Sydney, which sits on a spectacular natural harbor with famous landmarks like the Opera House, is Australia's oldest and most iconic city. The Sydney Opera House, whose striking design was controversial when first proposed by Jørn Utzon, is now recognized as a genuine world icon of modern architecture. Melbourne, where I spent three wonderful months exploring the cultural scene, surprised me deeply with its incredible arts and food culture. Australians, who are known internationally for their genuine friendliness and laid-back attitude, make excellent and generous travel companions wherever you go.
