The table illustrates how many tourists visited 6 different World Heritage sites every two years from 1996, 1998, and 2000
What is most striking when observing the table is that the number of visitors to the Great Barrier Reef, Blue Mountains, Tasmania Wilderness, and Shark Bay increased by varying degrees, whereas the popularity of Central Eastern Rainforest Reserve and Macquarie Island declined over the given period
Looking at the sites with increases, the Great Barrier Reef welcomed 3,200,000 visitors in 2000, twice as many as it did 4 years prior. Also drawing more tourists over time despite at lower rates, the Blue Mountains and Tasmania Wilderness attracted from 526,000 and 450,000 to 581,000 and 483,000 people over the 4-year period, respectively. Lastly, in spite of its lower rise rate compared to the mentioned four, the number of visits to Shark Bay still climbed from 84,000 to 102,000 from 1996 to 1998, followed by a plunge to 89,000 in the year 2000.
Regarding attractions with a decreased rate of visits, Central Eastern Rainforest Reserve attracted 20,000 fewer tourists every 2 years, yet remained one of the most popular sites among the six. Macquarie Island, however, experienced a modest quantity of visit only, with the rates ranging from 310 to 350 throughout the recorded period.
