The Galilee Basin Hydrogeological Model is a numerical groundwater flow model of the Galilee subregion in Queensland, an area of approximately 300,000 square kilometres. The model encompasses the entire geological Galilee Basin as well as parts of the overlying Eromanga Basin and surficial Cenozoic sediments. The model includes aquifers that form part of the Great Artesian Basin (specifically those aquifers in the Eromanga Basin), a hydrogeological system of national significance (see Evans et al 2018). The development of the Galilee Basin Hydrogeological Model represented an ambitious, first-pass attempt to better understand potential regional-scale cumulative groundwater impacts of seven proposed coal mines in the Galilee Basin (as known circa 2014, see Lewis et al. 2014 for details). This work was commissioned as part of the bioregional assessment for the Galilee subregion (https://www.bioregionalassessments.gov.au/assessments/galilee-subregion). Geoscience Australia has made the flow model and associated datasets available to support further academic or research investigations within the region. Importantly though, due to a number of limitations and assumptions (outlined in the final model report, Turvey et al., 2015), the model is not suitable for decision-making in relation to water resource planning or management. Further, the model was not developed to predict potential groundwater impacts of any individual mining operations, but provides a regional cumulative development perspective. The groundwater model and associated report were produced by HydroSimulations under short-term contract to Geoscience Australia in 2015. The report is referenced in several products released as part of the bioregional assessment (BA) for the Galilee subregion. However, due to the size, complexity and limitations of this model, this model was not used as the primary groundwater modelling input for the Galilee BA. Further detail about the key modelling limitations and why it was unsuitable for use in the Galilee BA are outlined in the BA Groundwater modelling report (Peeters et al., 2018).

This product is a rendered 3D model of one of the five ACT fossil emblem candidates, the brachiopod Retziella capricornae. The format of the file is ply. or Polygon File Format, and it is designed to store 3D data. The model requires no post-scanning manipulation as it is already complete. The purpose of this is to make this file format publicly available to local school communities so they can 3D print the fossil emblems themselves and engage students with Earth science related topics. <b>Acknowledgement:</b> Computed Tomography (CT) Scans and models generated at <a href="https://ctlab.anu.edu.au/">CTLab</a> - National Laboratory for X-Ray Micro Computed Tomography, Research School of Physics, The Australian National University (ANU), Canberra.

The depth to Proterozoic basement surface was constructed in order to delineate the thickness of Phanerozoic and more recent cover material. The "basement" refers to the Neoproterozoic and older rocks underlying the Canning Basin. The 3D surface was constructed using GoCad software and constrained by drill-hole data, Euler depth solutions and forward modelling using magnetic data, and interpreted depths from three seismic lines crossing the Waukalycarly Embayment. The depth to basement surface should be used as a guide. With the exception of the drill-hole data, there are uncertainties involved in estimating the depths based on the magnetic methods (Euler depth solutions and forward modelling), as well as the seismic data.

It is with great interest that we read the paper by Mueller (2015) who proposes that the majority of small pockmarks with diameters less than about 10 m on the northwest shelf of Australia may be of biotic origin, created by the fish Epinephelus, the Grouper. This hypothesis is based on a spatial association between pockmarks and Epinephelus at a number of sites on the northwest shelf and elsewhere around Australia, and on recent work undertaken on the habitats and observed behaviours of grouper fish in the Gulf of Mexico who excavate sediment from pre-existing solution cavities (Coleman et al., 2010; Wall et al., 2011). However, we contend that critical details have not been taken into account as part of Mueller's (2015) hypothesis, and additional consideration of existing geologic, geomorphic, sedimentologic and geochemical information is required. To make the science more robust, here we present a more comprehensive overview of the information available.
