You are looking for a nano cache. You will need tweezers or a pin to access the log, and bring your own pen too.
Sally is a high flyer. You may be able to spot her from the ground but to claim the cache you will need to get up to her level.
Getting an accurate GPS signal was difficult under the tree cover. As you walk up the slope from the parking you will see a footpath marker and a steep slope to your left. You will just be able to make out a feint path going diagonally. This will lead you to where Sally is hiding.
This cache requires specialist climbing equipment, please only attempt this cache if you are confident of your ability to do so safely.
