Jenolan to the 'Walls lookout could be done in a lowered Commodore and is a pretty nice little scenic run.
The Glow Worms trip actually annoyed me, many kms of potholed road.
Wombat holes is a bit of harmless fun near there (and you'd be going past it if headed to Glow worm), powerlines track is a bit more interesting though.
EDIT: last edit, boxhead did this up, track maps of the area:
