At the listed co-ords you will find a bench seat under a couple of very old mango trees within a dog off leash area.
Take a seat and ponder your next move.
Somewhere in front of you are representations of a number of dog breeds (there may also be real dogs but try to ignore them).
You will need to locate and correctly identify each dog then use the information they hold to work out the coordinates to the cache.
The cache is not too far away at S27 22.Dacshound, Boxer, Beagle E152 56.Cattle dog, German Shepherd, Poodle
