More than 165 millimetres of rain has fallen on the Sunshine Coast in the last 24 hours, causing flash flooding and landslides. Up to 140 millimetres of rain has fallen on some parts of the coast in just three hours. Authorities were locked in an emergency meeting on Monday after six people were rescued from floodwaters. Two teenage girls who were stuck in a tree near Cooroy, west of Noosa, are safe and well after being rescued. Earlier, four people were pulled to safety from the top of their car. "For the first time ever, road crews in the northern region have run out of 'road closed' signs." There has been up to three metres of erosion on some beaches at the northern end of the Gold Coast and it is likely to get worse. "We've got some very high tides, king tides coming up tonight (Monday), tomorrow night and Wednesday night in the Noosa River that may well cause some local flooding and inundation out of the river."
