The Sky Sports commentators, who are Down Under for the return Ashes series with England, were lowered into the water at Port Lincoln in a cage to get closer to the sharks.
Lloyd wrote in the Daily Mail: "One of them came within a couple of metres of my cage, so I thought it best not to stick my hand out and stroke him on the nose.
"Nasser preferred not to go in a second time. I think they might have taken one look at his hooter and sensed a kindred spirit."
