IntroductionIn recent years, globalization has grown exponentially, becoming a factor of influence in today's societies. The continued movement around the world of people from different countries and cultures has led to an increase in cross-cultural communication. Australia is quickly becoming a multicultural nation attracting tourists from a wide range of countries. As a result, it has become more important for Australians to be culturally sensitive and aware in order to successfully interact with these visitors from different cultures. These interactions are particularly important at international airports (Lie, 2003). Staff members are required to communicate with people from diverse cultural backgrounds, with varying degrees of English proficiency, and speaking different languages. According to the Australian Bureau of Statistics, the top international visitors in 2014 from non-English speaking countries were China, Japan and Singapore. The goal of this professional development resource is to train airport employees to communicate effectively with travelers from these three countries. This literature review will focus on the background research carried out in order to gain the knowledge behind the construction of this PDR. Concepts covered will be the relevance of intercultural communication, verbal and non-verbal communication, communication traits of China, Japan and Singapore and communication within airports.Intercultural CommunicationIntercultural competence is a key learning objective for this professional development resource. In order to become proficient, one must understand aspects of intercultural communication and the theories that have been proposed in the literature. degree of difficulty imaginable for other cultures to successfully learn and communicate in that language (Chiesa et al., 2012). English has not only become the official language in a large number of countries, but it has also become a nationally recognized language in many other countries (Chiesa et al., 2012). The use of English as a tool to aid international travel has led to the emergence of many language variations. Which leads to greater dissimilarity in communication within the English language. International airports are considered "modern cities" (Lie, 2003), which are the very product of globalization, leading to the increasingly important requirement for people of all cultural backgrounds to be sensitive and culturally aware in order to successfully communicate with each other..
