In the La Niña year of 1974, an estimated 900 billion tons of rain fell throughout the state of Queensland in January alone. As Brisbane, Queensland’s capital city, prepared for its annual Australia Day public holiday on 26 January, a large monsoonal trough, associated with Cyclone Wanda, hovered above the 13,500 km² Brisbane River catchment. A slow-moving depression dumped huge amounts of rain, flooding local creeks and the Bremer River tributary upstream in Ipswich.
