yes its traffic these days, and its a good habit off finishing you call with mudgee traffic, or wereever you might be.
In NZ they dont or didnt when i did my training anyway
I think it is a good thing to repeat again after your transmission to wich traffic you were talking too.
sometimes you mis the initial place someone talks to. and if he/she finish with hooker creek traffic and you happen to decent in to VRD than you no you don't have to worry about him/her.
rather than go, "station calling were did you day you are?"
