The Brisbane City Hall was built in 1930. The towering clock tower was the largest and most expensive building in Australia until the 1971 Sydney Opera House was built. The guides within the City Hall are free guided tours and need to be booked in advance on the official website. Departure time: 10:30, 11:30, 13:30, 14:30, 15:30 Duration: 45 minutes - 1 small clock building guideline The clock tower guide is a free guided tour, but reservations are not accepted. Travellers need to go to the Brisbane City Museum on the 3rd floor of the City Hall to pick up the ticket and wait for departure. It should be noted that due to a large number of people participating in the clock tower tour, it is recommended to get the ticket as soon as possible after arriving at the town hall. Departure time: 10:00-17:00, once per hour. Duration of the tour: In 45 minutes, I also went to the most expensive building. I liked to go shopping and did not participate in the tour.
