Four major floods have occurred in Brisbane.
The first was on 14 January 1841. This was the biggest flood of the Brisbane River since records began with the river being approximately 8.6 metres above the high tide mark. There was limited destruction to property as the town was still very young and undeveloped.
The next major flood began on 5 February 1893. These floods came within 7cm of the 1841 levels.
The worst floods in terms of death and loss of property occurred in January 1974 when tropical Cyclone Wanda developed into a rain depression that dumped hundreds of millimetres of rain on an already saturated southeast Queensland. This flood reached a height of 5.5 m. Since the construction of Wivenhoe Dam on the Brisbane River within a few years of this flood, Brisbane was believed to be flood-proof.
The most recent floods occurred inBbrisbane on 11 January 2011,when the Brisbane River again broke its banks. The flood was the result of a La Nina weather pattern, together with the state being saturated by the rainfall resulting from a cyclone system that hit in the north on Christmas Day 2010.
Wivenhoe Dam, which was designed to prevent any further floods, exceeded 160% capacity, requiring the release of a massive amount of water, comparable to the volume of Sydney harbour.

What was the name of the cyclone that caused the Brisbane floods to occur?
The Brisbane floods of 2011 were primarily caused by heavy rainfall associated with Cyclone Yasi, which formed in early February 2011. Although Cyclone Yasi itself did not directly hit Brisbane, the extensive rainfall and weather patterns influenced by the cyclone contributed significantly to the flooding in the region. These floods resulted in widespread damage and displacement across Southeast Queensland.

What natural disasters happen in Brisbane?
Floods and severe storms with hail are the most common natural disasters in Brisbane. These storms have become increasingly stronger in intensity, with lightning strikes and high, gusting winds causing major damage. Bushfires occasionally occur in the mountains around the city, but these never cause major damage. Cyclones very rarely reach as far south as Brisbane, the last one significant one being in 1974 when "Cyclone Wanda" dumped a huge amount of water in the Brisbane catchment, contributing to massive floods. Having said that, however, meteorologists are predicting more cyclones to occur near Brisbane in the 2010-2011 Summer season.
When did the 2009 Queensland floods occur?
There were two major episodes of flooding in Queensland in 2009. One took place in northern Queensland in February, and another series of floods affected large areas of the state including Brisbane in May.
Why did the floods hit Brisbane and not the Gold Coast?
It's a matter of where the Brisbane River flows. The Brisbane floods were largely a result of the massive amounts of water that had to be released from Wivenhoe Dam into the Brisbane River. The Brisbane River does not flow anywhere near the Gold Coast, but empties into the sea at Moreton Bay.
