Adelaide (equal fifth)
South Australia's unfairly-maligned capital has a lot to offer residents and visitors alike. Sometimes good things come in small packages, and this sunny, wide blue-skied city's best bits are easy to explore - from its expansive sandy beaches in the west, to its orchard-laden foothills in the east. There are advantages to being able to walk from one end of the city to the other in an easy stroll, allowing visitors to take in everything from the parklands to the botanic gardens and the cafe culture in between.
