Why do they call it the magnetic island?
Is wearing jewelry dangerous there?
Wikipedia has the answer to everything.
"The name of the island came about because of the apparent "magnetic" effect it had on the ship's compass of Captain Cook as he passed the island when sailing up the east coast of Australia in 1770.[2] People have since explored the general area of Magnetic Island with various instruments to discover what might have caused the effect that Cook reported, but nothing has been discovered."
