Insurance for a Stage 1 Boat

Does anyone know of an insurance company that will insure an aluminium boat that is at stage 1 (all hot works complete and ready for fitout). I have just got a new boat and trailer and doing the fit out myself and was hoping to insure it for theft or accident while travelling . I have to take it back down south from Perth. Most of the standard boat insurance companies will only insure a finished boat. Any help would be much appreciate.
