A camo 200ml snaplock container (please do not rely on any pens/pencils being inside the container - always bring your own).
Couple of paces off path.
This is available anytime and can be accessed even at high tide. You can access it via the path which goes around the shop from the $2 contribution sign or from the beach via the DOC stairs (north of the cafe area).
At the lookout 150m away you can see the boulders and there was (at time of hide) an information board on what you can see.
