I've been finding caches in Sydney for a little over a year now, time to contribute to the population of geocaches here.
This cache is hidden on the edge of a small reserve; a paradise amongst the buildings, roads, railway and express way. There is an information sign near the cache to explain the park.
Tip: The cache is not amongst the rubbish on the light rail side of the wall.
Muggles may be an issue. It is a popular thoroughfare, even late at night. There are offices overlooking the general area.
