mm echo in here - what Bros correctly said was "as it won't be a case of joining the mains you will need new ones."

As to who gets charged what, you need to confirm as it is not always as described by interd even in NSW. It depends who owns the pole and a few other matters too - I have been involved in a few cases where the moving of the pole was at no cost to the owner other than the new run of cable form the new location to the original connection point from the line end. So you need to talk to the utility about the specific circumstances rather than speculate.
