Australia is a popular destination for all types of travelers; therefore, some level of crime can be expected throughout the region. Foreign nationals may be vulnerable to low-level crime, including pickpocketing and theft of belongings when traveling through certain areas; displaying valuables can increase the risk of becoming a target. Female westerner travelers are occasionally vulnerable to serious sexual assault or harassment.
Be mindful of solo travel in remote or wilderness areas – Australia is subject to natural disasters (in addition to hazards of weather, flora, and fauna) and tourists can find themselves at risk if lost or stranded.
Terrorism does exist within Australia and terrorist groups have likely the intent to continue operations throughout the region. Melbourne has been targeted more frequently than other states in recent years, possibly due to its popularity with foreign travelers, however attacks could occur anywhere.
