Karawatha forest’s infertile soils and sandstone ridges were formed by many cycles of mountain building and erosion over millions of years. Some of the sandstone outcrops were laid down in the Triassic-Jurassic age when dinosaurs, not wallabies, grazed here. It is now home to Hank.
Suggest you carry a GPSr device that has a compass, basic map and measures distance. If you don’t have one of these, I suggest you go back to the carpark and have a picnic.
A positive Outlook will help with your quest. You will trip over Hank eventually.
You are standing at a three-way intersection of tracks wondering which way to go?
If you follow the Wallaby, you may run into a gate... now why is that there?
If you go the other way, you could go for a swim! Did you bring togs and a towel?
Anyway, if you started at the published coords (Casaurina track), that makes no sense, as you just came from that way and it was a mighty long walk. Hmm... unless you took a shortcut off to the right?
Through the trees you can see what appears to be a building with pipes coming out of it.
An abundance of helpful signs are scattered about.
You read the signs and decide to take the shortest route to nowhere.
“But why go nowhere when I could go somewhere,” you ask the CO?
“Because it’s probably a good place to hide a cache,” she responds, “as most bushwalkers like to go somewhere.”
You check out the signs and decide to take the shortest route which, coincidentally, goes nowhere.
“Ah! Now I get what she’s on about!” You run down the track for (roughly) 300-400 metres.
You come to a Y intersection and stumble up a short, steep incline to a clearing.
There is a lonely tree in the middle of the clearing.
Hank is so close you can almost hear him breathing!
Back to the tree, you walk about 25 metres south-east(ish).
You stop at the top of a gully where two large granite boulders rest with a log between them.
Best approach is from below as Hank’s Mailbox is well-hidden.
Do not attempt to extract the entire cache from the hidey hole! Oh no! Do not try that! Hank will get mighty grumpy (and so will the CO).
Hank’s Mailbox only opens at one end. You may need to squat down or lie on your belly to prise the lid open.
The FTF prize is located at the bitey end of the cache as I couldn’t fit it in the tin… It is securely-wrapped so take it with you. There is a small prize inside the Mailbox that you could leave for the next finder 
A useful tip: Hank’s Mailbox measures around 1 metre. If you can’t find it, don’t call the CO, call an Optometrist.
What do I do at the Mailbox?
IF HANK IS SLEEPING, DO NOT DISTURB HIM!!!
STAMP YOUR NOTEBOOK OR LETTERBOXING PASSPORT. SIGN (OR STAMP) THE LOGBOOK.
DO NOT REMOVE THE STAMP OR INKPAD FROM THE CACHE. REPLACE IN THE SEPARATE ZIPLOCK BAG.
ROOM FOR TRACKABLES ONLY (NO SWAG THANKS).
PUT EVERYTHING BACK THE WAY YOU FOUND IT!
AS ALWAYS IN BUSHLAND... BE RESPECTFUL AND TREAD LIGHTLY! YOU CAN STAY ON TRACK UNTIL ALMOST ON TOP OF HANK.
