- January 1841: The Brisbane River and its tributaries rose rapidly, causing significant flooding in the city. The flood waters reached a peak height of 12.7 metres (42 feet) above mean sea level, and the flooding caused considerable damage to buildings, infrastructure, and crops.
- February 1893: Another major flood occurred in Brisbane, with the flood waters reaching a peak height of 13.7 metres (45 feet) above mean sea level. The flood caused extensive damage to buildings and infrastructure, particularly in low-lying areas of the city.
- January 1974: The Brisbane River and its tributaries again experienced major flooding, with flood waters reaching a peak height of 12.5 metres (41 feet) above mean sea level. The flooding caused significant damage to buildings and infrastructure, including the city's main rail line.
- January 2011: The most recent major flood in Brisbane occurred in January 2011, when torrential rainfall caused the Brisbane River to break its banks and flood large parts of the city. The flood waters reached a peak height of 12.7 metres (42 feet) above mean sea level, causing extensive damage to buildings, infrastructure, and businesses.
These are just a few examples of the major floods that have occurred in Brisbane. The city has a history of flooding, and the risk of flooding is managed and mitigated through a range of flood mitigation measures, including flood levees, reservoirs, and dams.
