Damaging wind gusts of up to 90 kilometres per hour and dangerous surf conditions are expected to develop on Fraser Island tonight as Cyclone Ita moves south-east down the Queensland coast.
Parts of the Sunshine Coast have received heavy rainfall in the past 24 hours.
Forecaster Brett Harrison says Eumundi, Cooran and Cooroy recorded more than 100 millimetres and Mt Tinbeerwah 230mm.
"Even though we've had Tropical Cyclone Ita in the north and very heavy rainfall associated with that, the heaviest falls since 9:00am [AEST] yesterday have been on the Sunshine Coast," he said.
"So it was fairly localised with 230 being the highest that we saw at Mt Tinbeerwah."
