In terms of stopping the SES, most of the time that I've seen them arrive at our jobs, we have had no idea that they were coming. It must be awful to go looking for a job thats already been done, but 'the nearest and most appropriate resource' should be used.
My suggestion would be to assume if it is storm, tree or flood incident, then SES is responding. Better to be informed that SES did not know about the job, rather than the volunteers travel for no job.
It is automatically assumed that if a fire or RCR exists in rural regions, then CFS is responding.
One of the new rules is that if the incident is car vs building, then SES will be responded for salvage. So if you respond to RCR & a building is involved, then give a quick stop call if no shoring/salvage required.
Ultimately SAFECOM SACAD will assist in resolving this. Hopefully an automatic address search for current incidents will be done within the computer system when a new call is received.
But you will always get the problem. Last year during a large storm event, Willunga CFS and Noarlunga SES (from LHQ at Lonsdale) were responded to a tree job at Willunga. We believe they were individual seperate telephone calls received, and neither organisation knew the other had responded resources.
The ultimate aim is for the emergency incident to be resolved quickly and safely as possible. So it does not matter who resolved the incident.
But all I ask is that you be aware that more resources from other organisations will being responded in case you need the extra equipment.
