It depends where you are.
In NSW there is legislation on the way to put building manager contracts on the same three-year limit as strata managers.
In Victoria they are thinking about doing something similar … some time … eventually … maybe.
And in Qld they’re talking about talking about it. But bear in mind that trade in caretaker contracts there runs to about $5bn a year, the official body for caretakers can get pretty feral when anyone says owners should have the right to choose who runs their buildings and the banks have a vested interest in keeping things exactly the way they are because they provide the loans so that caretakers can buy the contracts.
