This signage is at the top of the mountain on the section of winding road called The Sidling. As you can tell from the signs it is on the highway from Launceston to Scottsdale in Tasmania.
I was out for a motorcycle ride this particular day & the weather was perfect for it. The Sidling is an awesome section of tight corners on a bike. There is a picnic area on the side of the road that I took the photo from. That was my lunch stop before U-.Turning & heading back home to Launceston.
