No muggles to worry about (most of the time). No ethical issues about grown adults prowling around playgrounds. A small container for swaps and trackables. And all in a nice bush setting on the edge of the suburban sprawl.
You are looking for a cylindrical, small stormwater pipe cache located above ground level. It's located a short distance off the track, so take care not to disturb snakes if approaching during the warmer months.
Please take the time to ensure the lid is properly screwed on and the cache hung so it's not as noticeable to the casual bushbasher - while muggles should theoretically not be a problem in this spot, previous containers have been disturbed or destroyed.
