Rocklea is one of Brisbane 's most flood affected suburbs . Severe damage was experienced in both the 1974 Brisbane flood and 2010 – 2011 Queensland floods . Flooding in Rocklea is particularly harmful to the coastal ecosystem because of the oil and other toxic chemicals which are washed downstream . The effect of flooding on the Brisbane Markets was minor in 1974 but since then the site has grown five times and in 2011 35 buildings were inundated
