Just after 5pm on the day of the Lockyer Valley floods, Kym Charlton sent an urgent message from the Queensland Police Service Twitter and Facebook accounts:
"All residents living near the Lockyer Creek near Gatton and towns downstream are asked to evacuate their homes until further notice. A significant rise in the creek could inundate houses. All in low lying areas or near the creek are urged to move as soon as possible to higher ground."
Less than an hour later the message sent out via their Twitter stream (@QPSMedia) was even more urgent:
"Anyone living near Lockyer creek should IMMEDIATELY evacuate to higher ground. #thebigwet #qldfloods" (18.11pm).
