Bandaneira is generally a safe place for tourists and there are no annoyances like in other Indonesian cities. Traffic is very little and calm.
Warning: There have been frequent reports of pickpocketing at the ferry terminal. The jostle upon arrival of the big Pelni boat is an ideal place to remove the wallet out of your pocket or to cut your money belt. It is advised to pay high attention and store your valuables safely!
Keep in mind that Indonesian ferries have generally low safety standards. In particular overloaded small boats e.g. to Pulau Ai might be hazardous during rough sea.
