The long-running and toxic CFA industrial dispute could be drawing to a close with a plan to radically reshape firefighting boundaries.

There has been growing speculation that Labor will overhaul the state's fire services in the coming weeks by redrawing the boundaries of the city fringe fire-fighting zones and creating two new firefighting services: one wholly volunteer and one paid-only service.

Any changes to the boundaries are likely to be resisted by the Opposition and volunteer brigades and could cause another major political battle for the Premier.

Currently the CFA's mainly volunteer firefighters patrol the vast majority of Victoria, while the professional fire fighters of the Metropolitan Fire Brigade cover almost all of Melbourne.
