We have just spent a month traveling the main cities in southern Australia and have to say that Sydney was the highlight! Even though it is home to more than 4 million people, we had no sense of the big city while there. People went out of their way to be friendly, helpful and courteous. The city itself has easily available restrooms, walking paths, shade areas, information booths and food! It was clean, calm and beautiful! The botanical garden was amazing! We would love to go back!
