The township of Murwillumbah is located within the Tweed River catchment in northern NSW and is home to over 8,000 people. The township is surrounded by a number of waterways including the Tweed River, Mayal Creek and Rous River. Lavander Creek also drains through the town and discharges to the Tweed River via a culvert and pump system under Commercial Road.

The township is protected from flooding by 4 levee systems including Commercial Road Levee, East Murwillumbah Levee , Dorothy Street / Brothers Levee, and South Murwilumbah Levee. The levees provide varying degrees of flood protection though are generally considered to be less than the 1%AEP flood. A stormwater system and 2 pumping stations also work to help alleviate flooding associated with runoff behind the levee system.

Major floods in 1954 and 1974 resulted in inundation of the Murwillumbah CBD. Ex-tropical cyclone Debbie also caused significant inundation in early 2017. There has also been frequent minor flooding behind the levee system over the last decade due to high levels in the Tweed River inhibiting the performance of the stormwater system.
