An extreme weather system that has dumped in excess of 500mm on parts of southeast Queensland in the past 24 hours is expected to peak early tomorrow morning. Hundreds of calls for help have been made as wild weather continues to lash southeast Queensland but emergency services warn the worst is yet to come. There have been reports of landslides in northern NSW while warnings have been issued for extremely dangerous surf conditions. Emergency Services Minister Mark Ryan and his Queensland counterpart Greg Leach will provide an update on the conditions and response activities will provide an update on conditions at 3.30pm.
