The foreign affairs department said in an official travel advisory that fans needed to be aware of safety issues at the World Cup, to be hosted by six Caribbean nations from March 10 until April 28.
"In some parts of the Caribbean, violent crime, including armed robbery, kidnapping and murder is common," the advisory said.
"Violent crime is often gang-related and perpetrators may be armed. There is also a high rate of petty crime, including pickpocketing and bag snatching. Walking after dark, including on beaches, can be dangerous due to the increased risk of robbery and assault.
"Crime, including sexual assault and robbery, has also occurred after travellers have accepted spiked food or drink."
Many Australians are expected to visit the Caribbean in large travel groups and the advisory said proper conduct was essential when catching flights.
"Australians travelling to the Cricket World Cup should be aware that airlines serving the Caribbean during the tournament will be refusing boarding to unruly passengers -- for example, those intoxicated, aggressive or otherwise behaving inappropriately," it said.
"Passengers refused boarding could face difficulties in re-booking accommodation at departure points and making alternative flight arrangements because of the expected high demand for these services."
