Australia’s third-largest city, Brisbane is the hub of Queensland culture, offering a peek at the past and a glimpse into the future. Visit the historic Windmill and Old Commissariat Store, built by convicts in 1828, or fast-forward to the present (and beyond) with a trip to the new Gallery of Modern Art. Mingle with locals atop Mount Coot-tha, cruise the Brisbane River to South Bank’s sandy beach on the City Cat and make sure to fill the cuteness quota at Lone Pine Koala Sanctuary, home to koalas and kangaroos.
