Please Note:
It is seagull breeding season and they can get somewhat agro when people approach their nests. If you are feeling uncomfortable, please give this cache a miss and seek out one of the other 3.4 million geocaches worldwide. 👍😀👍
Totally Findable Tourist Caches

Welcome to Sydney
This series of geocaches is designed primarily with visitors to Sydney in mind who may have limited time and transport options and want a quick and easy find while out enjoying some sightseeing around this beautiful city.
All cache containers will be one of three types; a flat magnetic key case (MKC), a round film canister (FC or MFC for magnetic) or a fake rock (FR).
The hint will indicate the type of container used and will be very specific to help you find the cache easily. If you want a challenge to find this cache and don't wish to know exactly where it's hidden, do not look at the hint.
At each location you’ll be given some information about the site you are visiting.
Enjoy!

At GZ, you are gazing across the Parramatta River.
The land adjacent to the Parramatta River was occupied for many thousands of years by Aboriginal peoples of the Wallumettagal nations and the Cammeraygal, Wangal, Toongagal (or Tugagal), Burramattagal, and Wategora clans of the Darug people. They used the river as an important source of food and a place for trade.
The river was formed 15 to 29 million years ago as its waters began to cut a valley into sandstone and shale.
Today, you can see the Rivercats that ply these waters taking passengers to and from the City of Parramatta, a distance of around 22km from Circular Quay. Perhaps you travelled on a Rivercat today to get to Cockatoo Island?
