You want to stay well to the left of the gully. As Harvey said, it pretty obvious what you need to.
That track looks well to the right of where I would go.
There are two problems you have to address...the route to the base and the where you head up. I go left and steep and through the gaps. You can right and take a longer walk around to the class 2 walk up. It is just longer.
Oh, make sure you bring a pair of scree gaiters. You will need'em.
