Setting up cameras at Will Rodgers State Beach, surfer Randy Wright says he has caught four great sharks on tape, and two of them in the past week alone.
Wright says that video was taken last Friday, before the Memorial Day weekend.
Lifeguards at the beach say they were instructed not to talk to the media about any shark activity on the coast.
But the area is historically known to attract Great whites.
In the past 5 years there have been only 4 reported shark attacks in the Malibu Sunset Beach area, described by Collier as "nips."
"When you look at them, most of the time they are scared of human beings," said Dominique Aris, an avid surfer in the area. Collier agrees, the sharks do not typically pose a threat to humans.
According to the Shark Research Committee, there were more than 20 confirmed sightings of a shark breaching at Sunset Beach throughout the summer last year.
Last October, Wright spotted what appeared to be a great white shark jump completely out of the water as he was kayaking 320 yards off the coast and took pictures of a great white shark, between 8-10 feet long, according to experts.
Collier confirmed the presence of what experts believed to be at least two great white sharks frequenting the waters off Sunset Beach.
Similar sightings were reported in the waters along Will Rogers State Beach, San Onofre State Beach, Huntington Beach and Terramar Beach in Carlsbad as well as near Santa Cruz island near Santa Barbara.
Sightings were also reported in the waters along the Central Coast and Northern California as far north as Oregon.
According to Collier, the number of shark sightings shows that these amazing creatures really "don't want to attack humans."
Collier says the number of sightings are up in the area, but more humans are also frequenting the area. He wants to raise awareness and says the report is not intended to frighten anyone.
The last fatal great white shark attack involved a swimmer who was killed on April 25, 2008 near Solana Beach.
Collier also says funding for shark research has dropped off due, in part, to the recession and he is asking for donations to help buy more tagging devices.
Anyone who would like to donate can go to shark research committee for more information.
Great white sharks are known to live in almost all coastal and offshore waters with the greatest concentrations off the southern coasts of Australia, South Africa, California and Mexico.
The great white is the world's largest known predatory fish which preys on smaller fish, dolphins, seals and sea lions.
