The most populated city in all of Australia, Sydney has a very interesting past. Originally established in 1788 by British settlers, the city was started as a penal colony (a place where prisoners were sent in exile).
The city possesses one of the largest natural harbors in the world, and is known for its amazing views, bridges, and architecture.
Finally, Sydney has a pretty stable and growing economy, with emphasis being in manufacturing, finance, and of course, tourism!
