Which city is the fourth stop of the second stage of my wife's romantic journey?

My wife's romantic journey came to Perth, Australia in the fourth stop of the second season. This is a very beautiful city.

Perth is the fourth largest city in Australia and the capital of Western Australia.

Perth, located in the Mediterranean climate zone on the west coast of the Australian mainland, has become a very popular tourist destination because of its mild climate and unique scenery along the Swan River.

Perth has both modern high-rise buildings and rural customs. There are Catholic cathedrals, five universities and state capitol buildings in the city. On the wall of the mayor's office, there is a 4-inch-thick shell, which was left when the Royal Australian Navy battleship Perth sank in the Battle of sunda strait in March 1942.

The beautiful Perth is divided into two parts by a Swan River. St George Street on the north bank of Hebei Province is the center of the city's financial, commercial and government institutions, and is known as the office street. Haiyi Pedestrian Street adjacent to St. George Avenue in the north is the commercial center of Perth. Perth is also a place where black swans gather. It is called "Black Swan City", and there is a black swan on the sign of Western Australia Tourism Bureau.
