|Great white nearly beaches itself in Australia|
The videographer states that the shark may have been sick or injured noting that the white pointer would repeatedly head off shore for about 50 yards and then turn around and come back to the beach.
The Marine Conservation Science Institute (http://www.marinecsi.org/) noted another possibility on their FB page stating that, "it looks like the shark is in a channel between the shoreline and a shallow sandbar, maybe trying to find its way out."
The video was posted on Youtube by Cadmonkey and is 1:42 in length.
[UPDATE: Sadly the shark was found dead when it washed up on shore two days later. It measured 4m in length. No mention at this time of the possible cause of death.]

Principal research scientist Dr Rory McAuley said the four-metre male shark had no visible signs of injury or disease, however it appeared the shark had a large Australian sea lion stuck inside its throat.
“This could explain why the shark was exhibiting such unusual behaviour in shallow waters off Coronation Beach. It is possible that the shark was trying to dislodge the blockage,” Dr McAuley said. “
Such a large object may have damaged the shark’s internal organs or impeded water flow into his gills, contributing to his death. Alternatively, the shark may have accidentally become stranded in his attempts to get rid of the obstruction.”
