Queensland Astrofest is held at the Lions Camp Duckadang, north of Linville. The above map will help you get there.
There are three low level cause ways between Linville and the camp as well numerous places where the roads can flood in the case of severe rain. The Somerset council has flood cameras covering various bridges in the area. These can be viewed at https://eservices.somerset.qld.gov.au/floodcams/
Select “Mount Stanley – Crossing No 1” for the camera closest to the camp.
Be aware of animals on the roads.
