The cash (Accuracy 4 m Elevation 9 m) is hidden in a 2.7 litre container with a few swaps as well as logbook and a pen, about 150 m south of the car park (S 40°57.405' E 174°58.234' Elevation 6 m). Simply follow the tram tracks to get there.
You may get to the car park from Sate Highway 1 by turning west at McKay's Crossing (S 40°58.219' E 174°58.885' Elevation 17 m) and continuing past the picnic areas to the end of the road (for about 2 km).
After finding the stash, you may like to visit the Lindale Centre (turn north-west off State Highway 1, about 8 km to the north-east of the McKay's turnoff, at S 40°54.307' E 175°01.319' Elevation 14 m). It is very touristy, but, they have a great selection of cheeses, icecreams, and honey products.
