Petty Crime - There have been a few cases of handbags being snatched after tourists have chased money at Banks or Money Changers! Put your money away in your 'bum-bag' or hold onto your handbag tightly. When changing large amounts of money please check each note carefully as there are a number of (noticeably) fake notes in circulation. When trying on garments do not take your jewelry off and leave it lying around - give it to a friend or leave it in the hotel safe.

Swimming in the Sea - Currents / undertows can be strong, always swim between the red and yellow flags, do not swim too far out! Do not leave your belongings unattended on the beach.
