The worst effect from storm surge appears to have been in association with the Friday night's high tide at Currumbin on the Gold Coast when cars were floating around the car park. This was not a big tide (0.74 m below the Highest Astronomical Tide--HAT) and therefore the wave effects appear to have added over a metre to the tide. Northeasterly gales in Moreton Bay early on Saturday raised the level of the Bay 0.7 metres.
