The rapid advancements in communication and technology have had a profound impact on various aspects of society, including the behaviour of individuals and the operations of transnational organized crime groups. Despite the prevalence of drug-related offenses and the existence of transnational drug crime syndicates, there is a lack of in-depth studies on the offending patterns and methods employed by these syndicates in Thailand. This study aims to fill this research gap by examining the transnational drug crime syndicates related to Australia, exploring their operational patterns, methods, and coordination procedures between Thailand and Australia. Additionally, the study aims to analyse the challenges, obstacles, and limitations faced in countering these syndicates and provide recommendations for more effective strategies. This research employs a documentary review to collect relevant data, including case studies of drug offenses committed in Thailand and connected to Australia. Individual interviews and focus group discussions were conducted with executives and practitioners from local and foreign agencies involved in countering transnational drug crimes. T
