Geology Early Pleistocene to Late Pliocene alluvial sediments (Warragul 1:250 000 Geology sheet). Following the notation of VandenBerg and O’Shea (1981), these sediments are believed to be mostly Qp5 with some later alluvium from the streams emerging from the hills to the west (see Geology and Geomorphology). |

Landform Level plain. This plain is only weakly dissected. Where it adjoins the Stratford map unit, it appears to be slightly lower in the landscape. This has caused the northern-most drainage lines emerging from the hills to flow north across the Toongabbie map unit into the Thomson River. | Part of the Toongabbie mapping unit from the air. |
