Brisbane started as a punishment. In 1824 the British opened a penal settlement for repeat offenders at Redcliffe, moved it to the river in 1825, and under Captain Patrick Logan it earned a reputation as one of the harshest in New South Wales. Queensland split off in 1859 and chose Brisbane as its capital. For a long time it was the city Sydney and Melbourne joked about. Then came World Expo 88, which turned a derelict riverbank into the South Bank parklands, and the city has been getting more confident ever since, with the 2032 Olympics on the way.
It is the easiest big Australian city to like. It is hot and humid, the river does most of the work, and you can swim in the middle of town at a beach with real sand. It's a city of outdoor tables, ferries and slow lunches, not of one famous skyline. Three days is the right length because the sights are close together: a gallery, a gondola ride, a bridge climb, a koala. You can see the lot without rushing, and still get a full day on an island.
Day one is South Bank, the river and the Story Bridge. Day two climbs Mount Coot-tha, visits the koalas and ends in Fortitude Valley. Day three is a boat trip to Tangalooma on Moreton Island. Start on a Thursday: the Valley is at its best on Friday night, and the island day lands on a Saturday, when the boats run to full schedule. Afternoon storms are normal in November and December, so outdoor parts come first and indoor ones fill the afternoon. More in Australia. The Gold Coast is about an hour south, and Sydney and Melbourne have their own guides.
