YIKES!!! Man leaps into the ocean and has a VERY close encounter with a Great White Shark!

MILWAUKEE (WITI) -- YIKES! A man jumps into the ocean in Sydney Harbour in Australia -- and has a VERY close encounter with a Great White Shark!

Video posted to YouTube shows the man strapping on a GoPro camera, high-fiving his friends -- and then leaping into the water near Manly Jump Rock in Sydney Harbour.

As the man surfaces, his friends yell "Shark!"

Seconds later...well...just watch!

(We do want to warn you -- there is some graphic language in this video clip!)

You'll want to watch to the end of the clip!
