This document discusses lessons learned from using social media in disaster management based on experiences with the Bundaberg Floods. It outlines five key lessons: 1) Pictures are worth 1000 words in effectively communicating information; 2) Information is a valuable currency that people constantly seek, like flood levels; 3) Information should be shared openly with the public without fear; 4) Misinformation will spread if information is withheld; and 5) Information must be consistent, legally defensible and withstand scrutiny. The document provides examples from the Bundaberg Floods to illustrate these lessons.
