The High Quality Geophysical Analysis (HiQGA) package is a fully-featured, Julia-language based open source framework for geophysical forward modelling, Bayesian inference, and deterministic imaging. A primary focus of the code is production inversion of airborne electromagnetic (AEM) data from a variety of acquisition systems. Adding custom AEM systems is simple using Julia’s multiple dispatch feature. For probabilistic spatial inference from geophysical data, only a misfit function needs to be supplied to the inference engine. For deterministic inversion, a linearisation of the forward operator (i.e., Jacobian) is also required. HiQGA is natively parallel, and inversions from a full day of production AEM acquisition can be inverted on thousands of CPUs within a few hours. This allows for quick assessment of the quality of the acquisition, and provides geological interpreters preliminary subsurface images of EM conductivity together with associated uncertainties. HiQGA inference is generic by design – allowing for the analysis of diverse geophysical data. Surface magnetic resonance (SMR) geophysics for subsurface water-content estimation is available as a HiQGA plugin through the SMRPInversion (SMR probabilistic inversion) wrapper. The results from AEM and/or SMR inversions are used to create images of the subsurface, which lead to the creation of geological models for a range of applications. These applications range from natural resource exploration to its management and conservation.

Geoscience Australia and the ANU Mathematical Science Institute have developed a new modelling tool called ANUGA for simulation of inundation and impact from hydrological disasters. The capability is based on a sophisticated mathematical model initially developed at the ANU and implemented to production standard at GA. It can model the process of wetting and drying as water enters a coastal community; it can model arbitrary geometries; it has unprecedented accuracy and it has a novel and easy-to-use interface

SUNAZ is a set of computer programs comprising SUNAZ and SUNIN to calculate azimuth-by-hour-angle observations of the Sun to determine true north azimuth to an azimuth mark based on the observing proforma described in K.A. Weinert (1980), Notes on Geomagnetic Observatory and Survey Practice, Earth Science 5, UNESCO, paragraph 246, page 36, using the algorithm described in G.G.Bennett (1980), "A Solar Ephemeris for use with Programmable Calculators", The Australian Surveyor, Vol.30, No.3, pp 147-151.
