The ABC live blog gave an answer to this. The LNP will keep doing what it's doing. Federal members will sit in whichever of the two party rooms they used to sit in, and the state and council LNP members will stay unified. The latter is pretty obvious, since the federal Coalition has always been separate from state ones. NSW and Victorian coalitions have come close to splitting before, and that wouldn't have directly necessitated a split federally. They each have separate coalition agreements.
