You can approach GZ from a few directions, but personally I drove along Wattle Street through Colo Vale until the tarmac ended - fine for 2WD cars. Then I followed the fire trail to GZ, an easy walk of about 500m or so, crossed the shallow water, then there's a final minor bush scramble to GZ. There is a "private property" sign at one stage but that is for the land off to the right of the fire trail. There are some gates on the way but they are only for stopping vehicles and have gaps for pedestrians or mountain bikes. Indeed I met a friendly mountain bike rider on the way to GZ, and saw plenty of evidence of trail bikes. If you have a 4WD or don't mind dirt roads you may be able to drive closer via a different route which you can work out yourself.
Beyond GZ there is a tempting stump which does NOT contain the cache - beware the broken-down, abandoned and rusty section of barbed wire fence between GZ and this stump, which I walked into but got away with only a few scratches. Mind your footing around GZ as there are unfenced dropoffs.
You are looking for a 200ml Sistema and unfortunately I was out of logbooks so there's a post-it pad in there instead. Bring your own pen.
