Crime Threats
The rate of crime in Papua New Guinea is among the highest in the world. Crime rates are highest in/around major cities (Port Moresby, Lae, Madang, Mount Hagen, Goroka), but crimes can occur anywhere.
Travelers should be particularly cautious of pickpocketing threats when in crowded public places, especially the local public markets. Bag-snatchers may try to open doors of automobiles that are stopped or moving slowly in traffic. Sophisticated criminal enterprises also exist, and their capabilities often exceed that of local law enforcement authorities.
U.S. citizens have been victims of violent crime, including gang rape, carjacking, home invasions, kidnappings, and armed robberies.Westerners may be perceived as wealthy, potentially making them targets of opportunity for criminals. Travel in groups and/or with an experienced guide. Be cautious of displays of wealth and keep valuables out of plain-sight; do not carry anything with you that you are not willing to part with if confronted. Change direction or depart the area if you become apprehensive of suspicious people, groups, or activities. Many of the businesses in Port Moresby have gated parking lots with guards on duty.
Carry your cell phone and inform others of your travel plans when possible. https://www.osac.gov/pages/ContentReportDetails.aspx?cid=22022
