There's no need to jump in the garden, and if you reach the water then you've gone too far.
Be aware of the security camera in the pole to the north, security guards which patrol Barangaroo daily, and general muggles. Take your time and use stealth! As always, replace as found and ensure that cache has camo.
Whilst the cache is easy enough to find, the difficulty rating is set to reflect the problem with retrieving/replacing due to muggle activity.
Barangaroo was part of the territory of the Cadigal people, the traditional owners of the Sydney city region.
If you feel like exploring after you find the cache, continue following the path towards the city. Near the end of the cove, see if you can find the sign etched into the sandstone, highlighting what's left of the stone slipway from Munn's Wharf, built in the 1820's. Cuthbert's shipyard eventually covered and extended the old Munn's wharf, and the wharfs extended in size and operation from the 1850's onwards.
When this cache was placed, one of the obvious things was the Sydney Ports Harbour Control Tower (built in 1974), which stood above the park. The NSW Government finished demolishing it in 2017. Today, the entire foreshore is being redeveloped for business and residential purposes.
The redeveloped park itself was opened on Sat 22nd August, 2015.
The cachers from the Blue Mountains (west of Sydney) dared someone to hide an ammo box in this city location. Challenge accepted!
Enjoy the foreshore walk, the mid-level tracks, or the paths over the hill (Stargazers lawn).
