My GPS Stash is in the Chichester State Forest between Dungog (in
the Hunter Valley) and Gloucester (West of Taree on the Mid North
Coast). I've called it Frying Pan because that's where we camp and
how I accessed the location. There are several other camping areas
in the vicinity with running water in the creek and bush(pit)
toilets. If you'd like to make this an overnight stop, it a good
place, has plenty of firewood (although you may have to collect it
yourself) and costs nothing, but facilities are limited.
The position was averaged for 5 minutes, and should be fairly
accurate, but the bucket is buried and covered with leaf litter so
will be difficult to see.
If you have difficulty finding it, there's more information
below, but I have made sure others in the area are unlikely to
stumble on it.
