G'day Mark, 

This fly wouldn't be suited to use on its own as it relies on the inner tent to support its shape. You would need something like an inner support pole to make it work, there is only a brow pole over the top. You might be better off with something like the OZtrail Hiker Fly. 

G'day Shirley,

We've just got one out to have a look at it for you. There aren't really any instructions provided by Oztrail other than the booklet they provide. There is a brow pole that reaches across the top from corner to corner of the top of the side zippers. Each corner can be separately pegged out. If you're having trouble maybe you can pop into the store on Richmond road and we can help you out.
