Boeing Reserve is one of the largest reserves in Moonee Valley, stretching along Moonee Ponds Creek and linking to other parks and reserves by the Moonee Ponds Bike Path.
The cache is a dark, cylindrical container, medium jar sized and perfectly fits into its hidden place. (FYI seekers, there is maybe a little bit of variability in coordinates accuracy, because we used smartphones to obtain them)
However it shouldn't be difficult to find, all you have to look for is the small forest on the grass field. Easy walking distance from the car park or a nice ride with your bike along the path.
Have fun :)
