A security expert is warning Australians travelling to Bali as reports of violent thefts are increasing. Across coverage, the expert highlights that many incidents involve opportunistic criminals and that traveller awareness can reduce the risk of becoming targeted. The guidance focuses on practical personal-safety measures rather than specific allegations against particular groups or locations. Reported recommendations include maintaining situational awareness in public areas, staying alert to surroundings, and taking precautions to avoid confrontation when approached by potential offenders. The articles do not provide detailed statistics, specific incident accounts, or confirmed sources for the surge beyond describing it as an upward trend. Overall, the reporting presents the warning as a preventative message for travellers, urging caution and awareness while in Bali, and framing these steps as a general defence against opportunistic crime.
