The old boundary for the UXO area in the eastern section of the Budawangs, near Sassafras and Tianjara has recently been changed to now take in the whole of the Little Plateau. In 2015, the NPWS conducted a survey to check for ordnance in parts of the park which were originally determined to be outside the Tianjara Military Training Area. They found enough evidence to have the boundary for the UXO area extended to the south now taking in such wonders as Gadara Head and Nyaityung Falls and the whole of the Claydons Creek area.
I am told by both the ranger and the NPWS website that going off track is now prohibited with the potential of a heavy fine! Whether this would actually happen is hard to believe but the law is on their side and if you do head off, say to Talaterang Head, then you are going off trail and are subject to this prohibition.
Please see the attached to see the area now subject to the UXO restrictions.
