Good on yer for referring it to PMAV.
And I must correct my previous assertion where I stated the map was published by Parks Victoria, I was rather slack with that as the maps are clearly published by the Victorian Environmental Assessment Council and NOT Parks Victoria. However the VEAC is still a government body and I assume these maps are an indication of what was proposed but, as S&D points out, never happened so they should probably be removed from their website as they will, inevitably, cause confusion for the public - as they have done here.
