King tide flows over the South Arm HighwayFriday January 3, 2014 - 09:40 EDT
King tides have hit many Tasmanian coastal areas.
Tides reached their peak between 9am and 10am in the south yesterday, and at midday in the north.
The especially high tide event was expected to impact most Australian coastal areas.
King tides are a natural part of the tidal cycle, occurring twice a year.
But a cafe owner in Hobart, David Guiney, says he was surprised when Sandy Bay beach disappeared.
"Well it's the highest I've seen it and I've been here a long time, been here day to day for a long time, yeah it's the biggest I've ever seen it."
Communities across Australia are being encouraged to take photos of the event as part of the Witness King Tides project.
Organisers say the photographs offer a sneak preview of the threat posed by sea level rise.
