Perth is one of the most isolated big cities anywhere, and it behaves like it. The Whadjuk Noongar know this stretch of the Swan River as Boorloo, and the British founded the Swan River Colony here in 1829. The city that grew up has always looked west to the ocean rather than east to the rest of Australia. More than two million people live on a flat coastal plain between the river and the Indian Ocean, with a good chance of blue sky on any day you pick.
That is the real reason to give it five days. Perth itself is clean, easy and a little quiet, and the best things sit around it: a huge park on a hill in the middle of town, a convict-built port town, an island full of quokkas, white beaches that face straight into the sunset. November and December are the right months. Days run around 27 to 30 degrees Celsius with almost no rain, and every afternoon the sea breeze known as the Fremantle Doctor arrives to cool everything down.
The plan is organized by place rather than by sight. Day one covers Kings Park, the river and Northbridge, day two is Fremantle, day three is Rottnest Island, day four is the beaches at Scarborough and Cottesloe, and day five is a long day trip north to the Pinnacles. Start on a Thursday: Fremantle Markets only trade from Friday to Sunday, the beach day lands on a Sunday when public transport is free at the time of writing, and the long drive falls on a Monday when the roads are quietest.
