My brother, standing at the edge of Briggs Bluff in Victoria's Grampians National Park.
This impressive rock face drops around 1,200 feet, much of which is vertical, to the plain below.
On a windy day you have to scramble very carefully if you want to get to the edge, as an unexpected gust could easily sweep you out into the abyss.
Once you do make it though, sitting on one of the many overhanging slabs with your legs dangling hundreds of metres above the ground is quite exhilarating.
The Grampians are about 270 kilometres west of Melbourne. The isolation and primeval atmosphere of it's craggy peaks make it the perfect place to escape for a weekend.
(Unfortunately the quality isn't that great as it's an old film scan.)
