The whole response to the Speedway job wasn't by the book, 1) that part of the Sturt hwy is Renmark's area both MFS & SES, 2) page asked for lighting & according to people from my old unit they assumed that Renmark was on scene already & they were just to provide lighting - very surprised when they arrived and found out they were the rescue crew.
Footy my understanding is that it would not have mattered how quick, fire cover and rescue arrived on seen, the end result would have been the same (if you get my meaning).
As been said before, its not a perfect world!
