Lost in the confines of Western Australia, Perth is the capital of the sparsely populated side of the world: the city still exceeds one million inhabitants, gathered at the edge of the Swan River, near its mouth on the ocean Indian. It is today one of the most economically dynamic cities in the country. A former British colony, the city still has a few sites recalling the origins, as 13335 Kings Park, large green space in the city overlooking the buildings of Perth or Fremantle port and colonial architecture . The area also has many testimonials from the occupation of the Australian Aborigines, whose numbers in the region is very low today. Offshore, beyond the marked coast beautiful sandy beaches, the Rottnest Island (Rottnest Island), makes a stop '' paradise '' near the coast.
