Josef, as John has suggested, the recent fires in the grampians have burnt out most of the Serra range including the Green Gap Pinnacle.
Access to most of the central Grampians from Miranatwa gap in the south to Roses gap in the north is prohibited except for some of the main tourist roads and a very few walks.
I was involved in fighting the fires in January and have just retured from a weekend driving around the open areas checking out the damage. Believe me it is extensive, and it will be some considerable time before much of the park is opened to the public.
