You are right, they need success.
But all the easy to find big oil bumps have been drilled world wide (Dunsborough nice cash flow but really only a small find ie less than 100 million recoverable). Only onshore Canning Basin, maybe CTP landholdings (high risk due to lack of source rocks) has the un-drilled bumps require to maybe find elephants onshore Australia (will maybe INP has in the Cooper).
