Jungle Circuit had been partially deleted by NPWS staff. NPWS has elsewhere deleted tracks despite them being still present on the ground. (At present survey is impossible as the descent from Govett's Leap is closed so I can't check in person.) I have asked for further information several times on the reverted changeset, but have not had a reply.
As NPWS seems to be discouraging access, I will add access=discouraged to these tracks (the entire loop, not just the parts NPWS had deleted).
Once the Govett's Leap descent is reopened, someone will need to resurvey to see if the track is still visible.
