Authorities are warning Sunshine Coast boaties not to attempt to cross dangerous sandbars and venture out to sea.
The Sunshine Coast council says there have been major sand shifts in the Mooloolaba Harbour and the Noosa and Caloundra bars, due to rough seas and powerful surf.
The Member for Maroochydore, Fiona Simpson, says marine pilots for container ships are only operating during daylight hours and conditions are still too dangerous for a survey ship to monitor sand movements.
