If you are looking for work in that area you wil need several levels of traffic management training, as well as your whitecard. It is doubtful if you will secure employment without such. All training courses are redily available, and if you get a CITB card (free) then these courses are greatly reduced in price.
As per contents/advice on previous threads you really need to bite the bullit and go with the flow on getting tickets/training, a bit of a bind but a neccessity i'm afraid.
Are you restricting yourself to Adelaide City, as there is the State Gov as well as surrounding councils all worth a try. good luck
