There are various ways to approach GZ, but my recommendation is to park near where the railway line crosses Wilson Drive (see the Parking waypoint at S34 24.101 E150 29.301, near the Colo Vale information sign) and then walk along the abandoned train line to below the bridge. Take the usual precautions in long grass or walk along the rails themselves - hence the name of this cache. Once at GZ it should be an easy find, but please replace the camouflage as I suspect local muggles may enjoy a quiet drink here from time to time. Remember, you do not need to touch the bridge structure in any way to find this cache. You are looking for a 200ml Sistema, bring your own pen.
