Locals pronounce Brisbane as "BRIZ-bane"', as opposed to residents of the major Australian city Brisbane, who pronounce the name of their city as '"BRIZ-bun".
Brisbane is called "The City of Stars" because of a holiday tradition established over 65 years ago. At the start of the Christmas/Hanukkah season, many residents and business owners place large, illuminated stars, some as big as 10 feet (3.0 m) or more in diameter, on the "downhill" sides of homes and offices throughout Brisbane. As Brisbane is built on the eastern slope of San Bruno Mountain, visitors and residents entering at night are treated to a star-studded mountain vista. Many of the stars are kept up all year.
