Add a kiter to this and you could have yourself one big yo-yo.
Had a small bull shark (it looked like a bull shark anyway) jump out of the water last year at Burrum Heads but nothing like that video.
I doubt we would have the same sharks as you guys because I recently saw a documentary on Seabreeze that said sharks are only found in two places on earth - the northern and southern hemispheres
