Transcription: Hi, I'm Geoff and my job is to brief you on the desert and its wildlife so that you can make the best possible use of your time here with the least possible risk to yourselves. If you've heard it all before, you're free to leave at any time through the door on your right. These are the main briefing sessions we'll be giving. You can attend any of them in whatever order you like by just selecting the one you're interested in from this menu.
