I posted a section of my Perth Basin map on the EGO thread after a request. This might help you out.
Awe and Origin have the whole area stitched up (the Red circles filled with pink that are not on the key are held by Origin).
The Red boundary is the rough limits of the Kockatea Shale according to AWE and the Green boundary is the rough limits of the Carynginia Shale.
All the best...
