and group one, and it struggles a bit to get out and also the other part where comes fast for the tuna as strikes the cage as well.
The other part it shows the video when at the ocean floor and also the photos taken at the expedition with some of the white sharks ranging from 4 to 5.5mts (quite a lot of sharks - sometimes even 6 around the cage).
