The parks remain open throughout the year but, it can be extremely hot from November to April and this is bushfire season: campfires are not permitted; parks, roads and recreation sites may have to be temporarily closed and events cancelled without notice. It can get very cold at night during winter and this is when the region experiences most of its rainfall. Go to the Bureau of Meteorology for more climate and weather information, including on sun protection. For information on what to do if you encounter a bushfire visit 'Bushfires and Prescribed Burns'.
Drinking water is not available in most of the parks and visitors are encouraged to take enough for their own use.
Some of the areas are Disease Risk Areas, which has to do with the preventing the spread of the plant disease Phytophthora Dieback (Phytophthora cinnamomi). More information on Dieback can be found here. Cars and bicycles are not allowed in Disease Risk Areas and walkers need to ensure that their shoes are cleaned before and after visiting these areas.
