Normally, the Classic Adelaide has SAAS paramedics / ICPs following each stage, as well as a vehicle carrying RCR gear, and basic fire extinguishers.
There is an extensive plan for CFS response to fire - mainly with the thought of a car catching fire, and then setting the surrounding scrub alight....in most stages (and especially today) many CFS appliances are staged at the various access points along the route, ready for a quick response.
I think this year is a CAMS event....a few years ago, they went away from a CAMS sanctioned event, and arranged others to do the Marshalling work....and those officials we had to deal with were terrible!!!
The CAMS officials have a far better concept of how it all works, and what their responsibilities are (and more importantly, where their responsibilities end, and CFS start.....! )
