The line graph illustrates the number of overseas residents visiting Australia annually from 1975 to 2005, while the accompanying table provides information on the countries of origin of these visitors during the same period. Overall, the total number of overseas residents increased significantly over these three decades. Japan and South Korea emerged as the leading sources of tourists, whereas China consistently contributed the fewest visitors.
In 1975, approximately 8.8 million people visited Australia. This figure steadily increased, reaching 30.4 million by 2005. In terms of countries of origin, Japan had the highest number of visitors to Australia in both years, rising from 3.2 million in 1975 to 12 million in 2005. South Korea also experienced a notable increase, growing from 2.9 million to 9.1 million.
Meanwhile, the number of visitors from the USA, China, Britain, and Europe grew at a slower pace. For instance, the number of visitors from the USA increased from 0.4 million to 1.1 million, while visitors from China rose from a mere 0.3 million to 0.8 million. In summary, Australia became a significantly more popular destination for tourists, particularly for visitors from Japan and South Korea.
