This clip certainly doesn't do the event justice, but it gives a pretty good impression of just how many seals were hanging around this rocky headland near Jervis Bay. I thought it rather amazing that they could climb so high. I also found it very amusing watching them dive (well, fall in like drunken idiots) into the water. Very cool!
Side note: this place must be a great white feeding ground, but that didn't stop some foolhardy guys diving there! *shiver*
