This is one subject that will always be discussed heavily!
I personally think that what will happen eventually, is that a lot of the smaller MFS stations with small callout numbers will close and will revert to CFS.
The larger stations with more callouts will change to MFS and start at maybe retained or go straight to full time depending on call numbers etc.
Also, I think it would only be fair if this occurred, for crews to be selected from existing members of the particular brigades that are being changed over.
One reason I think it will happen like this is, (like already pointed out by others in this thread) is that the government (and unions) have said that there will only be one paid Fire Service in the state of S.A.
Like it or not, no one here makes the rules, so we will have to make the most of it when it happens!
There still is a possibility of one Fire Service, like what occurs in Tasmania, but I don't see them changing to this setup now seeing that both Fire Services are well established in S.A. and both have individual proud traditions that the government will not like to break!
(I believe that Tasmanian Fire Service has been all one service since day one - could be wrong)
Anyhow, could be interesting times..........
