Magnetic Island was named such because of the magnetic deviation, not to be confused with magnetic variation. The source of deviation comes from mineral deposits so rich that they affect the magnetic reading on compasses. This was discovered in the 18th century by Captain Cook who spent time carefully recording the Australian coastline and creating navigational charts.
