If they've cut cores that's got to be a positive. They'll be looking at reservoir quality. Unlikely they would go to the time & expense to do that if the sand was below the GWL.
Dunsborough appraisal is good news. Light oil, and an accumulation of maybe 20 - 40mmbl (this appraisal might enable them to narrow that range a bit). That's around the size of Tui which is proving to be highly profitable for AWE et al.
