In my opinion, Australia is a continent. However, this is based on what I was taught in school. For a scientific comparison, check out this website. It poses some interesting facts and uses Greenland as an example for differentiating island vs continent.

I was also taught in school that Australia was a continent. I think that maybe it's a continent that is also an island. Whose to say that a place can't be both? One definition of an island is land that is completely surrounded by water. Another definition I found says the same thing but adds that an island is smaller than a continent. The whole thing is confusing so I say Australia is a continent. I think.

Comments: When I think about an island then Britain and Ireland is what I think about. An island like Jamaica comes to the mind even faster since most people tend to associate "island" with the Caribbean. Now you have this huge mass of land they call "Down Under" and you put any of us next to it and we look like an embryo. Australia is definitely a continent.
