Any GPS coordinates for Newnes ?

I'm heading out to Newnes in a few weeks, visiting the main attractions like the Lost City and Glow Worm Tunnel. We will be heading in via the ZigZag and leaving via Blackfellows Hand track.

Can anyone give me some GPS coordinates for other points of interest in this area. Any off the track lookouts, sites etc.

I have also been told about amazing rock formations off the Sunnyside Track and also near Ben Bullen NP. Anyone have any info on these areas. Coordinates would be good.

I will have the Ben Bullen and Lithgow topo maps to work with, as well as the Boiling Billy treks book.

Any assistance is appreciated.
Thanks.
