"... are you scared of shark attacks? " - In short no but I
never turn my back to the ocean and
never go deeper than my nipples. I still surf but not so much lately.
Yes that sounds paranoid but "we" have some of the largest Great White sharks in the world close to Adelaide.
"In 1974, footage of live sharks used in the 1975 American film, Jaws was filmed at Dangerous Reef by Ron Taylor."

Note the red marker. That's "Dangerous Reef" so if your ever in Adelaide don't forget to bring your swimming trunks...
