Which economic activity is only found on the eastern coast of Australia?

The only economic activity that is only found on the eastern coast of Australia is sugar cane farming. Sugar cane is a tropical crop that requires a warm, humid climate and plenty of water. The eastern coast of Australia, particularly the state of Queensland, has the ideal climate for growing sugar cane. The region receives plenty of rainfall and has a long growing season, which allows the sugar cane to mature and produce a high yield. Sugar cane farming is a major industry in Queensland and contributes significantly to the state's economy.
