Finally managed to trace some more walking trails around the 3 Sisters Katoomba.
As noted by the person who previously did some of these trails, it would be nice to redo them with a high res GPS. The Giants Stepwalk ended at least 50 m out at the bottom, and the new section around Leura falls is just a mess, so still trying to work out how to trace that one.
Did manage to accurately place Jenolan Caves though.

Mapping walking tracks is a real nightmare. I gave up attempting that some time ago as tree cover played havoc with my Garmin Vista. I do have a Vista HCX on order and it will be interesting to see how it goes.
In the upper Blue Mountains you have the added problem of high cliffs interfering with GPS signals.
