Toowoomba Regional Council (TRC) covers approximately 13,000 km2. Across the region, flooding varies immensely from flash flooding in Toowoomba City to widespread, extended duration flooding along the Condamine River. In January 2011, the region experienced the worst flooding in its history.
Prior to 2008, the region was administered by eight separate local government authorities. Following amalgamation, the TRC was working towards updating and standardising the flood studies across the region. However, along with most of the state, the TRC area was hit by widespread flooding in the 2010/2011 wet season including the devastating flash flooding in Toowoomba City and the ‘Toowoomba Region Floodplain Management: Safer, Stronger, More Resilient Region’ program was significantly accelerated.
