What are the reasons for the rapid development of major tourism resources and service industries in Australia?

Australia is a colorful and mysterious country. The blue sky, golden beaches, bright sunshine and green Yuan Ye and its unique rare birds and animals attract a large number of overseas tourists every year. Tourism has been playing a very important role in the Australian economy for decades. Australia's service industry includes logistics, telecommunications and postal services, financial services, tourism, retail business, construction and real estate. The service industry accounts for nearly 78% of the national GDP, and the employed labor force accounts for 70% of the national GDP, that is, 7 out of every 10 Australian employees are engaged in the service industry.
