Been there several times, always something different. Free concerts at the Town hall every Tuesday at noon, no need to book, different program. If you want to visit clock tower, please keep in mind tours fill up and you will have to wait for at least an hour(which is not a problem with everything else going on). We had a wonderful tour of the building as well as clock tower-very informative. Great to see so much history and feel welcome by Brisbanites who are keen to share it.
