The cache is not at the published coordinates but following the tradition of this style of cache it is a helpful starting & parking area once you've solved this puzzle:
The solution to the puzzle will provide you with necessary information about the location of the final hide (a micro inside small - BYO pen). The GZ coordinates were averaged over two separate days and the map seems to show a slight discrepancy, so resort to the GeoCheck hint (see below) if you have trouble...
Please don't publish any hints/clues in your logs or I will be forced to delete them... If you are truly stuck contact me for hints.
Use care at GZ - check for muggles and be aware they can come at you unseen! Please rehide the cache well.
Public transport available via tram (#70) and bus to Wattle Park, Burwood. There are public toilets available in the picnic area, as well as BBQ facilities. More information available here: Parks Victoria - Wattle Park
