Not sure but,
There is a trig station and the shed/structure if you look has a circular device in the roof with a wire hanging from the centre, that says to me that it is/was a fire spotting tower.
What initially threw me was the first thing I read when looking for verification was that Comboyne tower was closed to public access. (not sure what the situation is at the moment)
anyhow
This one is a bit historical,
