The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

Conodonts of Ludlovian-Gedinnian age from the Yass Basin of New South Wales are described. The fauna consists of 61 species referable to 24 genera of which one, Coryssognathus, is new. Four conodont assemblage zones are recognized and correlated with classic Ludlovian-Gedinnian zones of Europe; two faunas, one of probable latialatus Zone age and the other of probable woschmidti Zone age, have also been recovered. Reworked Ludlovian conodonts from Devonian conglomerates at the top of the Yass succession are also described.
