What is the difference between the Great Barrier Reef in Phuket and the Great Barrier Reef in Australia? Why are the names the same?

When talking about the Great Barrier Reef, we generally refer to Australia, because the coral reefs there are very famous, are national treasures, and are listed as world-class natural heritage. They are famous far and wide. If you go to the Great Barrier Reef, you will definitely dive. The only way is to go into the sea. Only by diving can you truly feel the unique charm of the Great Barrier Reef. Then let’s talk about the Great Barrier Reef of Phuket. From the main island of Phuket, you will go to the sea and then you will go to an island. The scenery nearby is beautiful, the water is also very good, and there are also beautiful coral reefs and a large number of various fish. Phuket People thought it was completely comparable to the one in Australia, so they named that spot the Great Barrier Reef. If you go to the Great Barrier Reef over there, you will definitely know how to dive, whether it is deep diving or snorkeling, so there are two places. They are two completely different places far apart, but they also have coral reefs, tropical fish, beautiful seawater and people who come to enjoy diving. (I made it clear, hahaha. I understand personally. I just came back from Phuket.)
