Sydney Bay was discovered by European explorers in 1770. Populated at first by colonial convicts and their guards, the city today accounts for one fifth of the entire population of Australia. Renowned for its Opera House, it presents an ultramodern vista to the tourists’ gaze. Sydney Harbour Bridge - one of the longest bridges in the world - and the immense high-rise buildings that sore skywards both astound and fascinate. At the same time the great city is truly cosmopolitan, incorporating a celebrated Chinatown and even more prominently an Aboriginal area in which the colourful way of life of these first Australians is plainly to be seen.
