Water is money. Since the earliest civilization of men, men go for the places with good water for living. Chinese started from the Yellow River and so did Indians.
All the popular cities of the world all next to good water like New York, Hong Kong, Shanghai and Singapore. Same theory is applied to Melbourne which has voted the most livable place in the world, is next to the Port Phillip Bay. The Qi that comes into the bay is well captured. The bay protects Melbourne against strong storms and wind. Melbourne is a city with good water and Qi.
